1. Thermodynamics is a branch of physics which deals with the energy and work of a system. Thermodynamics deals only with the large scale response of a system which we can observe and measure in experiments. Small scale gas interactions are described by the kinetic theory of gases. There are three principal laws of thermodynamics which are described on separate slides. Each law leads to the definition of thermodynamic properties which help us to understand and predict the operation of a physical system. We will present some simple examples of these laws and properties for a variety of physical systems, although we are most interested in the thermodynamics of propulsion systems and high speed flows. Fortunately, many of the classical examples of thermodynamics involve gas dynamics.

1. The first low states that "energy of an isolated system is neither created nor destroyed, it remains constant". Energy can be converted from one form to another but not created nor destroyed. You can pass from one form of energy to another, but energy is neither created nor disappears. For example, in a heat engine, the thermal energy of combustion energy can be converted into kinetic energyor into electrical energy. This law allows defining heat as the amount of necessary energy that the system must exchange to compensate for the differences between work done by the system and internal energy.

1. In the first half of the eighteenth century, French philosopher and mathematician Émilie du Châtelet made notable contributions to the emerging theoretical framework of energy by proposing a form of the law of conservation of energy that recognized the inclusion of kinetic energy. Empirical developments of the early ideas, in the century following, wrestled with contravening concepts such as the caloric theoryof heat. In 1840, Germain Hess stated a conservation law (Hess's Law) for the heat of reaction during chemical transformations.This law was later recognized as a consequence of the first law of thermodynamics, but Hess's statement was not explicitly concerned with the relation between energy exchanges by heat and work. In 1842, Julius Robert von Mayer made a statement that was expressed by Clifford Truesdell(1980) in the rendition "in a process at constant pressure, the heat used to produce expansion is universally interconvertible with work", but this is not a general statemen...

1. The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy. The First Law says that the internal energy of a system has to be equal to the work that is being done on the system, plus or minus the heat that flows in or out of the system and any other work that is done on the system,\" said Saibal Mitra, a professor of physics at Missouri State University. \"So, its a restatement of conservation of energy.\"
