Hello, I need help with this problem of thermodynamics 2?

A rigid and well-insulated deposit with a volume of 0.6 m3 is full of air. In said deposit there is a wheel of pallets that transfers energy to the air with a constant rate of 4 W during 1 h. The initial air density is 1.2 kg / m3. If there are no changes in the kinetic or potential energy, determine yourself... show more A rigid and well-insulated deposit with a volume of
0.6 m3 is full of air. In said deposit there is a wheel
of pallets that transfers energy to the air with a constant rate of 4 W during 1 h. The initial air density is 1.2
kg / m3. If there are no changes in the kinetic or potential energy,
determine yourself
(a) the specific volume in the final state, in m3 / kg.
(b) the energy transferred by work, in kj.
(c) the change in the specific internal energy of the air, in kj / kg
