Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...

In the laboratory a "coffee cup"
calorimeter, or constant pressure calorimeter, is
frequently used to determine the specific heat of a solid, or to
measure the energy of a solution phase reaction.
Since the cup itself can absorb energy, a separate experiment is
needed to determine the heat capacity of the calorimeter. This is
known as calibrating the calorimeter and
the value determined is called the calorimeter
constant.
One way to do this is to use a common metal...
