Q1) There are four main thermodynamic processes that you learned from Unit 3: isobaric, isochoric, isothermal, and adiabatic. For each process below, classify it has one of these processes and then determine the signs of Q (the heat energy that flows into the gas), W (the work done by the gas), and AU (the change in internal energy of the gas). a) A container filled with an ideal gas has been submerged in a large water bath for a long time such that both reach thermal equilibrium. You then slowly compress the gas in the container. Assume the container is not well insulted so heat energy can easily flow back and forth between the water and gas and that the water bath is so large that its temperature does not change very much. b) A container filled with an ideal gas has a well-sealed piston that you put a pin in such that it doesn't move up or down. You then put the container over a burner to heat it up. c) A container filled with an ideal gas has a well-sealed piston that can move up or…
