Question:

A researcher heats a sample of water in a closed vessel until it boils.

(a) Does the entropy of the water increase?

(b) Has the randomness of the molecules increased? (In other words, are there more physical positions that the molecules can occupy?)

(c) What else has increased that affects the entropy of the system?

The researcher now heats the water vapor from 400 K to 500 K, keeping the volume constant.

(d) Does the entropy of the system increase?

(e) Has the randomness of the molecules increased? (In other words, are there more physical positions that the molecules can occupy?)

(f) Why has an increase in temperature of the gas at constant volume caused an increase in entropy?
