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

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

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?
