Vedclass · Answer

(D) In an adiabatic process,the system is thermally insulated from the surroundings,meaning $dQ = 0$.According to the first law of thermodynamics,$dQ = dU + dW$.For adiabatic compression,work is done on the system,so $dW This implies $dU = -dW > 0$,which means the internal energy $U$ increases.Since internal energy of an ideal gas is a function of temperature $(U \propto T)$,the temperature of the system also increases.Therefore,the $Assertion$ is incorrect.Adiabatic processes are typically fast processes to ensure no heat exchange occurs with the surroundings.Therefore,the $Reason$ is also incorrect.Thus,both $Assertion$ and $Reason$ are incorrect.

$Assertion:$ In adiabatic compression,the internal energy and temperature of the system decrease.
$Reason:$ Adiabatic compression is a slow process.
