Q: In which of the following scenarios is the entropy of the system likely to decrease?
Solution:
The entropy of the system decreases when water freezes, as the molecules become more ordered in the solid state.
Steps: 6
Show Steps
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.
