Quasi-liquid
Quasi-solid, Falsely-solid, or semisolid is the physical term for something whose state lies between a solid and a liquid. While similar to solids in some respects, such as having the ability to support their own weight and hold their shapes, a quasi-solid also shares some properties of liquids, such as conforming in shape to something applying pressure to it and the ability to flow under pressure. The words quasi-solid, semisolid, and semiliquid may be used interchangeably. Quasi-solids and semisolids are sometimes described as amorphous because at the microscopic scale they have a disordered structure unlike the more common crystalline solids. They should not be confused with amorphous solids as they are not solids and exhibit properties such as flow which bulk solids do not. Examples Petroleum jelly - a mixture of hydrocarbons extracted from crude oil and subsequently refined, has semisolid properties. It is used topically on human skin to promote healing of minor irritati ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

States Of Matter
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many intermediate states are known to exist, such as liquid crystal, and some states only exist under extreme conditions, such as Bose–Einstein condensates (in extreme cold), neutron-degenerate matter (in extreme density), and quark–gluon plasma (at extremely high energy). For a complete list of all exotic states of matter, see the list of states of matter. Historically, the distinction is made based on qualitative differences in properties. Matter in the solid state maintains a fixed volume (assuming no change in temperature or air pressure) and shape, with component particles ( atoms, molecules or ions) close together and fixed into place. Matter in the liquid state maintains a fixed volume (assuming no change in temperature or air pressure), but has a variable shape that adapts to fit its containe ...

Whipped Cream
Whipped cream is liquid heavy cream that is whipped by a whisk or mixer until it is light and fluffy and holds its shape, or by the expansion of dissolved gas, forming a firm colloid. It is often sweetened, typically with white sugar, and sometimes flavored with vanilla. Whipped cream is also called Chantilly cream (or crème Chantilly; ). Fat content The cream used as ''whipping cream'' has a high butterfat content—typically 30%–36%—as fat globules contribute to forming stable air bubbles. During whipping, partially coalesced fat molecules create a stabilized network which traps air bubbles. The resulting colloid is roughly double the volume of the original cream. If, however, the whipping is continued, the fat droplets will stick together destroying the colloid and forming butter. Lower-fat cream (or milk) does not whip well, while higher-fat cream produces a more stable foam. Methods of whipping Cream is usually whipped with a whisk, an electric h ...

Plasticity (physics)
In physics and materials science, plasticity, also known as plastic deformation, is the ability of a solid material to undergo permanent Deformation (engineering), deformation, a non-reversible change of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from Elasticity (physics), elastic behavior to plastic behavior is known as Yield (engineering), yielding. Plastic deformation is observed in most materials, particularly metals, soils, Rock (geology), rocks, concrete, and foams. However, the physical mechanisms that cause plastic deformation can vary widely. At a crystalline scale, plasticity in metals is usually a consequence of dislocations. Such defects are relatively rare in most crystalline materials, but are numerous in some and part of their crystal structure; in such cases, plastic crystallinity can res ...

Hand Sanitizer
Hand sanitizer (also known as hand antiseptic, hand disinfectant, hand rub, or handrub) is a liquid, gel or foam generally used to kill many viruses/bacteria/microorganisms on the hands. In most settings, hand washing with soap and water is generally preferred. Hand sanitizer is less effective at killing certain kinds of illnesses, such as norovirus and '' Clostridium difficile,'' and unlike hand washing, it cannot physically remove harmful chemicals. People may incorrectly wipe off hand sanitizer before it has dried, and some are less effective because their alcohol concentrations are too low. Alcohol-based hand sanitizer that is ''at least'' 60% ( v/v) alcohol in water (specifically, ethanol or isopropyl alcohol/isopropanol (rubbing alcohol)) is recommended by the United States Centers for Disease Control and Prevention (CDC), but only if soap and water are not available. The CDC recommends the following steps when using an alcohol-based hand sanitizer: # Apply product to ...

Toothpaste
Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. Toothpaste is used to promote oral hygiene: it is an abrasive that aids in removing dental plaque and food from the teeth, assists in suppressing halitosis, and delivers active ingredients (most commonly fluoride) to help prevent tooth decay (dental caries) and gum disease (gingivitis).American Dental Association Description of Toothpaste Owing to differences in composition and fluoride content, not all toothpastes are equally effective in maintaining oral health. The decline of tooth decay during the 20th century has been attributed to the introduction and regular use of fluoride-containing toothpastes worldwide. Large amounts of swallowed toothpaste can be toxic. Common colors for toothpaste include white (sometimes with colored stripes or green tint) and blue. Usefulness Toothpastes are generally useful to maintain dental health. Toothpastes containing fl ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fruit Preserves
Fruit preserves are preparations of fruits whose main preserving agent is sugar and sometimes acid, often stored in glass jars and used as a condiment or spread. There are many varieties of fruit preserves globally, distinguished by the method of preparation, type of fruit used, and place in a meal. Sweet fruit preserves such as jams, jellies, and marmalades are often eaten at breakfast with bread or as an ingredient of a pastry or dessert, whereas more savory and acidic preserves made from " vegetable fruits" such as tomato, squash or zucchini, are eaten alongside savory foods such as cheese, cold meats, and curries. Techniques There are several techniques of making jam, with or without added water. One factor depends on the natural pectin content of the ingredients. When making jam with low pectin fruits like strawberries either high pectin fruit like orange can be added, or additional pectin in the form of pectin powder, citric acid or citrus peels. Often the fruit will be ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gelatin Dessert
Gelatin desserts (also Jelly or Jello) are desserts made with a sweetened and flavoured processed collagen product ( gelatin). This kind of dessert was first recorded as jelly by Hannah Glasse in her 18th-century book '' The Art of Cookery'', appearing in a layer of trifle. Jelly is also featured in the best selling cookbooks of English food writers Eliza Acton and Isabella Beeton in the 19th century. They can be made by combining plain gelatin with other ingredients or by using a premixed blend of gelatin with additives. Fully prepared gelatin desserts are sold in a variety of forms, ranging from large decorative shapes to individual serving cups. Popular brands of premixed gelatin include: Aeroplane Jelly in Australia, Hartley's (formerly Rowntree's) in the United Kingdom, and Jell-O from Kraft Foods and Royal from Jel Sert in North America. In the US and Canada this dessert is known by the genericized trademark "jello". History Before gelatin became widely available as ...

