What happens to particle energy during the process of condensing?

The correct answer is Particle energy decreases.

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: What happens to particle energy during the process of condensing. The correct response is Particle energy decreases, because changes of state are explained by particle energy and arrangement. In Changes of state, the marking point should connect directly to explain condensing using decreased particle energy and closer particle arrangement. 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 Changes of state and the particle model, 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 151 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
