Calorimetry is one of the oldest areas of physical chemistry. The
date on which calorimetry came into being may be taken as 13 June
1783, the day on which Lavoisier and Laplace presented a
contribution entitled, Memoire de la Chaleur" at a session of the
Academie Francaise. Throughout the existence of calorimetry, many
new methods have been developed and the measuring techniques have
been improved. At p- sent, numerous laboratories worldwide continue
to focus attention on the development and applications of
calorimetry, and a number of com- nies specialize in the production
of calorimeters. The calorimeter is an instrument that allows heat
effects in it to be determined by directly measurement of
temperature. Accordingly, to determine a heat effect, it is
necessary to establish the relationship - tween the heat effect
generated and the quantity measured in the ca- rimeter. It is this
relationship that unambiguously determines the mathematical model
of the calorimeter. Depending on the type of ca- rimeter applied,
the accuracy required, and the conditions of heat and mass transfer
that prevail in the device, the relationship between the measured
and generated quantities can assume different mathematical forms."
