When measuring the mass of a regular solid with a balance, which of the following actions will give the most accurate result (Density of materials)

The correct answer is Place the solid on the pan and wait until the balance stabilises before reading the scale.

Method lens: First identify the measured quantity, then match the equation or particle idea to the command word. This question asks: When measuring the mass of a regular solid with a balance, which of the following actions will give the most accurate result (Density of materials). The correct response is Place the solid on the pan and wait until the balance stabilises before reading the scale, 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 apply AT 1 and AT 3 skills when measuring mass and volume. 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 92 is distinct because it uses this exact question context and the method lens rather than a generic particle-model sentence.
