Sentences with phrase «liquid water droplets»

Less well appreciated is that clouds (made of ice particles and / or liquid water droplets) also absorb infrared radiation and contribute to the greenhouse effect, too.

When the relative humidity reaches 100 %, the water vapor condenses into liquid water droplets and the clouds begin to form.

Oddly, it is liquid water droplets that must be present in the air for a plane to accumulate ice: water vapour, snow or ice itself is rarely a problem.

In such a cloud, the growth of a liquid water droplet to a raindrop begins with condensation, as additional water vapour condenses in a supersaturated atmosphere.

Not exact matches

Liquid fertilizer can be added along with the water droplets, minimizing groundwater contamination.

Supercooled water droplets in a cloud can remain liquid at temperatures far below freezing, their surface tension preventing solid crystals from forming.

Unlike traditional pipettes, which draw up liquids using suction, the liverwort relies on the surface tension of the water to hold droplets, says study coauthor Hirofumi Wada, a physicist at Ritsumeikan University in Kusatsu, Japan.

Yet despite being 62 degrees below the freezing point of water, the cloud droplets remain stubbornly liquid.

The phenomenon can be understood through the action of water molecules, which condense to form liquid droplets by sticking to particles like dust and pollen.

«Simply tweaking the water's chemistry made the liquid metal droplets move and change shape, without any need for external mechanical, electronic or optical stimulants.

To work out how to enable liquid metal to move autonomously, Professor Kourosh Kalantar - zadeh and his group from the School of Engineering at RMIT first immersed liquid metal droplets in water.

The procedure, described in the latest issue of the journal Proceedings of the National Academy of Sciences, centers on making droplets, which are a mixture of two or more immiscible, or unmixable, liquids — in this case, oil, water, and alcohol.

These are water droplets coated in a hydrophobic powder, which holds the liquid in place.

The researchers used water and water mixed with glycerin to create a model for predicting the velocity and height of the droplets, or jet aerosols, cast upward as bubbles on a liquid's surface burst.

Even worse, he says, when their surroundings change, stress granules switch from being hydrogels to a different type of structure, called liquid droplets, the same way hair gel might dissolve in water if you heat it up.

«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.

The researchers placed these liquid crystals into water droplets, which in turn were placed in oil, producing an emulsion.

FUS proteins can change back and forth from small liquid droplets (resembling oil droplets in water) to small gels (like jelly) inside nerve cells.

«Probability density function,» a statistical representation of the likelihood of something occurring at any point in time, was used to examine cloud properties, including vertical motion, liquid and ice water content, and the conditions of cloud particle growth, including how ice crystals grow at the expense of liquid droplets.

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.

What makes bijels remarkable is that, rather than just making the spherical droplets that we normally see when we try to mix oil and water, the particles at the interface shape the liquids into complex networks of interconnected fluid channels.

Simultaneously, as the average liquid droplet becomes smaller through evaporation, the vapor's density increases, so more vapor molecules merge at a faster rate to become microscopic liquid droplets, and more water molecules are ionized.

Supercooled water droplets can exist naturally in the upper regions of the planet's atmosphere, but physicists still don't know just how cold liquid water can get.

In the new study, she and her colleagues have now shown that FUS aggregation results from a liquid - liquid phase separation analogous to the gradual coalescence of oil droplets dispersed in an oil - water emulsion.

In the darkened contemporary gallery, one wall was dominated by Magali Reus's wall - sized video projection Highly Liquid (2013), a shower scene mimicking commercials in which close - ups of water droplets splash and roll down a man's chiselled body.

A hydrophilic surface would also be preferable for condensation (reduced surface tension effect for a given mass of liquid water in a droplet), though I've never heard of that being important in the atmosphere.

You can minimize this problem by injecting the CO2 as liquid droplets that float or sink through the water column, spreading out the injection location, or by injecting from a moving ship that drives around.

And do get that CO2 can re-radiate in random direction [which is unlike reflection which requires a surface - btw, droplets of liquid water do have a surface - hence headlights and fog.]

Specific heat of water gas is 1.996 KJ / kgK liquid water is 4.193 KJ / kgK at 10 C And liquid water in form of droplets are in the atmosphere.

A contact nucleus converts liquid water to ice by touching a supercooled water droplet.

The evolution of clouds that follows the formation of liquid cloud droplets or ice crystals depends on which phase of water occurs.

Altogether Water; in its three forms as vapor, liquid droplets, and particles of ice; is the overwhelmingly dominant substance in Earth's climate.

But if somehow enough H20 gas molecules become a liquid droplet of water there some critical amount of molecules - as wild guess, say 1000 molecules formed as liquid water - in which H20 gas can more than just briefly condense onto such a droplet of water.

Or if the there enough water molecule in droplet the water acts similar to a drop water from dripping facet or pool of water - which a portion of it is evaporating and condensing - but with H20 gas molecules in a gas mixture most of gas molecules are transiting from gas to liquid state within a time frame of something like less than a second.

So if water molecule formed with say 5 molecules of H2O liquid droplet, within some period measured in nanoseconds, and if this other gas molecule condensed making 6 molecules, than they may fly apart within nanoseconds or less than a second.

Most of this «thought experiment» is attributed to water vapor (plus liquid droplets and ice crystals), the most abundant GHG by far.

The water droplet can be liquid over a wide range below freezing, that is super-cooled, below freezing.

Current joint measurement projects include assessment of liquid water volume from passive fog collectors (run by scientists at California State University, Monterey Bay, and NASA Ames Research Center), active fog sampling for mercury (run by researchers at the University of California, Santa Cruz), and measurement of droplet size and distribution (run by Georgia Southern University researchers).
