CAnswer: C- The particles in nitrogen gas, which is in gaseous state, are far apart from each other and are able to move freely and randomly, hence it does not have fixed shape. Ice is a solid and the particles in it are regularly packed in an orderly manner, with the particles vi...
The other theory is that ice is just slippery, because the outermost layer never turns to a solid. According to this theory, the water molecules at the surface of the ice move more, because they're at the edge and there aren't any molecules above them to help keep them in place. ...
Dry ice will go directly from a solid to a gas at room temperature. Going directly from a solid to a gas is called ___. (a) deposition (b) condensation (c) sublimation (d) solidification. What is it called when a solid becomes a gas? a. condensation b. ...
The water under particular temperature solidifies and forms ice. The slippery nature of ice makes it perfect for skiing. The reason that ice is slippery is something no one can pinpoint. It is a grey area much the same way we have not gotten to the bottom of what makes a bicycle stabl...
Why is Antarctica an extreme environment? Why is the melting of ice not a chemical reaction? Why do polar bears depend on sea ice? Why are there larger waves in the Antarctic Ocean? Why is Arctic Sea ice important? Why is ice the solid form of water?
You can't see the water vapor, because it's a gas, but it is still there.由于水蒸气是气态的，所以我们看不到它，但它依然真实存在。Water can be either solid as ice, liquid as water, or gas, which is a vapor.水能以固态存在，比如冰；能以液态存在，比如水；或以气态存在，那就是水蒸气...
Why is ice less dense than water? Ice is less dense than water because of the arrangement of the water molecules. As a liquid, water molecules pack together in a random arrangement. But as a solid, ice form as crystal, with each molecule arranged in a grid-like pattern. This crystal ac...
Ice: An Elusive Research Subject Water is a tricky chemical compound. As opposed to most liquids, water becomes less dense as it freezes and is therefore lighter as a solid than a liquid (as is illustrated by ice cubes floating in a glass of water). ...
Presumably, theliquid makes the surface slippery because liquids are mo-bile, whereas solid surfaces are relatively rigid. Askingwhy ice is slippery is thus roughly equivalent to askinghow a liquid or liquid-like layer can occur on the ice sur-face in the first place.Pressure meltingThe common...
buffer against sea level rise—making it integral to preserving Arctic glaciers in a warming climate. Firn is porous and spongy, which allows water to pass through on its way to the solid ice layer below, where it can refreeze, adding to the existing ice sheet instead of flowing to the ...
