Sentences with phrase «of air molecules»

Why would it become heavier if it consists of the same number of air molecules?

The concentration of water vapor in the atmosphere reflects the number of molecules of water compared with the total number of air molecules (mainly nitrogen and oxygen).

Ion concentration is determined by adding the number of ions counted at the molecular ion's mass - to - charge ratio to the number of air molecules in the reaction chamber, which can be identified according to the pressure levels in the reaction chamber.

Cosmic rays, high - energy particles raining down from exploded stars, knock electrons out of air molecules.

A clump of air molecules could fool an observer into thinking that something lies below — perhaps a glacier — so each satellite has what's known as a «proof mass» floating in a chamber inside, untethered to the satellite itself.

But unlike the roars of big cats, the sounds produced by bugs are transmitted through the solid material beneath their feet, usually a leaf, rather than by the vibration of air molecules.

Imagine taking a balloon full of air molecules, somehow tagging them so you could see them and then releasing them into a room with no air molecules, noted co-author and UCSB / Google researcher Pedram Roushan.

To review the dynamical method, we start with the atmosphere and we pretend that none of the air molecules can move — they are fixed in place.

With warm waters in the west and cool waters in the east there is an upward air movement (low pressure systems) in the west and a downward movement (high pressure systems) in the east, leading to a lack of air molecules over the sea surface in the west and an overabundance in the east.

This is a very common error that unfortunately developed some traction on the web in the context of the ozone hole and CFC transport into the stratosphere — «aren't they heavier than the rest of the air molecules, so wouldn't they stay close to the surface?»

Granted we cant provide an exact mathematical model demonstrating that it is «impossible», as everything (including the fact that all of the air molecules in the room within which you are setting now may suddenly all move to one side, leaving you in a vacuum) is «possible».

This minimizes the energy transfer through the movement of the air molecules — in other words, aerogels are highly efficient insulating materials.

«The atmosphere does not collapse under the downward pull of gravity because of the energy embedded in the movement of the air molecules.

However, above the tropopause, some of these air molecules coalesce into large multimers.
