1. Acetone has a heat capacity at constant volume of 61.50 J/mol K at 310 K when it is in the gas phase. Consider the system where 1.500 moles of acetone is placed in an adiabatic chamber at 330.04 K. It is allowed to expand such that during the expansion the temperature drops to 288.05 K. Calculate the work done and the change in internal energy for the system. Assume the heat capacity is constant over this temperature range. (ANS:...

Assuming no energy is transferred to or from the surroundings, calculate the final temperature of the water after all the ice melts.
Classically, the heat capacity of a chain of N 1-dimensional harmonic oscillators equals N k, i.e., it is temperature independent. Explain qualitatively why the heat capacity should decrease as T goes to 0 K.
