Sentences with phrase «of normal atmospheric pressure»

Not exact matches

A few molecules of H2O at normal atmospheric pressure are solid when below 32 degrees Fahrenheit, liquid between 32 °F and 212 °F, and gas when above 212 °F.

Coesite is a polymorph of silica that only forms under extremely high pressure — 10,000 times more on average than normal atmospheric pressure.

Their findings have been recently published in EPJ D and are particularly relevant for the development of novel applications in medicine, health care and materials processing because they involve air at normal atmospheric pressure, which would make it cheaper than applications in inert gases or nitrogen.

But recently teams have been able to observe that at pressures of 2 - to - 3.5 million times normal atmospheric pressure it transforms into an unexpected structure consisting of layered sheets, rather than a close - packed metal as had been predicted many years ago.

To quantify the energy change, siderite's spin transition was examined using highly sensitive spectroscopic techniques at pressures ranging from zero to about 711,000 times normal atmospheric pressure (72 gigapascals), and also revealed by a visible color change after the transition, indicating rearrangement of electrons.

CO2 at room temperature and normal atmospheric pressure has a density of 1.98 g / lt.

The team was able to pinpoint that spin transition was occurring in iron carbonates under about 434,000 times normal atmospheric pressure (44 gigapascals), typical of the lower mantle.

Unlike Earth or Mars, Pluto has no satellites or ground stations, so the types of data that are used by normal weather and climate people (air pressure, temperature, atmospheric composition, etc.) are not available for Pluto.

In August 2005, the scientists reported that they created this compound by compressing buckyballs — soccer ball - shaped molecules each made of 60 carbon atoms — at 2,200 degrees C and 200 times normal atmospheric pressure, a process that could lend itself to mass production.

So now we have surface temps of 160 F [71 C] and air temperature normal cooler by +20 C. Without an increase in atmospheric pressure, and with higher surface temperature one would see a larger difference in surface temperature between the surface and air temperature.

This pulse comes in the form of a pressure pulse within the normal seasonal atmospheric transport.

If the liquid is allowed to expand to atmospheric pressure, it cools and partially freezes to a snowlike solid called dry ice that sublimes (passes directly into vapour without melting) at − 78.5 °C (− 109.3 °F) at the pressure of the normal atmosphere.

«Relatively cool waters in the eastern Pacific often result in stubborn summer high - pressure systems over the eastern states that block storms, reducing the frequency of precipitation below normal,» noted study co-author Richard Healy of the Woods Hole Oceanographic Institution, Woods Hole, Mass. «Less frequent storms result in higher surface and atmospheric temperatures that then feedback on the atmospheric circulation to further reduce storm frequency and raise surface temperatures even more.»
