EXPERIMENT No.1
CALORIMETRY(VIRTUAL)
OBJECTIVES
• To carry out basic calorimetry experiments.
• To compute the specific heat of an unknown metal using calorimetry results.
• Calorimetry measurements were used to determine the heat of reaction (H).
INTRODUCTION
The two most prevalent ways for a system to exchange energy with its environment are heat and
work. In reactions that do not involve gases, the work term is zero, therefore all of the energy change is
converted to heat. Calorimetry is a technique for determining the quantity of heat that flows into or out of
the environment (heat measurement). An insulated container, a thermometer, a mass of water, and the
system to be investigated make up a calorimeter. To put it another way, we can say that the thermodynamic
universe is made up of the system and the water that surrounds it. We'll put this theory to the test in the
experiment.
Calorimetry is a technique for determining how much thermal energy is transmitted during a chemical
or physical reaction. This necessitates meticulous monitoring of the temperature change that occurs during
the operation, as well as the masses of the system and its surroundings. The advantage of calorimetry is that
it is fully non-specific, which means that it may be used to measure practically any form of biological
reaction or activity. The instrument's sensitivity could be the limit.
Calorimetry is a vital tool in biological research. Calorimetry is a frequently used chemical reaction and
biochemical reaction measurement method. The fundamental benefit of calorimetry is that it does not
require complicated equipment and can monitor very small energy changes. Calorimetry can be applied in
a variety of fields, including life science, clinical medicine, pharmacology, biotechnology, ecology,
environmental research, and many more.
