Which thermodynamic law introduces the concept of entropy and states that the total entropy of an isolated system can never decrease over time?
A. Zeroth law of thermodynamics
B. First law of thermodynamics
C. Second law of thermodynamics✓ Correct Answer
D. Third law of thermodynamics
💡 Solution & Explanation
The second law of thermodynamics establishes the concept of entropy and dictates that the total entropy of an isolated system must increase or remain constant over time during any spontaneous process. The first law deals purely with the conservation of energy, while the zeroth law defines thermal equilibrium and temperature measurement. Entropy acts as a quantitative measure of thermal energy unavailability in physical systems.
