Which one has the highest boiling point

One mole of a monatomic ideal gas undergoes four thermodynamic processes as shown schematically in the $PV$-diagram below. Among these four processes, one is isobaric, one is isochoric, one is isothermal and one is adiabatic. Match the processes mentioned in List-$I$ with the corresponding statements in List-$II$.

List-$I$	List-$II$
$P$ In process $I$	$1$ Work done by the gas is zero
$Q$ In process $II$	$2$ Temperature of the gas remains unchanged
$R$ In process $III$	$3$ No heat is exchanged between the gas and its surroundings
$S$ In process $IV$	$4$ Work done by the gas is $6 P _0 V _0$
