###### Question details

A 1 m3 tank contains 3 kg of compressed air. The tank is well insulated so that an adiabatic process can occur, and rigid so that the air can’t expand. A paddlewheel transfers 40 W of power to the gas for an hour.

a. What is the initial specific volume of the gas?

b. What is the final specific volume of the gas?

c. How much work transferred in this process?

d. What is the change in specific internal energy for the gas?
