A calorimeter has a heat capacity of 1265 J/oC. A reaction causes the temperature of the calorimeter to change from 22.34oC to 25.12oC. How many joules of heat were released in this process?

Answer 1

q = heat

C_cal = heat capacity of the calorimeter = 1265 J/ºC

∆T = change in temperature = 25.12 - 22.34 degrees = 2.78ºC

q = C_cal x ∆T = 1265 J/ºC x 2.78ºC

q = 3517 J
