It takes more energy to raise the temp of 100 g of water by 10 deg C
Explanation:
We're gonna use the specific heats of each compound to help us out here. The specific heat of water is about 4.18 J/gC, while that of aluminum is about 0.9 J/gC. The specific heat of a compound is defined as the amount of energy it takes to raise one gram of a substance by 1 deg C, so it takes 4.18 J to raise 1 gram of water by 1 deg C, while it takes 0.9 J to raise 1 gram of aluminum by 1 deg C.
Because of this (and the formula
So it takes more energy to raise 100 g of water by 10 deg C.
Hope this helps!
