Explanation:
Incident light makes an electron oscillate. The electrons emit light or absorb the light, collide with other electrons, thereby converting light energy to more internal energy. and convert it to heat.
Light wave of a given frequency is incident on a material with electrons having the same vibrational frequencies, then electrons absorb the energy of the light wave and transform it into vibrational motion.
Answer:
Sublimation occurs more readily when certain weather conditions are present, such as low relative humidity and dry winds. Sublimation also occurs more at higher altitudes, where the air pressure is less than at lower altitudes. Energy, such as strong sunlight, is also needed.

Answer:
The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.
Explanation:
The kinetic energy of gas molecule is given by following equation:
Since the temperature (T) is constant for both molecules. Therefore, there kinetic energies will also be the same. Therefore,
<u>The average speed of molecule of oxygen is one-fourth of the speed of the hydrogen molecule.</u>
So the air evaporate s and mix the temptures and marks air power to the same theme as the other the two degrees lower and lower until they are the same
