Question

Unit of entropy is
(a) JK⁻¹ mol⁻¹ (b) J mol⁻¹
(c) J⁻¹ K⁻¹ mol⁻¹ (d) JK mol⁻¹

Answer 1

WHAT IS ENTROPY IN SIMPLE WORDS?

• The entropy of an object is a measure of the amount of energy which is unavailable to do work.
• It contributes to the randomness / chaos in the universe.

FACTORS AFFECTING ENTROPY

• If you increase temperature, you increase entropy.
• More energy put into a system excites the molecules and the amount of random activity.
• As a gas expands in a system, entropy increases.

S.I unit of entropy = JK⁻¹
