Which statement best describes the arrangement of particles in a liquid (Changes of state)

The correct answer is Particles are arranged in a regular pattern and can slide past each other..

Cause lens: Name the cause, then state the effect on particles, pressure, density, or energy. This question asks: Which statement best describes the arrangement of particles in a liquid (Changes of state). The correct response is Particles are arranged in a regular pattern and can slide past each other., 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 124 is distinct because it uses this exact question context and the cause lens rather than a generic particle-model sentence.
