WebTools HyperPhysics is an educational website about physics topics. The information architecture of the website is based on HyperCard, the platform on which the material was originally developed, [1] [2] and a thesaurus organization, with thousands of controlled links and usual trees organizing topics from general to specific. WebDec 28, 2024 · The equation shows that if the volume doubles, for instance, the pressure has to reduce by half in order to keep the equation balanced, and vice versa. The full ideal gas law is PV=nRT P V = nRT where n is the number of moles of the gas, R is the universal gas constant and T is the temperature. The behavior of a Carnot engine or refrigerator is best understood by using a temperature–entropy diagram (T–S diagram), in which the thermodynamic state is specified by a point on a graph with entropy (S) as the horizontal axis and temperature (T) as the vertical axis (Figure 2). For a simple closed system (control mass analysis), any point on the graph represents a particular state of … klip joint hawthorne

WebNov 29, 2009 · "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.

According to the second law of thermodynamics, heat cannot spontaneously flow from a colder location to a hotter area; work is required to achieve this. An air conditioner requires work to cool a living space, moving heat from the interior being cooled (the heat source) to the outdoors (the heat sink).
