Is chemical energy internal energy
WebInternal energy is the sum of the kinetic and potential energies of a system’s atoms and molecules. It can be divided into many subcategories, such as thermal and chemical energy, and depends only on the state of a system (that is, P, V, and T), not on how the energy enters or leaves the system.

Internal energy does not include the energy due to motion or location of a system as a whole. That is to say, it excludes any kinetic or potential energy the body may have because of its motion or location in external gravitational, electrostatic, or electromagnetic fields. See more The internal energy of a thermodynamic system is the energy contained within it, measured as the quantity of energy necessary to bring the system from its standard internal state to its present internal state of … See more The internal energy of a system depends on its entropy S, its volume V and its number of massive particles: U(S,V,{Nj}). It expresses the thermodynamics of a system in the energy … See more Thermodynamics often uses the concept of the ideal gas for teaching purposes, and as an approximation for working systems. The ideal gas consists of particles considered as point objects that interact only by elastic collisions and fill a volume such that their See more In addition to including the entropy $${\displaystyle S}$$ and volume $${\displaystyle V}$$ terms in the internal energy, a system is … See more The internal energy $${\displaystyle U}$$ of a given state of the system is determined relative to that of a standard state of the system, by adding up the macroscopic transfers of energy that accompany a change of state from the reference state to the given state: See more The above summation of all components of change in internal energy assumes that a positive energy denotes heat added to the system or the negative of work done by the system on its … See more For an elastic medium the mechanical energy term of the internal energy is expressed in terms of the stress $${\displaystyle \sigma _{ij}}$$ and strain See more WebJan 7, 2014 · Internal energy, U, is the total energy contained in a thermodynamic system. However, absolute internal energy is hard to determine, and even relative internal energy and changes to internal energy are hard to determine. Here's why: Changes to internal energy usually occur through heat transfer q or work done w.
