 Gas has a volume V1 =200cm3, at a temperature T1=300K and at a pressure P1=150000pa.

At STP temperature T2 =273.15K, the pressure P2=101325pa and the volume V2 is given by;

"P1V1\/T1=P2V2\/T2"

Hence "V2= P1V1T2\/P2T1"

               V2=150000*200*273.15/101325*300

                V2=269.59cm3
