Recall and apply the equation energy for a change of state = mass x specific latent heat.

Recall and apply the equation energy for a change of state = mass x specific latent heat. Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. In Changes of state and specific latent heat, this means density links mass and volume, so the answer must preserve which quantity is being calculated. The answer should use the approved wording from Internal energy and energy transfers, include specific latent heat, 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 55 is specific to recall and apply the equation energy for a change of state = mass x specific latent heat and does not reuse a generic explanation from a neighbouring objective.
