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.

Describe the meaning of entropy. Calculate the change of entropy for some simple processes. The second law of thermodynamics is best expressed in terms of a change in the thermodynamic variable known as entropy, which is represented by the symbol S. Entropy, like internal energy, is a state function. This means that when a system makes a ...
