If a liquid has a density of 1.2 g/cm³, what would be the mass of 100 cm³ of this liquid (Density of materials) (Density of materials; definition focus: Compare densities of materials using calculated or measured values) (Density of materials; definition focus: Compare densities of materials using calculated or measured values)

The correct answer is 120 g.

Cause lens: Name the cause, then state the effect on particles, pressure, density, or energy. This question asks: If a liquid has a density of 1.2 g/cm³, what would be the mass of 100 cm³ of this liquid (Density of materials) (Density of materials; definition focus: Compare densities of materials using calculated or measured values) (Density of materials; definition focus: Compare densities of materials using calculated or measured values). The correct response is 120 g, because the particle model explains the observable property using particles. In Density of materials, the marking point should connect directly to compare densities of materials using calculated or measured values. 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 112 is distinct because it uses this exact question context and the cause lens rather than a generic particle-model sentence.
