3. Specific Heat
Describes how much energy is required to raise an object’s temperature
A characteristic physical property
Represented by c
Amount of energy in J needed to raise the temperature of 1 kg of the substance by exactly 1 K.
Table 1 shows specific heats

4. Specific Heat Equation
Energy = specific heat x mass x temp. change
Energy =cm∆t

5. Practice Problem
How much energy must be transferred as heat to the 420 kg of water in a bathtub in order to raise the water’s temperature from 25°C to 37°C?
