Ultraviolet catastrophe.

Previously, you concluded that energy of thermal neutrons at room temperature is the same as electrons because you thought that equipartition theory is still valid in this case. You thought that its validity is a consequence of the conservation of energy.

I think you may have failed to spot the word "average" in the definition.

You thought that its validity is a consequence of the conservation of energy.The type of error that you have made here is comparable with assuming that, since all poodles are dogs, all dogs must be poodles.

Ultraviolet catastrophe is a scenario already accounting for average.
But you don't know which way, for they are not well defined.
You might not think they are well enough defined.But, as I said, the rest of us do.
Why do you keep repeating teh same questions after that have been answered?

You may have heard temperature is just the kinetic energy of molecules, but that's a subtle lie. In this video, Nick Lucid explains those subtlies in the only way he knows how: CRAZY!
This video explains the concepts of temperature and heat, their units of measurement, instruments used to measure them and their main characteristics and behavior with graphic examples.
Misconception about temperature.
This old video describes what became my concern pretty wel
//www.youtube.com/watch?v=sE98Zt1wtLcDifference Between Temperature and HeatQuoteThis video explains the concepts of temperature and heat, their units of measurement, instruments used to measure them and their main characteristics and behavior with graphic examples.Average kinetic energy alone isn't enough to describe temperature, a concept that's supposed to predict heat flow when two objects are allowed to exchange heat. The missing ingredients are what I was trying to identify.
"the faster the molecules vibrate".But the average velocity of a vibrating molecule is zero- it moves left to right, them it moves right to left.On average, it doesn't move at all.
