WebThe efficiency by which a radiator emits radiation, or a solar heater absorbs radiation is decided by its surface texture and colour. The quantity by which this quality is measured is the emissivity. The best possible value for emissivity is 1, which represents the performance of a hole in a hollow body, painted black on its inside. WebYes, Emissivity changes with temperature because of energy that is tied up in the behavior of the molecules that form the surface.
