Problem

The diagram below shows the variation in entropy with temperature for a substance that is a gas at the highest temperature depicted. Accordingly, which of the following statements is not true?

(a) The “zero point” is explained by the Second Law of Thermodynamics.

(b) The entropy of a substance increases with temperature.

(c) A solid has the least dispersed energy and the lowest entropy.

(d) The vertical line 1 corresponds to ΔSfusion.

(e) The increase in entropy for liquid  ⇌ gas is greater than for solid ⇌ liquid
