sree asked in Science & MathematicsPhysics · 1 decade ago

does an atom of any element change to electromagnetic waves when heated to a high temperature.?

does the electrons revolve around the nucleus when it gets more energy as it is heated to a very high temperature.if it revolve so does the characters of the atom changes to that of an electromagnetic wave.

    The atom does not change (at 'normal' temperatures). However, the electrons become more energetic and move to higher orbits around the nucleus.

    As the electron 'cools', it drops to a lower orbit and emits energy waves, some in the visual spectrum. That's how ordinary electric lights work.

    I am not aware of such a theory. There are two things I can say about electrons, heat and electromagnetic energy:

    1. Accelerated electrons emit electromagnetic energy. This is generally why if you apply an alternating voltage source to a wire it generates alternating current which accelerates the electrons within the wire and transmits electromagnetic energy.

    2. Heat applied to matter can ionize it if the thermal energy is high enough. It means that virtually all electrons will become free from the nuclei gravitational force.

    Hope this helped

    Heat will get electrons to higher levels of energy, thus higher orbits.

    Electron movement definately creates an electromagnetic wave which will increase as the energy increases as well.

    BUT, the atom structure itself will not change other than the electrons moving further from the nucleus and they will go back to their original orbits once the temperature drops.
