Question

**Understanding Entropy in the Vaporization of Water**

Two different samples of water, one at 25°C and one at 100°C, are vaporized. Assuming that the ΔH_vap does not change, which process involves a greater change in entropy, ΔS?

a. Vaporization from 25°C
b. Vaporization from 100°C

**Explanation:**

This problem requires an understanding of how entropy (ΔS) changes during the vaporization process at different temperatures. Although both samples are undergoing the phase transition from liquid to vapor, the initial temperatures are different, which affects the degree of disorder (entropy) change in the system.
