Reference: AQA
Energy is spread out to the surroundings, too thinly spread to be recovered, as when friction in the bearings transfers energy into the thermal store of the parts and the air.
Energy transferred to the thermal store of the surroundings as the wasted share, by resistance in the wires and friction in moving parts.
In all system changes, energy is dissipated so that it is stored in less useful ways.
The transfer of energy to the surroundings, often as wasted thermal energy.
