heat flow

1 kg of a perfect gas is compressed from 1.1 bar, 27°C according to a law pv 1.3 = constant, until the pressure is 6.6. bar. Calculate the heat flow to or from the cylinder walls,
(i) When the gas is ethane (molecular weight 30), which has c p = 1.75 kJ/kg K.
(ii) When the gas is argon (molecular weight 40), which has c p = 0.515 kJ/kg K.
