Question

How many joules of heat are needed to raise the temperature of 18.3 g of aluminum from

25°C to 70°C, if the specific heat of aluminum is 0.90 J/gºC?

Answer 1

The key to this problem lies with aluminium's specific heat, which as you know tells you how much heat is needed in order to increase the temperature of 1 g of a given substance by 1∘C.

In your case, aluminium is said to have a specific heat of 0.90Jg∘C.
