Short explanation

State that changes of state are physical changes. Method lens: First identify the measured quantity, then match the equation or particle idea to the command word. 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 physical change, 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 25 is specific to state that changes of state are physical changes and does not reuse a generic explanation from a neighbouring objective.
