Consider the following two-step process. Heat is allowed to flow out of an ideal gas at constant volume so that its pressure drops from P1 = 2.5atm to P2 = 1.3atm . Then the gas expands at constant pressure, from a volume of V1 = 6.3L to V2 = 9.1L , where the temperature reaches its original value.
Part A Calculate the total work done by the gas in the process.
Part B Calculate the change in internal energy of the gas in the process.
Part C Calculate the total heat flow into or out of the gas.
