Question 88

A student calculates the theoretical thermal energy needed to raise the temperature of a copper block from 25∘C25^\circ\text{C}25∘C to 55∘C55^\circ\text{C}55∘C.

She then performs an experiment to measure the actual electrical energy supplied to a heater to cause this temperature change.

State whether the measured energy will be greater than, less than, or equal to the calculated energy, and explain why.
