What happens to the temperature of a substance during a change of state (Changes of state and specific latent heat)

The correct answer is It remains constant..

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: What happens to the temperature of a substance during a change of state (Changes of state and specific latent heat). The correct response is It remains constant., 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 367 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
