Definitions for "Adiabatic Process"
Thermodynamic change of state in which no heat is added or subtracted from a system; compression always results in warming, expansion in cooling.
A process in which a system does not interact with its surroundings by virtue of a temperature difference between them. In an adiabatic process any change in internal energy (for a system of fixed mass) is solely a consequence of working. For an ideal gas and for most atmospheric systems, compression results in warming, expansion results in cooling. See dry-adiabatic process, moist-adiabatic process.
A process which occurs with no exchange of heat between a system and its environment.
a change of state with the air thermally insulated from its environment
