How much heat is absorbed by a 57g iron skillet when its temperature rises from 6oC to 20oC?

Heat absorbed is given by multiplying the specific heat capacity with the mass of the substance and the change in temperature.

specific heat capacity of iron = 460.5 J/kg/k

therefore, heat = mcФ, where c is heat capacity, m is the mass of iron and Ф is change in temperature. Change in temperature is 14 (20-6), mass in kg (0.057 kg)

=460.5 * 0.057 x 14

= 367.48 joules

Hence, heat absorbed by iron will be 367.48 joules
