Sentences with phrase «supercooled water at»

Not exact matches

The above - wing air expands rapidly and cools to — 40 degrees Fahrenheit, the temperature at which supercooled water turns to ice.

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

The anomalous thermodynamic properties of water point to the possible existence of two different liquid phases — one with high density and the other with low density — that become identical at a liquid - liquid critical point in the supercooled phase (C ′, see the figure).

A team at the University of Nottingham used a simulation that matches experimental and in situ observations to characterize ice on a spectrum between rime ice that forms from water vapor and glaze ice that forms from supercooled water droplets.

In - flight ice forms at altitudes up to 7300 metres (24,000 feet), when the aircraft's surfaces hit supercooled water droplets suspended in the air.

Through a simulation performed in «supercooled» water, a research team led by chemist Feng «Seymour» Wang, confirmed a «liquid - liquid» phase transition at 207 Kelvins, or 87 degrees below zero on the Fahrenheit scale.

In one sentence: For first time, researchers measure properties of water at deeply supercooled temperatures, fleshing out their understanding of rain and clouds.

«So if you use those models to describe water at room temperature, you do not get the regular liquid but instead a supercooled glassy state that does not look like nature's most ubiquitous solvent,» said Xantheas.

Meanwhile, a new technique has allowed a separate team led by physicists at Stockholm University to map the unique way supercooled liquid water fluctuates between two states — both of them liquid, just different kinds.

More important, the study suggests that simulations of liquid water at room temperature with those models actually describe a supercooled glassy state, not the regular liquid.

But «supercooled,» water can remain liquid even at temperatures as low as minus 40 degrees Fahrenheit.

Given the lower temperatures and lower water vapour content at higher altitudes and a need for high supercooling to initiate condensation (in the absence of sufficient normal CCN), wouldn't an increased source of nuclei, in the form of GCRs, enhance high - and middle - altitude cloud formation?

In the absence of any ice nuclei, the freezing of supercooled water droplets of a few micrometres in radius, in a process called homogeneous ice nucleation, requires temperatures at or lower than − 39 °C (− 38 °F).

Clouds that consist of water droplets at temperatures below 0 ° C. are called supercooled clouds, and they are of great importance in the formation of rain.

Scientists measured properties of water at deeply supercooled temperatures — which may help theorists flesh out their understanding of water and help atmospheric scientists better understand rain and clouds.
