initial                                                         final

P1 = 710mm   = 710/760   = 0.934atm                                          P2 = 1.2atm

V1 = 740ml                                                                                      V2 = 460ml

T1 = 35+273   = 308K                                                                    T2 =

                       P1V1/T1            =         P2V2/T2

                              T2              = P2V2T1/P1V1

                                               = 1.2*460*308/0.934*740   = 245.98K
