(d) internal energy. (e) work. 2. At a constant temperature, an ideal gas is compressed from 6.0 liters to 4.0 liters by a constant external pressure of 5.0 atm.
Problem Set 12 Solutions 1. What is the increase in entropy of one gram of ice at OoC is melted and heated to 500C? The change in entropy is given by dS = dQ T. In this case, the dQ must be calculated in two pieces. First there is the heat needed to melt the ice, and then there is the heat needed to raise the temperature of the system ...
