Match the following column
 

A	Adiabatic expansion	P	No work done
B	Isobaric expansion	Q	Constant internal energy
C	Isothermal expansion	R	Increase in internal energy
D	Isochoric process	S	Decrease in internal energy

In the adiabatic process is zero as dQ=0

So according to first law 

$dQ=dU+dW$

For expansion, dW is positive and dU will be negative.

For compression, dW is negative and dU will be positive.

In the Isothermal process, dU is zero as the temperature is constant.

In isobaric expansion, internal energy increases as temperature increases.

In Ischoric process, as volume is constant there is no work done.
