Questions/Results
Heat energy, Q, is calculated by multiplying the mass of the object in grams, m, by the change of temperature, mΔT, and the specific heat, Cp, of the material.
Q = mΔT(Cp)
Calculate the heat lost from the bread at each interval. Assume that the specific heat capacity of bread is 2.73 J/g °C.
Calculate the heat gained by the water at each interval. Assume that the specific heat capacity of water is 4.19 J/g °C.
Based upon the results in Questions 1 and 2, formulate a hypothesis regarding the transfer of heat between the bread and the water.
