The specific heat of aluminum is 0.214 cal/g. oC. Determine the energy, in calories, necessary to raise the temperature of a 55.5 g piece of aluminum from 23.0 to 48.6oC.

For this problem, we use the formula for sensible heat which is written below:

Q = mCpΔT

where Q is the energy

Cp is the specific heat capacity

ΔT is the temperature difference

Q = (55.5 g) (0.214 cal/g ·°C) (48.6°C - 23°C)

Q = 304.05 cal
