A student works out the energy required to increase the temperature of an aluminium block from $50^\circ\text{C}$ to $60^\circ\text{C}$. He then carries out an experiment to measure the energy needed for this change. Which statement about the measured energy is correct?
- AThe measured energy will be greater than the calculated energy because some energy is transferred to the surroundings.
- BThe measured energy will be greater than the calculated energy because the block absorbs energy from the surroundings.
- CThe measured energy will be less than the calculated energy because the mass of the block decreases as it gets warmer.
- DThe measured energy will be less than the calculated energy because the thermal capacity of the block is low.
