Which of the following statements about entropy is TRUE?
AEntropy always decreases with time.
BEntropy of an isolated system always increases (or stays constant).
CEntropy is measured in joules.
DEntropy is another name for temperature.
Explanation
📌 The second law of thermodynamics: entropy of an isolated system tends to increase over time. This is the "arrow of time" of thermodynamics. Distractor A: exactly opposite; C: entropy is J/K (not J); D: confuses entropy with temperature.
