Question

$I$. The process of evaporation increases entropy.
$II$. The process evaporation is endothermic.

• A. Statement $I$ is true, Statement $II$ is true
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

The correct option is A Statement $I$ is true, Statement $II$ is true

The process of evaporation increases entropy, this is because evaporation converts liquid state of a substance to its gaseous state, which is characterized by randomness of the gas molecules.

Thus, there is an increase in entropy. Also, the process of evaporation is endothermic because heat energy is required to evaporate a substance.
