What is the total heat capacity of the calorimeter?

What is the Heat capacity of a common laboratory calorimeter ?

  • It happened that our group didn't really have the time to find the heat capacity of the calorimeter we used. Do you have any idea as to what a common laboratory calorimeter's heat capacity might be? The only thing I know about it is that it was a copper calorimeter with a weight of 485 gms. Please do not answer if you only want to give the value mass of calorimeter * sp. heat capacity of Cu, since we have already tried that but the results are that are coming are quite farther from what they should be.

  • Answer:

    A calorimeter constant (denoted Ccal) is a constant that quantifies the heat capacity of a calorimeter. It may be calculated by applying a known amount of heat to the calorimeter and measuring the calorimeter's corresponding change in temperature. In SI units, the calorimeter constant is then calculated by dividing the change in enthalpy (ΔH) in joules by the change in temperature (ΔT) in kelvins or degrees Celsius: The calorimeter constant is usually presented in units of joules per degree Celsius (J/°C) or joules per kelvin (J/K). Every calorimeter has a unique calorimeter constant.
