The complete sentence is:
A calorimeter directly measures changes in temperature in order to calculate specific heat.
In fact, the amount of energy acquired/released by a substance is directly proportional to its change in temperature due to the equation
[tex]Q=mC_s \Delta T[/tex]
where Q is the amount of energy, m is the mass of the substance, Cs is the specific heat of the substance and [tex]\Delta T[/tex] is the change in temperature. Therefore, by knowing Q, m and by measuring the change in temperature, it is possible to calculate Cs, the specific heat capacity of the substance.
