Physics: In thermodynamics is designated as adiabatic process to one in which the thermodynamic system ( usually, a fluid that performs work ) do not Exchange heat with its surroundings. An adiabatic process that is reversible is called isentropic process. The opposite extreme, in which the maximum heat transfer, causing the temperature to remain constant, takes place is called isothermal process. Adiabatic refers to volumes that impede the transfer of heat to the environment
