Question

1st Law of Thermodynamics -II In the following 2 step process, heat is allowed to flow out of an ideal gas at constant volume so that its pressure drops from 2.2 atm to 1.2 atm. Then the gas expands at constant pressure from a volume of 6.6 L to 9.1 L, where the temperature reaches its original value. To solve the problem, sketch the P-V diagram that shows the two steps with the point "a" being the the initial P-V value and "b" the final P-V value (at same temperature) {Note: Provide the sketch with your worsheet for a possible 2 extra credit points on the exam} Part A: What is the total work done by the gas in the process? (2 points) Part B: What is the change in the internal energy of the gas in the process? (1 points) Part C: What is the total heat flow into or out of the gas? (2 points)
