This question is about calorimeter constant. Does the lower the calorimeter constant mean the better the heat retainment?

I have created a lab to test what calorimeter top has the best heat retainment, in order to determine this I added hot water to cold water and measured the temperature every 30 seconds upto 180 seconds? How I can use this data and the varying temperatures to calculate the calorimeter constant?

Generally, yes.


The "calorimeter constant" is just the specific heat of the calorimeter and its thermal conductivity. An "ideal" calorimeter would have a very low specific heat and zero thermal conductivity because the point is to conserve energy within the system.

One procedure to do this experimentally is detailed here:
