Short explanation

Explain freezing using decreased particle energy and changed particle arrangement. Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. In Changes of state, this means changes of state are explained by particle energy and arrangement. The answer should use the approved wording from Changes of state and the particle model, include freezing, and avoid drifting into another section of Particle model of matter. For revision, practise saying the exact objective aloud, then add the one calculation, particle movement, collision, graph, or practical detail that makes the statement true. A strong exam response for checkpoint 19 is specific to explain freezing using decreased particle energy and changed particle arrangement and does not reuse a generic explanation from a neighbouring objective.

Common mistakes

Misunderstanding Freezing: Emphasize that freezing occurs when particles lose energy, causing them to arrange themselves into a fixed structure, which is crucial for understanding the process.
