A 1.5 kg block of ice is heated, causing its temperature to rise by 10°C. If the specific heat capacity of ice is 2,090 J/kg°C, what is the thermal energy change (Temperature changes in a system and specific heat capacity) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate thermal energy change when mass, specific heat capacity and temperature change are known) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate thermal energy change when mass, specific heat capacity and temperature change are known) ? P43-016 Temperature changes in a system and specific heat capacity checkpoint

The correct answer is 31,350 J ? P43-016 density measurement and calculation.

Unit lens: Check the units before giving the final statement so the physics quantity is not swapped. This question asks: A 1.5 kg block of ice is heated, causing its temperature to rise by 10°C. If the specific heat capacity of ice is 2,090 J/kg°C, what is the thermal energy change (Temperature changes in a system and specific heat capacity) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate thermal energy change when mass, specific heat capacity and temperature change are known) (Temperature changes in a system and specific heat capacity; particle reasoning focus: Calculate thermal energy change when mass, specific heat capacity and temperature change are known) ?. The correct response is 31,350 J ? P43-016 density measurement and calculation, 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 calculate thermal energy change when mass, specific heat capacity and temperature change 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 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 301 is distinct because it uses this exact question context and the unit lens rather than a generic particle-model sentence.
