Vedclass · Answer

(D) For an adiabatic process,the relation between pressure and volume is given by $PV^{\gamma} = 	ext{constant}$.When the volume $V$ decreases during compression,the pressure $P$ must increase to keep the product constant.According to the first law of thermodynamics for an adiabatic process,$dQ = dU + dW = 0$,which implies $dU = -dW$.In compression,work is done on the gas,so $dW  0$.Since the internal energy $U$ is directly proportional to the temperature $T$ for an ideal gas,an increase in internal energy results in an increase in temperature.Therefore,adiabatic compression leads to an increase in both temperature and pressure.
