Which of the following processes results in an increase in entropy?
A.Freezing of water at 0°C
B.Compression of an ideal gas at constant temperature
C.Mixing of two different gases
D.Formation of a crystal from a liquid
Explanation
Core Concept
Entropy is a measure of disorder or randomness. Mixing two different gases increases the disorder of the system, thus increasing entropy. Freezing, compression at constant temperature, and crystal formation all tend to decrease disorder and thus decrease entropy.
Correct Answer
CMixing of two different gases
