What is the best method, other than heat, to melt ice?

Salt or calcium chloride sprinkled on ice will turn the water in ice to a liquid with a much lower freezing point, thus dissolving the ice.

The steam.  It would have to go through a phase change and give up a bunch of energy to turn back into water at 100.  Assuming you mean equal mass of water and steam. \n\nSame question for ice.  How much energy does it take to melt 1 Kg of ice at 0 to water at 0?

Ice it 20 minutes, let it warm up for 20 minutes. Do this once an hour for about 4 hours. Keep it elevated as well.

The latent heat of fusion -- once you cool water to 0°C, you have to remove more heat to actually crystallize it.\n\nIce at 0°C requires the addition of heat to melt into water at 0°C.  That heat comes from whatever you are cooling.\n\nThe latent heat of fusion for ice is 333.6 joules/gram

There is no set speed because ice melts from the outside first. A solid block of ice, 1000g, will melt more slowly than 1000g of ice cubes, which will melt slower than 1000g of crushed ice. The more surface area exposed, the faster it melts. Also, it depends on the temperature of the ice. Ice from a -5C freezer will melt faster then ice from a -30C freezer.\n\nYou have asked this question twice. Why don't you carry out an experiment and find it our for yourself, using a kitchen scale, a timer, and a thermometer?

Forming ice crystals?\n\nThe easiest way is to place a petri dish in the freezer and once cold, place a single drop of the water solution on it.  The ice will form immediately.  You can store it in the freezer until you need it.  A microscope slide can be used this way to get great specimens to look at under a microscope too.\n\nFor non-ice crystals, the two simplest compounds to use are table salt (Sodium chloride) and cane sugar (Sucrose).  To make crystals with these, dissolve as much salt or sugar in a container of boiling water until no more will dissolve.  Upon cooling, crystals will start to form.\n\nSome people will use a weight on a string to hang in the solution to allow the crystals to form rapidly.  If you just add a few solid crystals once the solution is cold, you can get good crystals without the string inside.\n\nLess common substances which can be used to made other crystals at home would include Copper sulfate (called blue stone, it is used to treat algae in fish tanks and ponds) and Magnesium Sulfate (Epsom's salt)

Just make sure that the ice does not melt, if not you are going to rot real fast.

well, it depends on what you mean by "liquefied".  most certainly it can be ground or sanded into a fine dust (sawdust) and then mixed with water - voila, liquified wood.\n\non the other hand, if you mean melted, the way you melt ice or iron.. not really, no.  wood is a pretty complex substance, with lots of different kinds of chemicals arranged into cells.  chemically speaking, it's mostly carbon and water, and trace amounts of a bazillion other chemicals.  if you heat it up, some other chemical reactions will happen first (combustion, for instance, in the presence of oxygen).  \n\nin the absence of oxygen, you make charcoal if you heat wood to around 300C - the water evaporates away, the bonds break and all the other chemicals are driven out.  what's left is a chunk of solid, mostly (90%) carbon in noncrystalline or "amorphous" form. \n\nif you KEEP heating it, always without any oxygen because it'll burn otherwise - eventually this stuff will melt, but solid carbon melts at around 3800C, which is getting pretty close to the temperature of the surface of the sun.  so it's pretty difficult to do, though if you increase the pressure, the melting temperature will go down - this is how they make synthetic diamonds.\n\notherwise, wood can be "liquefied" through other chemical processes, such as decomposition/rotting - this is where oil comes from - but by the time it's liquid, it hardly qualifies as wood anymore.\n\nso, i guess the short answer to the question is no, it can't be.

All matters dosnet expand on heat. Take ice, it shrinks or melts on heat. Hope you liked my short and sweet answwer.

A rough example as follows:\n\nQuestion: What happens to ICE when you PLACE IT IN WARM WATER?\n\nHypothesis: IT TURNS INTO LIQUID.\n\nMaterials: ICE, CONTAINER, WARM WATER.\n\nSteps: 1.  FILL CONTAINER HALF WAY WITH WARM WATER.\n       2.  PLACE ICE IN CONTAINER.\n\nObservations:  I OBSERVED THE ICE MELT.  THE ICE TRANSFORMED FROM A SOLID TO A LIQUID.\n\nConclusion: ICE A SOLID CAN TRANSFORM INTO WATER A LIQUID WITH THE ASSISTANCE OF INCREASED TEMPERATURE.

You can use dry ice, which is solid frozen carbon dioxide, around the ice cube to keep it cool sot hat it will not melt.\nBecause of its particular characteristics, dry ice requires special precautions when handling. It is extremely cold and there should be no direct contact with skin.\nIt is constantly sublimating to carbon dioxide gas, so it cannot be stored in a sealed container as the pressure buildup will quickly cause the container to explode.\nWith these precautions, using dry ice is the most effective way of ensuring that the ice cube won't melt.

It's a solid, so it's already frozen. Heat it up enough, and it will melt.

Use dry ice. It is always -78 or colder.

Melt the whole mixture and do an electrolysis. Would be quite expensive a process, but might be the only possibility e. g. on the moon in order to produce oxigen. Melting heat might come from sun and electricity from solar panels.\n\nI understood in principle such a reaction is done to make aluminium from bauxite. But in this case the producers immediately use up the oxigen through burning carbon electrodes in order to win the melting heat.

It doesn't.  Ice melts more slowly on a colder surface because when ice melts it must draw heat from the surrounding environment, and when there is less heat available it takes longer.\n\n____________\nEdit: as a college science major, I can tell you it simply doesn't work that way.  However, there are a number of factors besides temperature that effect ice melting.  For example, if the piece of ice on the colder block was considerably thinner than the ice on the warmer block the one on the colder block might still melt faster.  In biology, we sometimes melt small amounts of liquid on ice because bad things happen if they get too warm, and two microliters of frozen liquid on ice generally melts faster than ten mililiters in warm (about 98˚F) water.\n\nAnother factor that effects melting point is solutes dissolved in the water before it was frozen.  Salt water freezes at a lower temperature, and consequently melts at a lower temperature, than pure water (that's why the salt the roads in the winter).  If there were a lot of salt dissolved in the piece of ice on the cold block, then depending on the temperatures of the two blocks, the one on the cold block might melt faster.\n\nIt's also possible that one or both pieces of ice weren't water at all.  There are plenty of clear liquids out there that melt at various temperatures.  A compound with a lower freezing point will tend to melt faster, possibly even at a lower temperature.\n\nAnother factor is the starting temperature of the ice.  In one of the biology labs at my school we have a freezer that's at -80˚C, and the normal ones at 4˚C.  If you take a piece of ice out of the -80˚C freezer and one out of the 4˚C freezer, they're both frozen, so they're both ice, but the one at -80 is a lot colder, and is going to take a lot longer to melt, even at a warmer temperature, because it has to warm back up to 0˚C before it can even start to melt.\n\nBut, of course, the obvious explanation is that either your teacher lied to you, or you lost track of which block was which at some point in the demo.

Put water under a vacuum. It will boil at room temperature. \n\nOr do you just want to create the illusion of steam? You could put dry ice in water. Then it will be could and appear to be steaming and boiling. And many people will think it is steaming.

Could Ice be used to produce fire?\n\nSure, fashion the Ice into a lens and use the lens like a magnifying glass to ignite a fire.  If that's what your asking.
