Question

100 POINTS!!!!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. Identify at least one improvement that could be made to this experiment. Justify your response in two or more complete sentences. 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. Submission Requirements Title of Lab: Data Tables: Questions/Results:

Answer 1

Yes i agree. I got it correct on the project.

Answer 2

Q = mΔT(Cp)
where Q = heat energy in J (joules),
m = mass in g, ΔT = change in temper. (°C),
Cp = heat capacity in J/(g°C)

Water has a higher heat capacity, meaning that once heat energy is absorbed, it holds that heat longer than bread. Also though, a higher heat capacity of water means that it takes more energy to heat it up.

I don't see any specific data listed for this lab??
