Calorimeter Constant Calculator

Did you calculate the calorie meter constant? 3

If 40 ml of water at 60 ° C is added to 40 ml of water in one calorimeter at 25 ° C and the temperature rises to 15 ° C, what is the calorimeter constant (Cc)? Thank you very much for your help.

We need to find the difference between the heat lost from water when it rises from 60 C to 40 C and when it is heated from 25 ° C to 40 ° C needed to cool the water. We have to find the difference between the heat.

Losing water:

dH = mC dT

dH = 40 grams (4,184J / gC) (60C 40C)

DH = 3347.2 joules

In cold water is:

dH = mC dT

dH = 40 (4,184) (15C)

DH = 2510.4 joules

Calorie meter rest works:

3347.2 2510.4 = 836.8 joules

Determine the calorimeter's heat capacity:

836.8 joules / 15 اضافہ C increase in temperature = 55.79 joules / centigrade
