exchange energy
- noun
- Specialized
:
energía de intercambio
- In quantum mechanics, particles can exchange energy when they interact during collisions.
Examples
-
The electrons in the conductor exchange energy with the lattice atoms, affecting the material's temperature.
-
The other process for transporting heat from one body of material to another is to place them into contact so that the particles of one body can collide with and exchange energy with the particles of the other body without the particles themselves being largely moved from their positions.

Remember, we took two systems that are a different temperature and we allow them to exchange energy and entropy.
-
The two masses exchange energy inside the black box, the ground heating and the atmosphere cooling until they reach equilibrium with each other.

Since the gas can't radiate the energy away, and the surface temperature has dropped, the next contact of a gas molecule with the surface will exchange energy in the other direction.

Atoms in a gas exchange energy through collisions, which can lead to changes in speed and temperature.

Morphology
The phrase is compositionally built from 'exchange' + 'energy', so a learner can infer it refers to some kind of energy associated with an exchange process. However, the specific meaning (the quantum‑mechanical 'exchange energy' between electrons) is a technical, domain‑specific sense that is not predictable from the everyday senses of the words, so prior exposure or subject knowledge is needed.
Etymology
Exchange energy comes from the two parts exchange and energy. Imagine tiny particles 'swapping' places or states and that 'swap' changes how they pull or push each other. So exchange energy means the amount of energy that changes because of that 'exchange'.
