Problem 31CQ

Problem 31CQ

Explain how water’s entropy can decrease when it freezes without violating the second law of thermodynamics. Specifically, explain what happens to the entropy of its surroundings.

Step-by-Step Solution:

Solution 31CQ

Step 1 of 2

As per the second law of thermodynamics, every process is associated with an overall increase in entropy of the universe. The system and the surroundings

When the process of water freezing takes place, the movement of the molecules of water is restricted to a lesser value (since the movement of molecules is lesser in solids compared to that in liquids) or in other terms, the entropy of the system, the considered amount of water, falls.

From the second law of thermodynamics, this fall must be associated with a rise in entropy of the surroundings so that the total change in entropy is greater than zero.
