Question

Quizplus · Accepted Answer

The condensation of water vapor on windows results in the liquid molecules moving from a randomly arranged state in water vapor to a more ordered state in liquid droplets, resulting in a decrease in entropy. Thus, the process B is the only result in a decrease in entropy of the universe. Option A and Option C both involve heat transfer between hot and cold bodies, which lead to an increase in the entropy of the universe per the second law of thermodynamics.
