Thermodynamic also study the relationship between energy and entropy, which is related to the heat and work. It is a set of theories related to the macroscopic properties which we can measure (eg, temperature, volume and pressure) for energy and the ability to provide employment. A thermodynamic system is defined as the total mass of waste and identity. Everything outside the system which is separated from the environment and environmental systems at the borders. Some applications of thermodynamics including design:
1) AC and fridge
2) turbo compressor motor
3) steam turbine power plant
4) engines used in airplanes
In the beginning of thermodynamics, which is used to warm up the engine, is working on thermal properties of materials “such as steam, in order to improve efficiency and engine power. Thermodynamics then continued to study energy transfer in chemical processes, such as surveys, published in 1840, of thermal chemical reaction by Germain Hess, who was initially unclear handle the relationship between energy exchange with the heat and work.
