Which equation represents the relationship for energy during a change of state (Changes of state and specific latent heat)

The correct answer is Energy = mass x specific latent heat.

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: Which equation represents the relationship for energy during a change of state (Changes of state and specific latent heat). The correct response is Energy = mass x specific latent heat, because specific latent heat concerns energy transferred during a state change with no temperature rise. In Changes of state and specific latent heat, the marking point should connect directly to apply MS 3b and MS 3c skills when rearranging and calculating with the specific latent heat equation. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Internal energy and energy transfers, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 443 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
