Sentences with phrase «number of molecules per»

ii) In the case of the Ideal Gas Law it is the height of an atmosphere of a given mass that determines the number of molecules per unit of volume at the surface and the more molecules per unit of volume the hotter the surface will become at a given level of solar input.

The molar density of a gas tells you the average number of molecules per cubic metre of the gas.

The number of moles, the mass and the number of molecules per gram are the properties that have a major influence on the mean free path length of photons through the gases comprising the atmosphere.

In the earths atmosphere, pressure, which is related to the number of molecules per unit volume, decreases exponentially with altitude.

If we now consider the number of the stars (15,000 x 106 visible to the optical telescope alone) you will understand how it is possible to say, cosmically speaking, that we are enveloped in a sort of monstrous gas formed of molecules as heavy as the Sun moving at distances from each other so great that they have to be reckoned in light - years (bearing in mind that light travels at a speed of 186,000 miles per second, and that we are only 8 light - minutes distant from the sun)-- a gas made of stars!

Carbon dioxide concentrations in the atmosphere are measured in parts per million, the number of molecules of carbon dioxide there are in every million molecules of air.

As each sequencing glass slide can sequence only a finite number of DNA molecules, higher levels of multiplexing would lead to fewer DNA molecules to be sequenced per sample.

Concentration units are parts per million (ppm) or parts per billion (ppb), indicating the number of molecules of the greenhouse gas per million or billion molecules of air.

You have to look at the absorption crosssection per molecule of CO2 and count up the number of CO2 molecules per unit area that would be in the path of a photon travelling a certain distance in the atmosphere you can understand how such a low concentration of CO2 can have such a large effect.

The number means there would be 950 molecules of carbon dioxide in the air per every million air molecules.

The number means there were 313 molecules of carbon dioxide in the air per every million air molecules.

The number of molecules passing through unit area per unit time multiplied by the average energy carried per molecule.

Ok, don't see where you gave where any of the numbers are coming from but it suffices you seem sure the radiation pressure from added GHG molecules (H2O or CO2), let's say 10 per million is so infinitesimally small that the lift of the atmosphere in every cubic meter per one meter layer up to say 80 km is so insignificant it can be totally ignored.
