What is the effect of increasing temperature on the particle arrangement in a solid (Changes of state)

The correct answer is Particles vibrate more but remain in fixed positions..

Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. This question asks: What is the effect of increasing temperature on the particle arrangement in a solid (Changes of state). The correct response is Particles vibrate more but remain in fixed positions., because changes of state are explained by particle energy and arrangement. In Changes of state, the marking point should connect directly to explain melting using increased particle energy and changed 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 122 is distinct because it uses this exact question context and the practical lens rather than a generic particle-model sentence.
