Sentences with phrase «condense under gravity»

Not exact matches

When sufficient moisture condenses on the surface of the polyethylene vapor barrier, it runs down the surface of the polyethylene under the action of gravity where it accumulates on the bottom plate of the wall.

So they can not understand heat transfer in our atmosphere unless they understand how real gases expand and condense and move in the fluid medium that these are under gravity, becoming lighter and heavier than air when heated or cooled forming areas of low and high pressure.

Because real gases not only expand and condense when under different pressures, but expand and condense when heated and cooled, so becoming lighter or heavier than «standard air under gravity», they will rise when heated and will sink when cooled.

The gases under high gravity's pressure closer to the surface are being condensed, bringing them closer together there are more of them so their combined weights under gravity are heavier than gases further away from the surface which have expanded becoming lighter because there are less of them taking up the same room, there are fewer of them so weigh down less heavily on us.

Ideal gas which has no mass therefore no weight under gravity because there is nothing on which gravity can pull; which has no volume therefore does not expand or condense changing its weight under reduced and increased pressure or heat and cold and so does not become lighter or heavier than air under gravity; with no attraction therefore merely capable of bouncing off another and not capable of undergoing chemical changes, such as water and carbon dioxide in the atmosphere forming carbonic acid.
