energy equation
11Equation of state (cosmology) — In cosmology, the equation of state of a perfect fluid is characterized by a dimensionless number w , equal to the ratio of its pressure p to its energy density rho;: w=p/ ho . It is closely related to the thermodynamic equation of state and… …
12Equation of state — In physics and thermodynamics, an equation of state is a relation between state variables.cite book | author=Perrot, Pierre | title=A to Z of Thermodynamics | publisher=Oxford University Press | year=1998 | id=ISBN 0 19 856552 6] More… …
13Energy condition — In relativistic classical field theories of gravitation, particularly general relativity, an energy condition is one of various alternative conditions which can be applied to the matter content of the theory, when it is either not possible or… …
14Équation de Kaya — L équation de Kaya relie des facteurs du niveau de production par l Homme de dioxyde de carbone (dans le cadre des interrogations relative à l effet de serre). Elle indique que le niveau total d émission peut s exprimer comme le produit de quatre …
15Energy-momentum relation — In special relativity, the energy momentum relation is a relation between the energy, momentum and the mass of a body:: E^2 = m^2 c^4 + p^2 c^2 , ;where c is the speed of light, E ; is total energy, m ; is invariant mass, and p; is momentum.For a …
16Energy level — A quantum mechanical system or particle that is bound that is, confined spatially can only take on certain discrete values of energy. This contrasts with classical particles, which can have any energy. These discrete values are called energy… …
17Energy cannibalism — Energy portal Energy cannibalism refers to an effect where rapid growth of an entire energy producing industry creates a need for energy that uses (or cannibalizes) the energy of existing power plants. Thus during rapid growth the industry as a… …
18Energy Tax Act — The Energy Tax Act (USPL|95|618, USStat|92|3174, enacted November 91978) is a law passed by the U.S. Congress as part of the National Energy Act. It was a response to three developments::1. large revenue losses associated with the oil and gas tax …
19Energy spectrum — An energy spectrum is a distribution of energy among a large assemblage of particles. It is a statistical representation of the wave energy as a function of the wave frequency, and an empirical estimator of the spectral function. For any given… …
20Energy eigenstates — The Energy eigenstates of a quantum system are the set of eigenvalues and eigenvectors obtained by solving the time independent Schrödinger equation for the system in question,:hat{H}Psi n=E nPsi n:where hat{H} is the time independent Hamiltonian …
