What happens if you submerse a)ice b) diamond in liquid Nitrogen?

nothing would happen.. you're just chilling them to 77 kelvin.

The answer is either 0% or 100%. If ice is 0 degrees C it will remain as ice. [in theory]

Dry ice (CO2) dissociates - ie makes a transition from solid to gas. Remember that state change is potential energy in the atom, and temperature change is kinetic? Sublimation is only potential.\n\nWater makes the change to liquid (potential), then heats up (kinetic), then changes to gas (potential).\n\nDo your own homework.

The polar ice will melt causing a massive increase in the amount of water on the Earth.  This flooding will then cause majority of the land to be submerse in water.  That's the main jist.

The freezing point drops, by the Clapeyron equation. See the attached reference for details. \n\nThe answer above is dealing with ideal gases, not liquid water.

Ice lowers the melting point of water, so it causes the ice to turn to liquid water and break up.  If it's *really* cold, this doesn't help.

Liquid Nitrogen IS dry Ice. Just add water and you get smoke! Whatever you do, don't put it in the toilet, it will be cute at first, but it could break the bowl. And NEVER ever NEVER put dry ice in a closed container. Just don't do it. It is not neat or cool and it is very expensive, painful and scary.

water freezes at 32 degrees Fahrenheit, and 0 degrees Celsius\n\nthe colder the faster

>>>>>at 4 degrees above its freezing point, water sinks.\n\nThis is true.\n\n>>>>any lower, and it begins to freeze, forms crystals, and floats.\n\nThis is not true. Water begins to freeze at 0oC, not at 3.9oC or even 1oC.\n\n>>>>any warmer, and the molucular action makes it less >>>>dense.\n\nThis is not true. Water becomes less dense at warmer temperatures due to kinetic motion impeding the formation of hydrogen BETWEEN molecules.

Well the obvious answer is you add some thermal energy to it and it first turns to a liquid and then a gas.  However, solids can "sublimate" directly to a gas under certain conditions, namely when the solid is not in STP (standard temperature and pressure).  For example, at higher altitudes (thus lower pressures), ice sublimates directly to a gas rather than becoming liquid water first.  This is why mountains about 9K feet are distinctly arid.

The ice gives the dissolved gas (carbon dioxide) a surface upon which to gather.  Once the bubble is formed, it is no longer in direct equilibrium with the liquid and rises.

Density of ice is less than that of water.

salt water will freeze, but at a much lower temperature than non salt water. the north polar ice pack is non salt water, and the saly wayer flows underneath it. submarines ofter pass under the pack while on patrol.

Without introducing a 3rd substance, there are only 2 methods to accomplish what you're asking.  \n\n1/  increase the density of the substance you want to submerge, but without knowing the physical properties it's impossible to propose anything\n\n2/  decrease the density of the water:\n\nput whatever you want to submerge in a pressure vessel and pour in water.  make sure that the combined volume of the water and the substance is less than one or two percent of the total volume of the vessel.  place the lid on and heat until the temperature reaches 120 to 130 degrees C.  your substance is now submerged in water.\n\nYou'll want your teacher to assist to prevent an explosion.

most solids are more dense than the same substance in liquid phase and will sink.  Water/ice is an exception to this rule.

Yes, it does.  This is evident by water freezing in enclosed containers (such as pipes) and deforming them, sometimes even rupturing them.  \n\nWhen water molecules become cold enough to freeze, or change into a solid form, their crystal structure is less dense than when in liquid form.  This is due to the inherent shape of the water molecule and how the molecules line up in solid form.\n\nIf you live in a colder climate, it's a standard procedure to drain any remaining water out of things kept outside over the winter, such as boats, swimming pools, outdoor water pipes, etc.  Otherwise you can almost expect them to be ruined by the time you want to use them again.
