Problem 2.32

Two moles of a certain ideal gas at a temperature \(T_{0}=300 \mathrm{~K}\) were cooled isochorically so that the gas pressure reduced \(n=2.0\) times. Then, as a result of the isobaric process, the gas expanded till its temperature got back to the initial value. Find the total amount of heat absorbed by the gas in this process.
