Sentences with phrase «sublimation of water ice»

Water vapor can transport a lot of heat, so when Ceres formed 4.6 billion years ago, sublimation of water ice might have dissipated much of its heat into space, Campins and Comfort wrote.

Of particular interest is a bright pit on the floor of crater Occator that exhibits probable sublimation of water ice, producing haze clouds inside the crater that appear and disappear with a diurnal rhythm.

«We detected strong indications of the sublimation of water ice due to the increased solar heating — similar to how the tail of a comet is created,» explains Jessica Agarwal (Max Planck Institute for Solar System Research, Germany), the team leader and main author of the research paper.

Not exact matches

The water is likely erupting from icy volcanoes or sublimation of ice into clouds of vapor.

«The product is first frozen, then the sublimation process converts the ice into water vapor, removing most of the moisture from the product while keeping the nutritional value virtually the same,» Milchman says, adding that this is a fairly recent innovation in food preservation, one that offers several benefits over other methods, such as using artificial preservatives or dehydration, which can affect the appearance and composition of products.

The physical processes by which energy might be added into the glacier material include: (A) convection between the glacier surfaces and local surrounding atmosphere and water, (B) direct radiation onto the exposed surfaces of the material, (C) addition of material that is at a temperature higher than the melting temperature onto the top of the glacier (rain, say), (D) Sublimation of the ice directly into the atmosphere, and (E) conduction into the material from the contact areas between the glacier and surrounding solid material.

Losses from surface melting, water runoff, the breakup of glaciers into the ocean (calving), and the transformation of solid ice into water vapor (sublimation) exceed any gains through snowfall.2, 3,4,5 The Greenland ice sheet loses most of its mass on the perimeter, through a dozen fast - moving glaciers, including Helheim.5, 6

There is nothing in the phase transition from solid ice, or liquid water, to H2O vapor by sublimation or evaporation; that suddenly turns off the ability of those molecules to emit a BB like thermal continuum radiation spectrum according to Planck formula and other applicable laws (don't forget the emissivity).
