For Density of materials, which option correctly completes the liquid volume check calculation in the objective: Rearrange the density equation to solve for mass, volume or density.?

The correct answer is The calculation 500 ? 1.25 gives 400 cm? for the liquid volume. (Density liquid volume check)..

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: For Density of materials, which option correctly completes the liquid volume check calculation in the objective: Rearrange the density equation to solve for mass, volume or density. The correct response is The calculation 500 ? 1.25 gives 400 cm? for the liquid volume. (Density liquid volume check)., because density links mass and volume, so the answer must preserve which quantity is being calculated. In Density of materials, the marking point should connect directly to rearrange the density equation to solve for mass, volume or density. 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 45 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
