The temperature of 3.00 mol of an ideal diatomic gas is increased by 40.0 C° without the pressure of the gas changing.The molecules in the gas rotate but do not oscillate.

(a) How much energy is transferred to the gas as heat?

(b) What is the change in the internalenergy of the gas?

(c) How much work is done by the gas?

(d) By how much does the rotational kinetic energy of the gas increase?
