Describe the method to determine the density of a liquid using a balance and a measuring cylinder.

To determine the density of a liquid, first measure the mass of an empty measuring cylinder using a balance. Then, fill the measuring cylinder with the liquid and measure the new mass. The density can be calculated by dividing the mass of the liquid by its volume, which is indicated on the measuring cylinder.

Application lens: Apply the rule to the specific sample or situation instead of reciting a broad fact. This question asks: Describe the method to determine the density of a liquid using a balance and a measuring cylinder. The correct response is To determine the density of a liquid, first measure the mass of an empty measuring cylinder using a balance. Then, fill the measuring cylinder with the liquid and measure the new mass. The density can be calculated by dividing the mass of the liquid by its volume, which is indicated on the measuring cylinder., 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 describe how to determine the density of a liquid using a balance and measuring cylinder. 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 91 is distinct because it uses this exact question context and the application lens rather than a generic particle-model sentence.
