The energy in a system arising from the relative positions and interactions of its parts.
〔物理〕内能
Example sentencesExamples
In still air, as internal energy is conducted from a warmer body to the surrounding air, the air near the object is warmed.
Thermodynamics is the study of the inter-relation between heat, work and internal energy of a system.
Atoms give up excess internal energy by giving off photons as electrons return to lower energy orbits.
Temperature is a measure of the internal energy of a system - which contains both kinetic and potential energy.
If all you know of this system is that its internal energy is E and its volume is V, then clearly there are many, many different states the system could be in.
