Question

How much heat energy is need to raise the temperature of 500.0 g of Aluminum from 15.0°C to 20.0°C? The specific heat of aluminum is 0.899 J/g°C. *

Answer 1

The amount of heat energy that is needed to raise the temperature of a system can be calculated by the product of the mass, heat capacity of a substance and the temperature difference. We calculate as follows:

Q = mC(T2-T1)
Q = 500 (0.899) (20 - 15)
Q = 2247.5 J
