Heat flows into an ideal gas at a constant volume. The pressure increases from 1.5 atm to 5.5 atm. Next the gas is compressed at constant pressure from 5.0 L to 2.5 L and goes back to its original temperature.
What is the total work done on the gas in the process?
What is the total change in internal energy?
What is the total heat flow of the process?
