Question

When a solid is converted into liquid, entropy :

• A. Becomes zero
• B. Remains the same
• C. Decreases
• D. Increases

Answer 1

The correct option is D Increases

when solid is converted liquid, the particles are relatively more free to move and randomness increases. Liquid state has more accessible microstates, so more distribution of energy and hence entropy increases.

Theory:

Entropy (S):

• Entropy is defined as a measure of randomness or disorder of a system.

• All-natural processes are spontaneous because of an increase in randomness
