Sentences with phrase «air molecules slow»

Collisions with air molecules slow a falling penny.

Not exact matches

Even though 310 miles up is technically outer space, a few air molecules still float around — not enough to make the slightest difference to astronauts on a space shuttle or the space station, which orbit considerably lower, but sufficient to slow the GRACE satellites perceptibly.

If the radiation from one molecule of carbon dioxide in every 2,500 air molecules could actually slow the rate of cooling of Earth's surface, then the radiation from water vapour should slow the cooling at least a hundred fold, making rain forests about 50 degrees hotter than dry regions at similar latitudes and altitudes.

So water dances at many speeds, from the unimaginable fast vibrations of its molecules responding to thermal infrared radiation, to the moment - to - moment dance of its phase changes in response to temperature changes, to the week - long dance of its vapor in and out of the atmosphere, to the slow geological pavanes of rock, air and life, of which it too forms an inextricable part.

In a column of air under a gravitational field which, unlike our atmosphere, is in thermal isolation, the quicker molecules will tend to rise higher and lose some of that velocity (or energy) and the slower ones will fall and gain velocity.

We assumed only that due to the biological and physical effects the ratio fabsorbed (t) / (total CO2 content of then air) is more or less constant, hence a simple response pulse response exp -LRB-- t / lifetime) is applied to the anthropic time series of coal, gas, oil and cement which have different delta13C As the isotopic signature of (CO2 natural)(t) is slowly decreasing because plants living days or centuries ago are now rotting and degassing and as molecules entered in the ocean decades ago are now in the upwellings after a slow migration along the equal density surface from the high latitudes where those surface are surfacing at depth zero, there are common sense constraints or bounds on the possible evolution of the delta13C of the natural out - gassed CO2 molecules.

The fact that air movements are mainly near horizontal rather than vertical slows down the adiabatic lapse rate considerably thus keeping the air molecules closer together for longer — It is also likely that temperatures would be cooler without Water Vapour.

Back radiation does not slow evaporative cooling of a warmer water body, or slow the rate of conduction into air molecules at the surface - atmosphere boundary.
