Calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known.

Calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known. Cause lens: Name the cause, then state the effect on particles, pressure, density, or energy. 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, melting, boiling, 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 57 is specific to calculate energy transferred during melting, freezing, boiling or condensing when mass and specific latent heat are known and does not reuse a generic explanation from a neighbouring objective.
