$P V = n R T$ $PV=nRT$

$=>T=(PV)/(nR)....(1)$

Where

$n->"Number of moles of gas"=4 "moles"$

$V->"Volume of gas"=5dm^3$

$P->"Pressure of gas"=3.32" bar"$

$T->"Temperature of gas"=?$

$R->"Ideal gas constant"=0.083dm^3"bar"K^-1mol^-1$

Inserting values in (1)

$=>T=(PV)/(nR)=(3.32"bar"xx5dm^3)/(4molxx0.083dm^3"bar"K^-1mol^-1)$

$=>T=50K=50-273=-223^@C$