Peanut Butter
Peanut butter is a food paste or spread made from ground, dry-roasted peanuts. It commonly contains additional ingredients that modify the taste or texture, such as salt, sweeteners, or emulsifiers. Peanut butter is consumed in many countries. The United States is a leading exporter of peanut butter and one of the largest consumers of peanut butter annually per capita. January 24 is National Peanut Butter Day in the United States. Peanut butter is a nutrient-rich food containing high levels of protein, several vitamins, and dietary minerals. It is typically served as a spread on bread, toast, or crackers, and used to make sandwiches (notably the peanut butter and jelly sandwich). It is also used in a number of breakfast dishes and desserts, such as granola, smoothies, crepes, cookies, brownies, or croissants. It is similar to other nut butters such as cashew butter and almond butter. History The earliest references to peanut butter can be traced to Aztec civilization ...

Mayonnaise
Mayonnaise (; ), colloquially referred to as "mayo" , is a thick, cold, and creamy sauce or dressing commonly used on sandwiches, hamburgers, composed salads, and French fries. It also forms the base for various other sauces, such as tartar sauce, fry sauce, remoulade, salsa golf, and rouille. Mayonnaise is an emulsion of oil, egg yolk, and an acid, either vinegar or lemon juice; there are many variants using additional flavorings. The color varies from near-white to pale yellow, and its texture from a light cream to a thick gel. Commercial eggless imitations are made for those who avoid chicken eggs because of egg allergies, to limit dietary cholesterol, or because they are vegans. History ''Mayonnaise'' is a French cuisine appellation that seems to have appeared for the first time in 1806. The hypotheses invoked over time as to the origin(s) of mayonnaise have been numerous and contradictory. Most hypotheses do however agree on the geographical origin of the sauce ...

Solid
Solid is one of the State of matter#Four fundamental states, four fundamental states of matter (the others being liquid, gas, and Plasma (physics), plasma). The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. The atoms in a solid are bound to each other, either in a regular geometric lattice (crystal, crystalline solids, which include metals and ordinary ice), or irregularly (an amorphous solid such as common window glass). Solids cannot be compressed with little pressure whereas gases can be compressed with little pressure because the molecules in a gas are loosely packed. The branch of physics that deals with solids is called solid-state physics, and is the main branch of condens ...

Salsa (sauce)
Salsa is a variety of sauces used as condiments for tacos and other Mexican and Mexican-American foods, and as dips for tortilla chips. They may be raw or cooked, and are generally served at room temperature. Though the word ''salsa'' means any kind of sauce in Spanish, in English, it refers specifically to these Mexican table sauces, especially to the chunky tomato-and- chili-based pico de gallo, as well as to salsa verde. chips and dip, Tortilla chips with salsa are a ubiquitous appetizer in Mexican-American restaurants, but not in Mexico itself. History The use of salsa as a table dip was first popularized by Mexican restaurants in the United States. In the 1980s, tomato-based Mexican-style salsas gained in popularity. In 1992, the dollar value of salsa sales in the United States exceeded those of tomato ketchup. Tomato-based salsas later found competition from salsas made with fruit, corn, or black turtle bean, black beans. Since the 2000s sweet salsas combining fruits ...

Guacamole
Guacamole (; (informally shortened to ''guac'' in the United States since the 1980s) is an avocado-based dip, spread, or salad first developed in Mexico. In addition to its use in modern Mexican cuisine, it has become part of international cuisine as a dip, condiment and salad ingredient. Etymology and pronunciation The name comes from Classical Nahuatl , which literally translates to 'avocado sauce', from ''āhuacatl'' 'avocado' + ''mōlli'' 'sauce'. In Mexican Spanish, it is pronounced . In American English, it tends to be pronounced , and this pronunciation is also common in British English, but is more common. History Avocado seeds were first found in the Tehuacan Valley of Mexico around 9,000–10,000 years ago (7000–8000 BCE) and had been domesticated by various Mesoamerican groups by 5000 BCE. They were likely cultivated in the Supe Valley in Peru as early as 3100 BCE. In the early 1900s, avocados frequently went by the name ''alligator pear''. In the 1697 bo ...
