Answer» 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.HOPE IT HELPED YOU MARK ME AS BRAINLIST
