Molecules above absolute zero emit thermal radiation in the form of photons due to their kinetic energy and molecular vibrations. When a substance gains energy, its molecules vibrate faster, increasing temperature and leading to the emission of electromagnetic radiation. The source of these photons is not limited to individual molecules but arises from the collective behavior of charged particles within the material. The electromagnetic fields generated by the random movement of these particles are responsible for the radiation emitted.
PREREQUISITESStudents and professionals in physics, materials science, and engineering, particularly those interested in thermal radiation and molecular behavior at varying temperatures.
If radation is zero, the molecules do not radiate photons, so the questionZaya Bell said:if heat lost through any other means but radiation is zero
appears a bit strange. Can you elucidate ?Zaya Bell said:how exactly do these molecules radiate photons?
I'm saying that all other forms except radiation is zero.BvU said:If radation is zero, the molecules do not radiate photons, so the question
It is said that all molecules above absolute zero emit thermal radiation which are actually photons. The question is, what is the source of the this photons? From the electron? nucleus? Where? And how?BvU said:appears a bit strange. Can you elucidate ?
Ah, I misread, sorry.Zaya Bell said:I'm saying that all other forms except radiation is zero.
correct -- up to a point: individual molecules do not have a temperature. They have velocities and thereby kinetic energy. The temperature of a macroscopic quantity of material has a temperature that is directly related to the average kinetic energy.Zaya Bell said:It is said that all molecules above absolute zero emit thermal radiation which are actually photons.
any phenomenon that can absorb energy (e.g. molecular vibrations, rotations, electron orbits) to go into a state of higher energy can emit energy and end up in a lower energy state.The question is, what is the source of the this photons? From the electron? nucleus? Where? And how?
The electromagnetic fields within the material are constantly changing because they are produced by the random movement of trillions of trillions of charged particles in the heated material. These changing fields are what causes the electromagnetic radiation.Zaya Bell said:The question is, what is the source of the this photons? From the electron? nucleus? Where? And how?
Yeah, sorry. Wanted to say all molecules in a material above absolute zero.BvU said:individual molecules do not have a temperature.
