A 2 kg block of metal is heated, causing its temperature to rise by 15 °C. If the specific heat capacity of the metal is 500 J/kg°C, calculate the change in thermal energy of the block (Temperature changes in a system and specific heat capacity)

The change in thermal energy of the block is 15000 J.

Graph lens: Read the trend, flat section, gradient, or axis labels before explaining the physical meaning. This question asks: A 2 kg block of metal is heated, causing its temperature to rise by 15 °C. If the specific heat capacity of the metal is 500 J/kg°C, calculate the change in thermal energy of the block (Temperature changes in a system and specific heat capacity). The correct response is The change in thermal energy of the block is 15000 J., 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 327 is distinct because it uses this exact question context and the graph lens rather than a generic particle-model sentence.
