What is the effect of energy transfer on the potential energy of particles during a change of state (Internal energy)

The correct answer is It increases the potential energy..

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: What is the effect of energy transfer on the potential energy of particles during a change of state (Internal energy). The correct response is It increases the potential energy., because changes of state are explained by particle energy and arrangement. In Internal energy, the marking point should connect directly to explain why energy transfer can change temperature without changing state. 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 247 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
