Question
A large, insulated tank of contains 55 liters of water at a temperature of 20°C. You drop
in an uninsulated but water-tight plastic bag (itself of negligible mass) containing 30 g of
ice at a temperature of 0°C. This ice melts completely and comes into thermal equilibrium
with the water in the tank.
(a) What is the heat that flows into the contents of the bag?
(b) What is the change in entropy of the water in the tank? (Hint: Will thẹ water
temperature change by a measurable amount?)
(c) What is the change of entropy of the entire system of the water and the contents of
the bag?
(d) What is the change in entropy of the contents of the bag?
3. One mole of gas undergoes the cycle shown in the p-V diagram below.
