What rock does recrystalization of unmelted material under high temperature and pressure result in?
Recrystallization of unmelted material under high temperature and pressure can result in the formation of metamorphic rocks such as marble from limestone or quartzite from sandstone.
What is the nutritional value of cheddar cheese when melted and unmelted?
See http://www.answers.com/topic/cheddar-cheese-1 Melted/unmelted isn't going to make much difference.
Fragments of unmelted rocks that are sometimes incorporated in magma are known as?
xenoliths
Do all solids dissolve in liquid why?
No, not all solids dissolve in liquids. Whether a solid dissolves in a liquid depends on factors such as the nature of the solid and the liquid, the solubility of the solid in the liquid, and the temperature and pressure conditions. Solids that are insoluble do not dissolve in liquids because their intermolecular forces are too strong to be overcome by the solvent.
What is the nutritive value of cheese?
Exactly the same as its unmelted counterpart.
Why is the mantle a solid but magma a liquid?
=== === The presence of water in hydrous minerals which are being subducted can speed melting of some minerals. Others crystals that would be solid at a deeper depth can melt in a high-temperature, subducting environment. The resulting partial melt can carry unmelted material upward, where lower pressure allows more melt to occur. This process can occur all the way up to volcanic eruption, or the rising magma can partially or entirely stop and cool in place.
Does melted ice cream weight the same as unmelted ice cream?
Yes. Just like a pound of fresh hamburger meat is still a pound of hamburger meat after it's frozen.
What mass of ice remains unmelted after equilibrium is established Contents of the insulated container water liquid 100g at 20C water ice 1650g at 0C water steam 175 g at 100C?
To solve this problem, calculate the energy required to bring all of the ice to a liquid phase. Then calculate the sum of the energy required to bring the water to 0 degrees C and the steam to a 0 degree C liquid phase. Find the difference between the energy required of the two processes. If melting the ice requires more, the difference in energy can be used to find the mass of ice remaining in the relationship of m = q/latent heat of fusion of ice.
What local materials will keep ice from melting fast?
Anything that dissolves in water. Usually salt is used. <><><> Salt makes ice melt faster- question was keep from melting. Materials that insulate ice from air or water around it. Leaves, pine needles, and sawdust will allow ice to stay cold and unmelted.
When snow melts what happens to temp?
Melting is a phase change. Typically what happens is that the snow absorbs heat until it has warmed to the melting point. As it continues to absorb heat, it undergoes an isothermal (the temperature doesn't change) phase change (melts). Once it has melted, it may continue to warm up above the melting point temperature. In practice different parts of the snow will be at different temperatures. The snow at the surface will be absorbing the heat and melting. As it melts, the water from the melted snow runs down into the unmelted snow where it supplies heat to that snow to start warming it up.
How does magma rise?
Magma is more buoyant than lithospheric rock, and as such it will push toward the surface. On the continents, magma in intrusions can follow weaknesses in the crustal rock to reach the surface, or in some cases, simply melt its way through from the heat delivered by the intrusion. At divergent plate boundaries, where the lithospheric plates are pulling apart, hot rock from the mantle rises and melts from decompression melting, filling the space left from the parting plates. At so-called hotspots, such as the Hawaiian volcanic mountain chain, magma plumes are thought to rise up from the mantle-core boundary and burn through the moving lithospheric plates, creating first submarine volcanoes, then islands.
Is a migmatite foliated or non foliated metamorphic rock?
Difficult to give you a precise answer, migmatites are composed of a leucosome which is new material crystallized from incipient melting and a mesosome which is old material that resisted melting. These two materials may form a fine fabric which imparts a foliation to the rock. The leucosome may also be incoherently folded. Also if the migmatite is forming from a foliated source, the foliation may persist. Thus migmatites are metamorphic rocks that show characteristics of incipient melting and they may or may not show a foliation too, the foliation is not a critical characteristic of a rock being a migmatite.
