400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3.

(a) Draw a P-V diagram for this process.

(b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion?

(c) Calculate the work done by the gas.

(d) Calculate the initial temperature and final temperature of the gas.

(e) Calculate the change in internal energy of the gas.

(f) Calculate the heat added to the gas.
