A cube of ice has a mass of 1 kg and a density of 920 kg/m³. What is the volume of the ice (Density of materials)

The correct answer is 0.00109 m³.

Evidence lens: Use the data, graph feature, practical observation, or particle behaviour that proves the answer. This question asks: A cube of ice has a mass of 1 kg and a density of 920 kg/m³. What is the volume of the ice (Density of materials). The correct response is 0.00109 m³, 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 calculate mass when density and volume are known. 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 33 is distinct because it uses this exact question context and the evidence lens rather than a generic particle-model sentence.
