(U, E) Compare with enthalpy and energy. Internal energy (U) is defined so that changes in internal energy (U) are equal to the heat absorbed or released by a process running at constant volume. While changes in internal energy can be measured using calorimetry, absolute values of internal energy usually cannot be determined. Changes in internal en...

The motion and the direction of the brain as it receives, processes, and stores data in response to a odd, irresolvable stimuli. For example, optical illusions, literary ambiguity, and puns all have some kind of internal energy.

In thermodynamics, the internal energy is one of the two cardinal state functions of the state variables of a thermodynamic system. It refers to energy contained within the system, while excluding the kinetic energy of motion of the system as a whole and the potential energy of the system as a whole due to external force fields. It keeps account o...

Energy stored in a body in the form of kinetic energy of molecules and atoms or potential energy of its molecules and atoms due to their mutual interactions. Internal energy, U, is the sum of the kinetic and potential energies of all the particles making up a body but does not include the kinetic an...

that part of the total energy of a physical system that depends only on the internal state variables such as temperature, pressure, volume, masses or amounts of substance NOTE - The internal energy is a function of state equal to the difference between the total energy and the sum of the macroscopic kinetic and potential energies of the system.

when heat is added to a thermodynamical system, it is stored as internal energy. A system cannot contain heat, since heat is a process. See also heat. At equilibrium, U is not necessarily a minimum for thermodynamical systems. See also enthalpy

a function of thermodynamic variables, as temperature, that represents the internal state of a system that is due to the energies of the molecular constituents of the system. The change in internal energy during a process is equal to the net heat entering the system minus the net work done by the system. Symbol: U
