Question

What is the change in heat energy when 132g of copper at 32.2°C is raised to 45.0oC? The specific heat of copper is 0.385 J/g °C.

Answer 1

Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as: 

Energy = mCΔT
Energy = 132 (0.385) (45 - 32.2)
Energy = 650.50 J
