Halliday, Resnick & Walker — The Kinetic Theory of Gases: Problem 7

7 Suppose 2.80 mol of an ideal diatomic gas, with molecular rotation but not oscillation, experienced a temperature increase of 45.0 K under constant-pressure conditions. What are (a) the energy transferred as heat \(Q\), (b) the change \(\Delta E_{\text{int}}\) in internal energy of the gas, (c) the work \(W\) done by the gas, and (d) the change \(\Delta K\) in the total translational kinetic energy of the gas?
