calculate the net heat transfer to or from the air

Question

Air at 17⁰C and 1.1 bar occupies 0.05m³. the air is first heated at constant volume until the pressure is 4.4 bar and then cooled at constant pressure back to original temperature. Calculate

1. the net heat transfer to or from the air and
2. the net entropy change.

Given the for air C_p = 1.005 and C_v = 0.718 kJ/kg-K.
