Energy is defined as an exclusive driving force for all physical and chemical changes. Energy exists in many forms such as heat, mechanical work, light, sound, electric, and chemical energy. Energy can be transferred through heat flow, like when a pot of water is put on the stove and the water gets hotter. Something happened here and something changed, hence a driving force for a physical and chemical change. It is important to know that energy does not have mass of a definite shape and these characteristics make it hard to identify. When energy is absorbed temperature rises, therefore, when energy is lost it causes temperature to decrease. Energy also causes the release of electromagnetic radiation melting, vaporization, crystallization, …show more content…

One of the most important things in caliometry is the caliometer. This is a device used to measure the quantity of heat in a reaction. There are many different types of caliometers, some are used to measure the heat capacity of materials, and others measure the aspects the heat generates by new or untested reactions, heat of combustion and burn rates. One type of caliometer is reaction caliometers. These measure heat energy released or absorbed during a reaction that occurs inside the caliometer. Bomb caliometer are used to measure heat of combustion of a particular reaction. Differential scanning caliometers heat flow into a sample is usually measured differentially. A popular caliometer used in biochemistry is called the isothermal titration caliometer. In this caliometer the heat of the reaction is used to follow a titration experiment. It is used in biochemistry because it t facilitates determination of substrate binding to enzymes. Other caliometers that are sometimes used are x-ray micocaliometer, and high-energy particle caliometer. These two caliometers are not as often used, but can still be included in the different types. It is apparent that there are many different types of caliometers and some are used more commonly than others

In this essay, the author

  • Explains that energy is an exclusive driving force for all physical and chemical changes. it can be transferred through heat flow, like when a pot of water gets hotter.
  • Explains that thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy and how it affects matter.
  • Explains that calorimetry is the science of measuring the amount of heat. it is based on endothermic and exotherm measurements.
