During which phase change do water molecules exhibit more freedom of motion?
Understand the Problem
The question is asking about the phase changes of water and during which specific phase change the molecules have increased freedom of motion. To solve this, we will reference the phases of water (solid, liquid, gas) and their characteristics in terms of molecular motion.
Answer
Transition to the vapor phase.
The final answer is the transition to the vapor phase.
Answer for screen readers
The final answer is the transition to the vapor phase.
More Information
When water transitions from liquid to gas (vaporization), its molecules gain more freedom of motion, moving independently of each other, which isn't the case in solid or liquid phases where intermolecular forces are stronger.
Tips
A common mistake is confusing liquid state with gas phase. Although molecules in a liquid have more freedom than in a solid, the greatest freedom occurs in the gaseous state.
