In adiabatic process , heat exchange is zero but temperature change is not zero i.e. temperature of system changes in adiabatic process . Adiabatic expansion causes cooling up of system and adiabatic compression causes heating up of the system. Adiabatic Processes Learn what an adiabatic process is, how it differs from an isothermal process , and how to calculate the work and internal energy involved. Find out the relation between volume, pressure and temperature of an ideal gas in an adiabatic process , and see solved examples and diagrams.
