«Because we pre-compressed the water, there is less shock - heating than if we shock - compressed ambient liquid water, allowing us to access much colder states at high pressure than in previous shock compression studies, so that we could reach the predicted stability domain of superionic ice,» Millot said.

ARBUS — a nuclear reactor cooled by organic liquids of good moderating properties and high temperature of boiling at atmospheric pressure.

Vapor blankets could not develop at the high supercritical pressures under the earth's surface, because SCW is always a mixture of microscopic liquid droplets floating in a very dense vapor.

Because water molecules are an essential component of all foods, so the higher boiling point of water inside a pressure cooker means the heat transfer through the food occurs more rapidly (the liquid water is hotter before it reaches a gaseous state at boiling point) thereby reducing cooking time.

But, how does using a pressure cooker affect nutrients since the water is artificially kept in liquid state at a higher temperature during cooking?

A note on the production of skim milk powder: liquid milk is forced through a tiny hole at high pressure, and then blown out into the air.

To get the Subcool number its the same concept but on the liquid line coming off the condenser, near the high side service port.Read the High side temp shown on the high side pressure guage... (ie 130 * @ 200PSI) and subtract the actual measured line temp at the high service port from the temp shown on the pressure gauge (should be lower than the pressure gauge tehigh side service port.Read the High side temp shown on the high side pressure guage...

CO2 at high pressure forms a liquid, then ultimately reacts with igneous rocks to form CaCO3.

The vapor pressure in equilibrium with supercooled droplets (liquid H2O) is higher than that in equilibrium with solid H2O at the same temperature, so liquid droplets will evaporate to feed deposition on an effective ice nucleus.

In a pressure - cooker, the water vapor stays inside, and thus allows liquid water to get arbitrarily hot without boiling — until the whole thing explodes, which is why there is that little thinghy on top which in fact limits the pressure and instead allows the water to boil at a higher temperature than normal.

(In the global time average, diffusion of latent heat is in the same direction as sensible heat transport, but latent heat will tend to flow from higher to lower concentrations of water vapor (or equilibrium vapor pressure at the liquid / solid water surface), and regionally / locally, conditions can arise where the latent heat and sensible heat fluxes are oppositely directed.)
