One mole of a monatomic gas is taken through a cycle ABCDA as shown in the PV diagram. Column II give the characteristics involved in the cycle. Match them with each of the processes given in Column I.

Column I	Column II
(A) Process A→B	(P) Internal energy decreases.
(B) Process B→C	(Q) Internal energy increase.
(C) Process C→D	(R) Heat is lost.
(D) Process D→A	(S) Heat is gained.
	(T) Work is done on the gas.
