Scientists began to research thermodynamics in the nineteenth century in order to describe the operation of steam engine and to find its maximum accomplishment. The engines were created by Thomas Savery in 1697 in England and Thomas Newcomen in 1712. These engines opened a new window of Engineering The word thermodynamics for the very first time was used by Lord Kelvin in his publications. The first textbook of thermodynamics was published by a professor of University of Glasgow named William Rankine in 1859. |
The word Therm means heat hence thermodynamics means the power developed from heat. Thermodynamics can easily be defined as science of energy.
Laws of Thermodynamics
Heat engine and steam engine were its initial examples. The principles for the heat engine have been generalized and are called first and Second law of Thermodynamics, since these laws have no proof in the mathematics their validity lies in the absence of contrary experience. Thermodynamics basically links with mechanics and electro-magnetism in its primitive laws.
The first and second law of thermodynamics gives a mathematical deduction and lead to a network of equation. These equations are applied in all the branches of science and engineering. The Chemical engineer meets wide variety of problems such as the calculation of heat and work requirements for physical and chemical process and finding out equilibrium conditions for chemical reaction and for the transfer of chemical species between phases.
