Cooling is removal of
heat, usually resulting in a lower
temperature and/or
phase change. Temperature lowering achieved by any other means may also be called cooling.

The
transfer of
thermal energy may occur via
thermal radiation,
heat conduction
Conduction is the process by which heat is transferred from the hotter end to the colder end of an object. The ability of the object to conduct heat is known as its ''thermal conductivity'', and is denoted .
Heat spontaneously flows along a te ...
or
convection. Examples can be as simple as reducing temperature of a coffee.
