Question: Which of the following processes is endothermic and results in an increase in entropy?

Options:

Correct Answer: Dissolving salt in water

Solution:

Dissolving salt in water is an endothermic process that increases the disorder of the system, thus increasing entropy.

Which of the following processes is endothermic and results in an increase in entropy?

Which of the following processes is endothermic and results in an increase in entropy?

Correct Answer: Dissolving salt in water

Step 1: Understand what endothermic means. An endothermic process absorbs heat from its surroundings.
Step 2: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 3: Identify a process that is endothermic. For example, when salt (like sodium chloride) is added to water, it absorbs heat.
Step 4: Observe what happens when salt dissolves in water. The salt ions separate and spread out, increasing the disorder of the system.
Step 5: Conclude that dissolving salt in water is an endothermic process because it absorbs heat, and it increases entropy because the salt ions become more disordered.
