Question

According to third law of Thermodynamics, "At absolute zero, the entropy of a perfectly crystalline substance is taken as zero”.

• A. True
• B. False

Answer 1

The correct option is A

True

Yes, this is a true statement.

According to third law of Thermodynamics, "At absolute zero, the entropy of a perfectly crystalline substance is taken as zero”

Mathematically,

${lim}_{T\to 0}S\to 0$

Entropy of solids or liquids approaches zero at the absolute zero of temperature.
