When an ideal gas is compressed adiabatically (Q=0), work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its temperature drops. ... Nevertheless, because work is done on the mixture during the compression, its temperature does rise significantly.

Can temperature increase in an adiabatic process?

What happens to the temperature of an ideal gas in an adiabatic expansion? An adiabatic expansion has less work done and no heat flow, thereby a lower internal energy comparing to an isothermal expansion which has both heat flow and work done. Temperature decreases during adiabatic expansion.

Why does temperature change in adiabatic process?

Remember adiabatic process implies process in which no heat exchange takes place between the system and the surrounding i.e. neither heat is supplied nor heat is loosed. Temperature of gases changes only when internal energy of the gases changes. Temperature of the gas is related to du by du = nCvΔT.
