An important application of Thermodynamics and, arguably, the one that had motivated its systematic development in the first place, is Heat Engines. By construction, a heat engine consists of a working body, such as a gas or a mixture of vapor and liquid, that undergoes a cyclic process.

WebThe second law of thermodynamics has a wide range of applications, which include steam engines, internal combustion engines (petrol and diesel engines), gas turbine engines, and power-producing stations. A power station transfers 5⋅10 12 J of heat from coal and 1.8⋅10 12 J to the environment. WebHeat engine is a device which takes heat as input and converts this heat in to work by undergoing a cyclic process. A heat engine has three parts: (a) Hot reservoir (b) Working substance (c) Cold reservoir A Schematic diagram for heat engine is given below in the figure 8.42. 1. Hot reservoir (or) Source: It supplies heat to the engine.
