Homework Statement:: 1. Does the increase in kinetic energy in (for example) water that results from increasing its temperature result from electron excitation (i.e. increasing electron energy levels) or simply increasing their velocity or vibration amplitude/frequency?
2. If excitation is involved, does that mean by definition that gases > liquids > solids in terms of the magnitude of excitation?
3. If the previous 2 are true in relation to excitation, and since electromagnetic radiation is emitted when an excited electron transitions back toward its ground state, is the transmission of heat (i.e. infrared) rays due to the loss of electron excitation?
bonus. If I shine an extremely bright light on a leaf, it will excite electrons on the magnesium in p680 and p700. If I suddenly cut off the light source, for a split second will the p680 and p700 release the same wavelength of light, or could it be changed from input to output?
Relevant Equations:: E = -R/n^2 (and other variations of the Rydberg equation)
E = energy of electron
R = Rydberg unit of energy = 2.18 x 10^-18 J/electron
n = principle quantum number
I was reviewing basic quantum mechanics and couldn't answer these question with 100% confidence when my mind asked them. My current dominant theory is that increasing temperature increases electron excitation, which means that different phases have different excitation ranges. This fits with the fact that lowering an electron's excitation (e.g. by lowering temperature) releases electromagnetic radiation (e.g. infrared). I think this is correct, but I want to make sure I'm not erring in my thought process.
For the bonus I know that the magnesium will try to go back toward its ground state to be more stable. I highly doubt that the released electromagnetic radiation would necessarily be the same wavelength that excited it in the first place, but it would be very interesting if it necessarily was.
