"A cylinder contains 0.25 mol of carbon dioxide (CO2) gas at a temperature of 27C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 1 atm on the gas. The gas is heated until its temperature increases to 127C. Note that some work W is done by the gas in this process. Assume that the CO2 may be treated as an ideal polyatomic gas with three translational degrees of freedom and three rotational degrees of freedom. How much heat Q was supplied to the gas?"
