value of the constant pressure

Air having a volume of 0.04 m3 , a mass of 0.0961 kg and a temperature of 290 K expands at constant pressure to a volume of 0.12 m3 . An electric coil passes through the system boundary, and the coil receives a current of 5 amps at 12 volts for 2 minutes so that electrical work is done on the air during the expansion, while there is also a heat transfer. Calculate (a) the value of the constant pressure and (b) the value of the heat transfer
