Sentences with phrase «because water droplets»

Because water droplets like to be circular, the clam - shaped beads tend to have surface tension (known as Laplace pressure) that forces them back into the circular shape.

Over land, the small size of these aerosol particles tends to suppress rainfall because the water droplets that condense on them are light enough to remain aloft.

Now Yanlin Song and his team at the Chinese Academy of Sciences, Beijing, have shown that this frost repellency arises because water droplets...

Not exact matches

* We think this might be because an oil droplet was trapped inside a food colouring droplet and sank, but as the edges of the food colouring droplet diffused into the water suddenly the drop became lighter than the surrounding water (thanks to the less dense oil at the centre) and floated upwards quickly...

Public bathrooms are terrible places to pump for a lot of reasons, not the least of which is because a toilet sprays an aerosol «plume» of microscopic water droplets tainted with urine and fecal matter whenever it is flushed, and nobody wants any of that getting near breastmilk.

Water droplets roll off lotus leaves partly because of the roughness of their surface on the nanoscale.

But because the scales tilt about 30 degrees upwards from the wing surface, they act like springs, bouncing away water droplets that land on them.

Atmospheric scientists believe that such particles make rain less likely, because they spread the available water among many smaller droplets that stay afloat in the cloud.

Because of the force of surface tension, water droplets are normally held in tight spheres.

That's because, like other researchers, Ristenpart believed that oppositely charged water droplets would attract each other and form larger drops.

Because the silica particles attract water, «when you put a droplet on that surface, the water is drawn into these pores instantaneously and wicked away into a uniform sheet,» Rubner says.

Or take the Greek alcohol ouzo — it turns cloudy white when you add water, because it's an emulsion of tiny droplets of oil (the alcohol) destabilized by the water molecules.

Tornadoes are visible because moist air condenses into water droplets.

Because of their near - spherical shape, the droplets meet the surface at a high angle — above 150 ° if the water is sitting on a superhydrophobic surface.

Indeed, conventional wisdom held that higher levels of aerosol pollution in the atmosphere should cool the earth's climate because aerosols can increase cloudiness; they not only reduce precipitation, which raises the water content in clouds, but they also increase the size of the individual water droplets, which in turn causes more warming sunlight to be reflected back into space.

«Although surface engineering facilitates effective liquid manipulation and enables water droplet self - transportation on synthetic surfaces, self - transportation of oil droplets posed a major challenge because of their low surface tension,» explains Postdoctoral Researcher Xuelin Tian.

Still, Chen said, their model is useful because not much is known about how those water droplets impinge on aircraft.

Because air motions in these clouds are driven primarily by processes tied to the presence of liquid, when water droplets competing for water vapor lose to ice crystals, an ensuing chain of events drives the cloud toward collapse.

Because stomata of the plant usually close at night, water can squeeze out at the edges and tips of leaves, gathering in droplets.

This is because when water touches the screen, the touchscreen does not work until you wipe off all of the droplets, this new update negates you having to do that.

This is because as water vapour turns to water droplets and / or ice it releases comparitively huge amounts of heat energy.

a) decreases («dimming») until the 1980s, because atmospheric pollutants (aerosols) make the atmosphere more reflective and also clouds, by increasing the number of water droplets in the clouds, which in turn increases the amount of sunlight reflected, and subsequent

Water droplets and ice crystals are usually treated separately from aerosols because of their different nature.

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 drBecause 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 drbecause 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.

If just 1 % or even just half a percent of DWLWIR never reaches the oceans because it is blocked by very fine water droplets of spray and spume and is carried upwards into the atmosphere (rather than reconnecting with the oceans), then long term (over millions of years) the gross energy budget falls out of balance.
