Sentences with phrase «air molecule collides»

When a «hot» air molecule collides with a CO2 molecule, it can also cause the CO2 molecule to vibrate faster, and the CO2 can emit this additional energy as a photon.
When an air molecule collides with the CO2 molecule the vibrational energy is converted to kinetic energy and the air molecule is now hotter, while the CO2 molecule returns to its ground state.

Not exact matches

It channels some of these particles toward the poles, where they can collide with air molecules and release energy in the form of light, producing brightly colored auroras.
The team concludes that these signals are generated by speeding electrons produced when cosmic rays collide with molecules in the air (Physical Review Letters, DOI: 10.1103 / PhysRevLett.105.151101).
In what Grashorn calls a «serendipitous discovery», his team has worked out that these signals are generated by speeding electrons produced when cosmic rays collide with molecules in the air.
The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each other at speeds of hundreds of miles per hour.
When those relativistic electrons collided with air molecules, they generated gamma rays and lower energy electrons that were the main electric current carrier that produced the strong radio pulse before the visible lightning.
Dark lightning is a burst of gamma rays produced during thunderstorms by extremely fast moving electrons colliding with air molecules.
Fragments fly out from this collision and collide with more air molecules, in a cascade that continues until the energy of the original particle is spread among millions of particles raining down upon the earth.
Once this mixture of fuel droplets, and air is inside the cylinder, and a spark occurs do the air molecules gain kinetic energy, then collide into the atomised fuel, and the individual fuel molecules break apart thus turning fuel from a liquid to a gas (vaporisation), then those fuel molecules combines with the air molecule, then combustion occurs?
Almost immediately (nanoseconds) they relax from their excited state by either 1) emitting that energy as a new photon, some of which will continue up towards space, some of which will go back downward to be reabsorbed, thus keeping the energy in the atmosphere longer, or 2) by colliding with another gas molecule, most likely an O2 (oxygen) or N2 (nitrogen) molecule since they make up over 98 % of the atmosphere, thereby converting the extra vibrational energy into kinetic energy by transferring it to the other gas molecule, which will then collide with other molecules, and so on, making the air warmer.
As you say, convection uses up a lot of energy too and also counters the idea of radiative heat transfer as a big ticket item because «hot» CO2 molecules only remain so for a brief fraction of a second before they collide with N2 or O2 to warm that localised parcel of air; which then rises to attain equilibrium T somewhere higher and at a COLDER temp so no rad Transf!!!
It follows that a gazillion molecules doing this in a column, perfectly vertically without ever colliding with each other, would produce a column of air which is hotter in the lower half than the upper.
Thermalized means the GHG molecule collides with a non-GHG molecule in the air, converting the photon to kinetic energy, which can now be seen on a thermometer.
Either of these GHGs will gain energy if they absorb IR from the ground (or from GHGs in the atmosphere), but then when they collide with other molecules (almost always N2 or O2) they will give away that extra energy until they are at the same average energy as the rest of the air.
Yes, pairs of N2 - N2 and O2 - O2 do present in air at normal pressure and temperature when all molecules collide in gaseous mess.
