Why do most people expect that anything that emits light has to be hot?

Answer 1

when things gain energy, their particles heat up and begin moving, but what also happens is that the electrons in the substance are given enough energy to jump energy levels. This is unstable, so they fall back down to their ground state and give off energy in the form of light (red hot, white hot).

Answer 2

Because hot things do emit light in the infared spectrum range.

Cold light emitting reactions or processes are uncommon.

Answer 3

Our first experience with something that emits light was with the sun , which is hot. Then fire is also hot and gave off light. Thus, we associate things that gave off light with hotness from experience.
I think that tendency is call stimulus generalization in psychology.

Answer 4

Because since the time that Man has come to control or know light, it has always been associated with heat.

Answer 5

Isn't light caused by exited electrons/transfer of electrons? And usually the more electrons exited, the more energy created, thus, more light (and heat)?

My science is a bit rusty...

Answer 6

because usually it is, and when youthink of bright light the first thing I think of is the hotter than hell sun!
