Which instrument would give the most accurate measurement of the sample’s mass for a specific heat capacity experiment?

The correct answer is A balance with a precision of 0.01 g.

Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. This question asks: Which instrument would give the most accurate measurement of the sample’s mass for a specific heat capacity experiment. The correct response is A balance with a precision of 0.01 g, because density links mass and volume, so the answer must preserve which quantity is being calculated. In Temperature changes in a system and specific heat capacity, the marking point should connect directly to apply AT 1 and AT 5 skills when measuring temperature, mass and energy transfer. 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 Internal energy and energy transfers, 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 361 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.
