Adiabatic
Definition
Occurring or taking place without exchange of heat with the external environment; a structural thermodynamic process or transformation in which the isolated physical system neither receives nor gives up thermal energy, the variation of internal energy being achieved exclusively through the mechanical work performed by or on the system.
