CP Heat Calculation Handout 1
Answer the following problems showing all work
Equation: ΔH = (m)(ΔT)(c) Other equations m = c = ΔT =
ΔT = TF - TI
where ΔH = energy flow/change of system
m = mass of system
c = specific heat of system _____________
TF = final temp
TI = initial temp

system __________
2. How much heat (in J) is released when 322 grams of water goes from a temperature of 84.0degC to 41.5degC?
3. What is the specific heat of a substance if the temperature of the substance is raised from 35.0degC to 98.3degC by adding 3.25KJ of heat energy. The mass of the substance is 365grams.
