alleryStart learning →The second law of thermodynamics states that all spontaneous changes cause an increase in:
ACharge on the atoms
BEntropy of the universe
CMass of the system
DVolume of the vessel
Answer & Solution
Correct answer: B. Entropy of the universe
1. The second law connects entropy directly to spontaneity.
2. The relation between entropy and spontaneity is a profound statement.
3. It is known as the second law of thermodynamics.
4. All spontaneous changes cause an increase in the entropy of the universe.
