Answer:
Copper>Steel>Aluminium
Explanation:
Hello,
Since the heat capacity accounts for the required heat to increase by 1°C, 1 kg of the metal, copper is the one that has the lower heat capacity, it means that it requires the least amount of energy to warm up (increase its temperature), this could be substantiated via the mathematical definition of heat capacity:

Solving for
:

It means that the lower the heat capacity, the higher the final temperature.
