To answer this question we have to compare the specific heats of each substance.

The specific heat of a substance is the amount of energy required to make 1 gram of a substance increase its temperature by 1 °C. The greater the specific heat of a substance the more energy it will be required to heat it up.

The specific heat of water is 4.18J/g°C and the specific heat of aluminum is 0.897J/g°C.

It means that the amount of energy required to heat water is greater than the one to heat aluminum.

It means that the answer is TRUE.
