Can we find Practical Applications of Thermodynamic Concepts? Thermodynamics can be defined as the study of energy, energy transformations and its relation to matter. Thermodynamics deals with the transfer of energy from one place to another and from one form to another. The second rule of thermodynamics applies to all refrigerators, deep freezers, industrial refrigeration systems, all forms of air-conditioning systems, heat pumps, and so on. Thermodynamic cycles govern the operation of all forms of air and gas compressors, blowers, and fans. Energy technology and power sector are fully dependent on the laws of thermodynamics. The most common practical application of the First Law is the heat engine. Heat engines convert thermal energy into mechanical energy and vice versa. Gasoline and diesel engines, jet engines, and steam turbines that generate electricity are all examples of heat engines. Thermodynamics has very wide applications as basis of thermal engineering. The most useful application of the third law is the computation of absolute entropies of pure substances at temperatures other than 0K from their heat capacities and heats of transition.
