Questions/results
heat energy, q, is calculated by multiplying
the specific heat, cp, of the material.
mass of the object in grams, m, by the change of temperature, mat, and
q=maticp)

1. calculate the heat lost from the bread at each interval. assume that the specific heat capacity of bread is 2.73 j/g °c.
2. calculate the heat gained by the water at each interval. assume that the specific heat capacity of water is 4.19 j/g °c.
3. based upon the results in questions 1 and 2, formulate a hypothesis regarding the transfer of heat between the
bread and the water.
4. identify at least one improvement that could be made to this experiment. justify your response in two or more
complete sentences.
5. what other household items could be used with your calorimeter? do you expect to get a different result? justify
your response in two or more complete sentences.
