What happens to the properties of a material when it undergoes a change of state and is then reversed (Changes of state)

The correct answer is The material recovers its original properties..

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: What happens to the properties of a material when it undergoes a change of state and is then reversed (Changes of state). The correct response is The material recovers its original properties., because changes of state are explained by particle energy and arrangement. In Changes of state, the marking point should connect directly to explain that the material recovers its original properties if a change of state is reversed. 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 189 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
