For Density of materials, which option correctly completes the metal block volume rearrangement calculation in the objective: Calculate volume when mass and density are known.?

The correct answer is The 300 kg mass divided by 7500 kg/m? gives 0.04 m?. (Density metal block volume rearrangement)..

Comparison lens: State both sides of the comparison so the contrast is explicit rather than implied. This question asks: For Density of materials, which option correctly completes the metal block volume rearrangement calculation in the objective: Calculate volume when mass and density are known. The correct response is The 300 kg mass divided by 7500 kg/m? gives 0.04 m?. (Density metal block volume rearrangement)., 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 volume when mass and density 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 41 is distinct because it uses this exact question context and the comparison lens rather than a generic particle-model sentence.
