It is stored in specialized containers, such as vacuum flasks, to insulate it from room temperature. Liquid air can absorb heat rapidly and revert to its gaseous state.
1,1,1-Trifluoroethane1,1,1-Trifluoroethane, or R-143a or simply trifluoroethane, is a hydrofluorocarbon (HFC) compound that is a colorless gas. It should not be confused with the much more commonly used HFC gas R-134a, nor confused with the isomeric compound 1,1,2-trifluoroethane. 1,1,1-Trifluoroethane has a critical temperature of 73 °C. ApplicationsTrifluoroethane is used as a refrigerant either by itself or more commonly as a component of blended mixtures.
PropanePropane () is a three-carbon chain alkane with the molecular formula C3H8. It is a gas at standard temperature and pressure, but becomes liquid when compressed for transportation and storage.

HydrofluorocarbonHydrofluorocarbons (HFCs) are synthetic organic compounds that contain fluorine and hydrogen atoms, and are the most common type of organofluorine compounds. Most are gases at room temperature and pressure. They are frequently used in air conditioning and as refrigerants; R-134a (1,1,1,2-tetrafluoroethane) is one of the most commonly used HFCrefrigerants.
HydrocarbonIn organic chemistry, a hydrocarbon is an organic compound consisting entirely of hydrogen and carbon. Hydrocarbons are examples of group 14 hydrides. Hydrocarbons are generally colourless and hydrophobic; their odor is usually faint, and may be similar to that of gasoline or lighter fluid.
OxygenChemical element with atomic number 8 (O)–↑O↓Snitrogen ← oxygen → fluorine
NitrogenChemical element with atomic number 7 (N)–↑N↓Pcarbon ← nitrogen → oxygenIsobutaneIsobutane, also known as i-butane, 2-methylpropane or methylpropane, is a chemical compound with molecular formula HC(CH3)3. An isomer of butane, it is a colorless, odorless gas. Isobutane is the simplest alkane with a tertiary carbon atom, and is used as a precursor molecule in the petrochemical industry, such as in the synthesis of isooctane.
Atmosphere of EarthThe atmosphere of Earth consists of a multi-layered gas mixture (commonly referred to as air) surrounding the Earth's planetary surface, which is retained by gravity. Like the atmospheres of other planets, Earth's atmosphere also contains variable quantities of suspended aerosols and particulates that create weather features such as clouds and hazes.*As an Amazon Associate I earn from qualifying purchases.
