Which of the following best distinguishes specific latent heat of fusion from specific latent heat of vaporisation (Changes of state and specific latent heat)

The correct answer is Fusion occurs at solid to liquid, vaporisation at liquid to gas..

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: Which of the following best distinguishes specific latent heat of fusion from specific latent heat of vaporisation (Changes of state and specific latent heat). The correct response is Fusion occurs at solid to liquid, vaporisation at liquid to gas., 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 define specific latent heat as the energy needed to change the state of one kilogram of a substance with no change in temperature. 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 371 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
