Question: In which process does the entropy of the system decrease?

Options:

Correct Answer: Freezing of water

Solution:

The freezing of water results in a decrease in the entropy of the system as it transitions from liquid to solid.

In which process does the entropy of the system decrease?

In which process does the entropy of the system decrease?

Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Know that when a substance changes from a more disordered state to a more ordered state, its entropy decreases.
Step 3: Identify the process of freezing. Freezing is when a liquid turns into a solid.
Step 4: Recognize that when water freezes, its molecules become more organized and form a solid structure (ice).
Step 5: Conclude that during the freezing of water, the entropy of the system decreases because it goes from a liquid (more disorder) to a solid (less disorder).

Entropy – Entropy is a measure of the disorder or randomness in a system; processes that lead to a more ordered state typically result in a decrease in entropy.
Phase Transition – The transition of water from liquid to solid (freezing) is a phase change that involves a decrease in entropy due to the molecules becoming more ordered.
