Which statement best describes the flow of liquids?

The correct answer is Liquids flow because their particles can slide past each other..

Practical lens: Link apparatus, readings, and uncertainty to the exact measurement named in the objective. This question asks: Which statement best describes the flow of liquids. The correct response is Liquids flow because their particles can slide past each other., because gas pressure comes from particle collisions with container walls. In Changes of state, the marking point should connect directly to use the particle model to explain why solids have fixed shapes and liquids and gases flow. 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 194 is distinct because it uses this exact question context and the practical lens rather than a generic particle-model sentence.
