How much work done by motor to raise air temperature

A closed well insulated tank contains 10 kg of air at 300 K. An electric motor drives a propeller inside the tank until the temperature of the air has risen to 400 K. How much work had to be done by the motor to raise the air temperature by this amount?

U1= 1.41 kJ/kg

U2= 72.93 kJ/kg
