Where mcw the mass of cool water originally in the calorimeter,∆T is the temperature increase
Of the water and the calorimeter(∆T),Mhw is the mass of the added hot water and ∆T
Is the temperature decrease of the added hot water. These four quantities are all measured in the
Experiments. If we also know the mass heat capacity of water(c) we can determine
the product(m) for the Styrofoam cups and thermometer, which we will call the calorimeter
constant K (in joules per degree Celsius).
A second experiment is then out by adding a heated metal instead of hot water to the
Water in the calorimeter. We can write an equation similar to eq. (3) to describe the enthalpy change
In this experiment:
