Sentences with phrase «between air molecules»

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.
