But in the Earth's atmosphere, the typical collision time
between air molecules is less than a millionth of a second.
Not exact matches
Because the carbon atoms in a C36 fullerene must strain to form a sphere, the bonds
between atoms are brittle; thus, the
molecule is very reactive and quickly decomposes in
air.
The team thinks one reason their technique is so efficient is that a chemical reaction
between the hydrogen plasma and
air molecules in the chamber's atmosphere generates cyano radicals — carbon - nitrogen
molecules that have been stripped of their electrons.
Physicists at the University of Washington have conducted the most precise and controlled measurements yet of the interaction
between the atoms and
molecules that comprise
air and the type of carbon surface used in battery electrodes and
air filters — key information for improving those technologies.
Water
molecules are more attracted to each other than to
air molecules and form a spherical shape to maximise contact
between water
molecules, which leaves as few as possible exposed to the
air.
In order to equalize the pressure difference
between the the rising parcel and its new environment,
air molecules inside the higher - pressure
air parcel push out the sides of the parcel.
And so some more do move downwards than upwards, and thus the lower half ends up warmer, because
air molecules which move there gain KE at the expense of PE as they move
between collisions.
But below about 1,500 meters, the ice becomes so compressed that trapped
air molecules are forced into the space
between the ice crystals, forming what is known as a gas clathrate.
If he means the temperature of individual
molecules, then thermal equilibrium in the «silver wire experiment» has already been achieved (
between the top and bottom of the
air column).
This means that the average length of time
between collisions amongst the
air molecules will increase.
Adding the influence of water vapor concentration to the density profile makes the difference
between the densities of the two cases a little larger, because water vapor lowers the density as H2O
molecules are lighter than average for dry
air.
The notes on this point are self - contradictory: This derivation of [CO2](t) does not assume any given equilibrium
between ingress and egress...» ANSWER: the only assumption made is that absorption is proportional to the CO2 content of the
air; it applies equally to the both parts or sets of
molecules of the
air, the anthropic (24 ppm) and the natural (376 ppm); this makes NO hypothesis about ingress»
«Here on Earth, environmental heat is transferred in the
air primarily by conduction (collisions
between individual
air molecules) and convection (the circulation or bulk motion of
air).»
That means that the amount of energy required to break the bonds
between water
molecules is 5 times greater than the energy required to warm the
molecule to a point where it will evaporate (assuming that the
air is unsaturated).
The term «ocean skin» is rather a misnomer because in reality the area of interaction
between air and water is a haze of mixed water and
air molecules in constant dynamic interaction.
So to argue for the insignificance of the thermosphere to radiative balance it is not sufficient to point to its small mass and number of
molecules — one must accompany this with physics showing for instance the mean free path of photons
between interactions with
air molecules to be sufficiently long that the thermosphere will not significantly affect outgoing flux.
Because of the different intramolecular forces
between water
molecules as vapor in
air, water, and ice, the wavelengths of emission and absorption are shifted; some of the radiation from the water / ice droplets at the top of a cloud can escape to space because the atmosphere above it is transparent at its wavelengths, whereas the same radiation from droplets at the bottom of a cloud will be absorbed and re-emitted in random directions from the droplets above, including back down to the originating droplets.
This setup regulates the electrical charge via those outer plates, moving the inner material back and forth
between positive and negative to vibrate the
molecules in the
air and create sound waves.
