When a photon is absorbed by a molecule what happens to the photon?

The photon is adsorbed in the first atom that it encounters. the atom then retains the energy for a finite period of time, and then ejects it as a photon, in the frequency of the atom. The larger the atom, the lower the freq. so, a lot of the re-raidation occurs in the IR band (heat) A good example of this, is the UV photons impinging on (or into) your skin. the result (not incliuding the celluar damage) will be felt as heat. and if continued long enough, a burn will result. Want More proof?, try a UV laser. Dr. B

All of them fluorescence, light, and heat.

In theory what happens to water at absolute zero should it constantly expand to this point?
Einstein calculated that at absolute 0 the water molecule turns into photon
What happens to water that is not absorbed by soil?
Rivers & oceans.
What is the highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization?
yes , the electron in the ground state of the hydrogen atom will absorb a photon of energy 13.6ev but not greater than 13.6 ev . because 13.6 ev is the energy which excites the hydrogen atom
What happens to heat during an endothermic reaction?
Heat is absorbed.
What happens when a molecule combusts?
Combines with oxygen
What happens when a photon hits a chlorophyll molecule?
Photosynthesis begings
What happens when carbon dioxide absorbs an IR photon?
The molecule vibrate
What happens to a photon when it hits a leaf?
the photon's energy is either reflected green (because its a leaf) or its absorbed red, because red is the opposite of green and the red is not seen.
What happens at the atomic level when light is absorbed?
When an electron absorbs a single photon of light it moves from its current shell to an outer shell.
Why is glass transparent?
When the electrons in molecules are unable to absorb the energy of incident photon, the photon continues along its path. This happens in the case of glass, even though glass is not 100 percent transparent, as some of the photon energy is absorbed by the glass electrons.
An electron gains 5.5 x 10-16 J of energy when a photon is absorbed What is the frequency of the photon that is absorbed?
8.3 x 1017 Hz
What happens when photon is absorbed by atom?
When an atom absorbs a photon its energy is transferred to outer shell electrons. The result will be the transition of an electron to a higher energy state.
When hydrogen bonds break what happens to energy?
energ y is absorbed by the molecule to increase its kinetic energy
What happens when light hits a pigment?
When a chlorophyll molecule absorbs a photon of light, Photons strike the "antenna" of the chlorophyll molecule. This causes electrons in the photo-reaction centers that are attached to the antennas to become excited and move to a higher energy level. That's photoexcitation. The valence electrons in Magnesium (part of the chlorophyl molecule) jump to an excited state.
Can a photon be oxidized by an electron from the valence shell of a molecule?
Photons are not oxidized. They are energy. A photon may be captured by an atom or molecule resulting in a change to the state of atoms.
In theory what happens to water at absolute zero should it constantly expand to this point?
Einstein calculated that at absolute 0 the water molecule turns into photon
When matter absorbs a photon what is the relationship between the energy of the matter before and after the absorpion and the frequency and the wavelength of the radiation absorbed?
After the absorption, the matter has added energy equal to 'hf' the energy of the absorbed photon.
