energy transfer
Heat flowing between
Energy transfer is the movement of energy from one object, system, or location to another.
In physics, energy transfers through various mechanisms—heat conduction, radiation, mechanical work, electrical current.
The energy transfer from the sun to Earth sustains all life.
The concept applies wherever energy changes hands: Energy transfer in the food chain moves from plants to herbivores to predators.
