Internal energy and work in gas processes

Air in a cylinder with a piston and initially at 20 °C expands at constant atmospheric pressure. (a) What is the work that the piston does on the gas if the air expands from 0.030 m3 to 0.043 m3? (b) How many moles of gas are in the container? (c) Suppose that the work leads to a corresponding change in thermal energy (there is no heating). What is the final temperature of the gas?
