Such geometries can persist at very high pressures, even if the underlying structure undergoes phase changes both subtle and dramatic with varying pressure.

The liquid condensed at the bottom evaporates creating local cooling and rises; the way ocean water and all water does from the surface as an enormous pool of evaporative phase change refrigerant for the surface (and the atmospheric bath of nitrogen / oxygen).

This is due to so - called phase change materials, novel materials that change their optical properties depending on the arrangement of the atoms: Within shortest periods of time, they can change between crystalline (regular) and amorphous (irregular) states.

The overall balance of the game is pretty good as well, with tools like grabs, counters, and phase changes allowing for some pretty clever comebacks.

«We have known for a long time that aerosols impact both the heating and phase changes [such as condensing and freezing] of clouds, and that they can either inhibit or intensify clouds and precipitation,» Russell Dickerson, an atmospheric scientist at the University of Maryland, tells The Epoch Times.

At Tmax, for example, there has been a steady T rise as the sun moves higher in the sky, the rise helped by convection of air with hot packets in it surrounding the site, held back if frost has formed overnight, complicated if there is snow around and water phase change effects need consideration, hindered or lagged by the thermal inertia of the screen surrounding the thermometer as the screen heats up.

No — we wouldn't expect just whatever some endlessly busted bunch of pseudo scientific quacks say, to define the thermodynamics of a warm rock, being scrubbed by frigid winds, immersed in freezing cold phase change refrigerant.

Importantly: That same phase change occurs over land in temperate climates, especially the wide flat expanses of the center of North America.

the lapse rate is solely controlled by thermodynamics e.g. convection & phase change without influence by radiative forcing

Any heat radiation penetrating the canopy and incident on the soil again goes towards phase changing water, water in the soil moisture, but this happens in a limited quantity based on saturation point of vapor in the surrounding.

This solid to gas phase change is known as sublimation and removes nearly all the moisture from the product, while retaining most of the nutrients.

However if we move to more average Earth condition with average levels of humidity introducing condensation phase change then the radiative contribution from H2O will increase dramatically.
