Detergents are another class of surfactants, and will physically interact with both oil and water, thus stabilizing the interface between the oil and water droplets in suspension.

If the indoor air is very humid, rather than moderately so, water will first condense in small droplets and then freeze into clear ice.

As the droplets rise and the temperature goes below freezing, they become supercooled water and will freeze on contact with condensation nuclei.

If the droplets become too large and heavy to be kept aloft by the air circulation, they will fall from the cloud as rain.

Water vapour will condense into droplets depending on the temperature.

In areas with a lot of small particles in the air, from human pollution or natural sources like dust, the water droplets are likely to be able to freeze at a temperature around, but in very clean areas, where there are no particles ( ice nuclei ) to help the droplets freeze, they can remain liquid to, at which point even very tiny, pure water droplets will freeze.

There may also be practical limitations in using wet steam, as entrained condensation droplets will damage turbine blades.

Individual water droplets exposed to white light will create a set of colored rings.

If a cloud is thick enough, scattering from multiple water droplets will wash out the set of colored rings and create a washed out white color.

However, if the warm layer completely melts the precipitate, becoming rain, the liquid droplets will continue to fall, and pass through a thin layer of cold air just above the surface.

* More monomer from the droplets diffuses to the growing particle, where more initiators will eventually react.

The risk of surface contamination is low, as the droplets will burn up completely in the upper atmosphere on re-entry and the argon, a chemically inert gas, will dissipate.

After 45 to 60 days, droplets of moisture will appear on the shell and the shell will begin to shrink and partially collapse.

An absorbent paper surface, uncoated recycled paper for instance, will allow the droplets of ink to spread ( dot gain ), and so requires a more open printing screen.

Without ice nuclei supercooled liquid water droplets can exist down to about, at which point they will spontaneously freeze.

If there are few ice nuclei compared to the amount of SLW, droplets will be unable to form.

As particles group together to form water droplets, they will quickly be pulled down to earth by the force of gravity.

The droplets would quickly dissipate and the cloud will never form.

If saturated steam is reduced in temperature ( whilst retaining its pressure ) it will condense to produce water droplets, even if it is still considerably above the boiling point of 100 ° C at standard pressure.

With sufficient compression, flow, and heat removal, eventually droplets of liquid air will form, which may then be employed directly for low temperature demonstrations.

Hail growth becomes vanishingly small when air temperatures fall below as supercooled water droplets become rare at these temperatures.

If the cloud droplets continue to grow past this size, they become too heavy to be held aloft as the gravitational force overcomes the atmospheric drag, and they fall from the cloud as rain.

This had the advantage of never " flooding " the engine, as any liquid fuel droplets would fall out of the carburetor instead of into the intake manifold ; it also lent itself to use of an oil bath air cleaner, where a pool of oil below a mesh element below the carburetor is sucked up into the mesh and the air is drawn through the oil-covered mesh ; this was an effective system in a time when paper air filters did not exist.

# Falling droplets of ice and rain become electrically polarized as they fall through the earth's magnetic field ;

This airborne moisture condenses in the spines and leaves of the vegetation, droplets that fall to the ground and irrigate the plants ' roots.

As the droplets fall, they collide with other droplets and become larger.

If the updraft is strong enough, the droplets are held aloft long enough to become so large they do not melt completely, and fall as hail.

If enough water vapor condenses into cloud droplets, these droplets may become large enough to fall to the ground as precipitation.

The droplets entered the space between the plates and, because they were charged, it could be made to rise and fall by changing the voltage across the plates.

Fog consists of very minute droplets of liquid, primarily held aloft by isostatic motion ( in other words, the droplets fall through the air at terminal velocity, but as they are very small, this terminal velocity is very small too, so it doesn't look to us like they are falling, and they seem to be held aloft ).

Large droplets form and fall over the period of about a decade.

Lapilli are spheroid, teardrop, dumbbell or button-shaped droplets of molten or semi-molten lava ejected from a volcanic eruption that fall to earth while still at least partially molten.

The charged droplets then fall through an electrostatic deflection system that diverts droplets into containers based upon their charge.

On every round, droplets fall down from the ceiling and flow through the level.

The droplets that fell from the grate were of relatively uniform size, and the fall provided enough time for the liquid-metal droplet to form into a sphere before landing in the water below.

In warm clouds, larger cloud droplets fall at a higher terminal velocity because the drag force on smaller droplets is larger than on large droplets.

Strong convection upcurrents may allow the droplets to grow to nearly. 08 mm (. 003 in ) before precipitating as heavy rain from an active thundercloud.

In the absence of nucleation sites, tiny droplets must form before they can evolve into larger droplets.

Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids.

Larger molten particles have the fission products diffused through the outer layers, and fused and non-melted particles that were not heated sufficiently but came in contact with the vaporized material or scavenged droplets before their solidification have a relatively thin layer of high activity material deposited on their surface.

In flame atomisation the sample is first converted into fine mist consisting of small droplets of the solution. This is done using a neubulizer assembly. The sample is aspirated into a spray chamber by passing a high pressure stream consisting of one or more cumbustion gases which are passed at the end of the capillary tube immersed in the sample. The impact of the sample with a glass impact bead produces an aerosol mist. The aerosol mist mixes with cumbust gases in the spray chamber before passing to the burner, where the flame thermal energy desolvates the aerosol mist towards dry aerosol particles.

As the tip material fuses, the rapid rod rotation throws off tiny melt droplets which solidify before hitting the chamber walls.

Just before the stream breaks into droplets, the flow passes through a fluorescence measuring station where the fluorescent character of interest of each cell is measured.

When no CCNs are present, water vapour can be supercooled below 0 ° C ( 32 ° F ) before droplets spontaneously form ( this is the basis of the cloud chamber for detecting subatomic particles ).

In above freezing temperatures the air would have to be supersaturated to around 400 % before the droplets could form.

" The novel notes its " Veined-marble arches with flanking fire-fountains ... spewed feathery arcs of perfumed oils ; blue flames consumed much of the fuel before the droplets fell into the lozenge-shaped reflecting pools.

If the cold air layer is too thick, the droplets refreeze before hitting the ground and form ice pellets which are less hazardous.

The amount of solar radiation reaching the ground, as well as the formation of cloud droplets occur on the molecular scale, and so they must be parameterized before they can be included in the model.

These proteins serve as effective nuclei to initiate the formation of ice crystals at relatively high temperatures, so that the droplets will turn into ice before falling to the ground.

In flashing, vapor carries over droplets of brine which have to be separated before condensing, otherwise the distillate vapor would be contaminated with salt.

There is an elevated risk when the intermediate or master stamp contains depressions ( which are especially easy air traps ), or when the imprint resist is dispensed as droplets just before imprinting, rather than pre-spun onto the substrate.
