Explanation
Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: What is the specific heat capacity of a substance if 1,500 J of energy is required to raise the temperature of 3 kg of the substance by 10°C (Temperature changes in a system and specific heat capacity). The correct response is 50 J/kg°C, because specific heat capacity links energy, mass, material and temperature change. In Temperature changes in a system and specific heat capacity, the marking point should connect directly to rearrange the specific heat capacity equation for any required variable. 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 323 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
Common mistake
Rearranging Specific Heat Capacity Equation
Students often confuse the variables when rearranging the specific heat capacity equation, leading to incorrect calculations.
To fix this, practice identifying each variable in the equation E = m x c x delta theta and ensure you understand how to isolate each variable correctly.
