For each process (a-d), determine the values of the following three functions using the methods you learned in class: The work (w) The heat (q) • The internal energy change (AU) Assume ideal behavior. Use the equipartition values for the heat capacities. Give your answers in joules. For some of these processes, It may not be possible to calculate the value of all three functions. In that case, just write "Not possible to determine" for that particular function. a. A system at 200. K containing 0.200 mol of Ar(g) expands isothermally and reversibly from an initial volume of 1.00 L to a final volume of 1.50 L. b. The same system as described in a undergoes a transition between the same Initial and final states as described in a. In this case, however, the path is irreversible. c. A system containing 0.200 mol of Ar(g) is heated isochorically from 200, K to 300. K.

A 220-ft3 sample of gas at standard temperature and pressure is compressed into a cylinder, where it exerts pressure of 2000 psi. Calculate the work (in J) performed when this gas expands isothermally against an opposing pressure of 1.0 atm. (The amount of work that can be done is equivalent to the destructive force of about 1/4 lb of dynamite, giving you an idea of how potentially destructive compressed gas cylinders can be if improperly handled!)
Use the heat capacities of the products and reactants of the thermite reaction and the calculated H of the process to estimate the temperature of the reaction. Assume that all of the heat generated goes to increasing the temperature of the system.
