1. For each of the cases that follow, draw a picture of thesystem being described and list as many properties of theequilibrium state as you can, especially the constraints placed onthe equilibrium state of the system by its surroundings.
a. The system is placed in thermal contact with a thermostaticbath maintained at temperature T.
b. The system is contained in a constant-volume container andthermally and mechanically isolated from its surroundings.
c. The system is contained in a frictionless piston and cylinderthat is exposed to an atmosphere at pressure P and thermallyisolated from its surroundings.
d. The system is contained in a frictionless piston and cylinderthat is exposed to an atmosphere at pressure P and is in thermalcontact with a thermostatic bath maintained at temperature T.
e. The system consists of two insulated tanks of gas connectedby tubing. A valve between the two tanks is fully opened for ashort time and then closed. (Note: Think through carefully aboutthe consequences of the tank being opened for a short time insteadof a long time – what would the difference be in the properties (Tand P) of the gas in the two tanks?).
