By Mayer's formula , we have
CP−CV =R
Where C and CV are the molar specific heats of gas at constant pressure and constant volume respectively.

V1/T1=V2/T2
T2=?
V1/27+273=2V1/T2
T2=2*300=600 K
T2=327 C

From ideal equation PV=MRT P=MRT/V
P=contact
MRT1/v1 =MRT2/v2
V1=V ,V2=2V, T1= 300K
300/V=T2/2v
T2=600K
T2 = 327°

T=27+273
V/T=2V/T
1/300=2/T
T=600K
T=327C
