Heat Capacity vs. Specific Heat

Postby bonnie_schmitz_1F » Wed Feb 06, 2019 8:58 pm

Why in finding the heat capacity of the calorimeter do we ignore n in the equation q = nC∆T? I think it has something to do with heat capacity vs. specific heat but I'm not sure.

Yes, you are finding the heat capacity of the calorimeter, whereas that equation corresponds to molar heat capacity. As such, you can ignore the mass of the calorimeter and just use C=q/delta T

The equation "q = nC∆T" refers to the molar heat capacity because it measures the heat required to raise 1 mol of a substance by 1 degree celsius. We can ignore the "n" in the equation for the calorimeter because we are looking for the heat capacity instead.
