Explain boiling using particles gaining enough energy to separate throughout a liquid.

Explain boiling using particles gaining enough energy to separate throughout a liquid. Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. 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 liquid, boiling, 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 20 is specific to explain boiling using particles gaining enough energy to separate throughout a liquid and does not reuse a generic explanation from a neighbouring objective.
