A 2 kg block of copper requires less thermal energy to raise its temperature by 1∘C1^\circ\text{C}1∘C than a 2 kg block of aluminium. Why is this?
Copper is a better conductor of thermal energy than aluminium.
Copper is a poorer conductor of thermal energy than aluminium.
Copper has a higher specific heat capacity than aluminium.
Copper has a lower specific heat capacity than aluminium.
