A flexible balloon contains 0.330 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7100 cm3 and a temperature of 24.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3.

A. What is the total heat Q supplied to the gas in the process? B. What is the total change in the internal energy ΔU of the gas? C. What is the total work W done by the gas? D. What is the final volume V?
