General physics

absolute scale

Physics; General physics

Temperature scale set so that zero is at the theoretical lowest temperature possible. This would occur when all random motion of molecules has ceased.

adiabatic cooling

Physics; General physics

The decrease in temperature of an expanding gas that involves no additional heat flowing out of the gas. It is the cooling from the energy lost by expansion.

adiabatic heating

Physics; General physics

The increase in temperature of compressed gas that involves no additional heat flowing into the gas. It is heating from the energy gained by compression.

air mass

Physics; General physics

A large, more or less uniform body of air with nearly the same temperature and moisture conditions throughout.

allotropic forms

Physics; General physics

Elements that can have several different structures with different physical properties-for example, graphite and diamond are two allotropic forms of carbon.
