For each of the cases that follow, list as many properties of the equilibrium state as you can, specially the constrains placed on the equilibrium state of the system by its surroundings and/or its container. a) The system is placed in thermal contact with a thermostatic bath maintained at temperature T. B) The system is contained in a constant-volume container and thermally isolated from surroundings. c) The system is contained in a frictionless piston and cylinder isolated from its surroundings.
