Question: In which of the following scenarios is the entropy of the system likely to decrease?

Options:

Correct Answer: Water freezing

Solution:

The entropy of the system decreases when water freezes, as the molecules become more ordered in the solid state.

In which of the following scenarios is the entropy of the system likely to decrease?

In which of the following scenarios is the entropy of the system likely to decrease?

Step 1: Understand what entropy means. Entropy is a measure of disorder or randomness in a system.
Step 2: Recognize that when a system becomes more ordered, its entropy decreases.
Step 3: Consider the process of water freezing. When water freezes, it changes from a liquid to a solid.
Step 4: In the liquid state, water molecules are moving around freely, which means they are disordered.
Step 5: When water freezes, the molecules arrange themselves in a fixed structure (ice), which is more ordered.
Step 6: Since the molecules are more ordered in the solid state, the entropy of the system decreases.

Entropy – Entropy is a measure of the disorder or randomness in a system; it tends to increase in spontaneous processes.
Phase Changes – During phase changes, such as freezing, the arrangement of molecules can become more ordered, leading to a decrease in entropy.
