how fast dose ice melt snow?

umm...ice will never melt snow. As in ever.

Yes.  Adding salt to frozen water lowers the melting point.  \n\nConsider that snow and ice are really the same thing, in different mass quantities - water in solid state due to ambient temperature.\n\nBest to you.

An icecube doesn't melt at room temperature, it will stay at 0 degreescelsius (33 degrees Fahrenheit) untill the ice is completely melted.Only when the ice is completely melted will the temperature of thesystem rise. This is because of all the energy put into the ice isconsumed in converting the ice from solid water to liquid water. Thelatent heat of fusion/melting of water is 80 Joules per gram (it takes\n80 joules to melt or freeze one gram of water).\n\nAn ice cube melts at room temperature because it tries to\ncome intothermal equilibrium with it's enviroment. Heat flows into the ice,which increases the total energy of the ice. The molecules in thesolid water start to vibrate faster and they get enough energy tobreak free of the electromagnetic attraction that holds the solid\nwater molecules together.\n\nAfter these electromagnetic bonds break, the water becomes fluid.\n\nIf you heat water to it's boiling point the same process occurs. Themolecules vibrate enough and get so much energy that they can overcomethe force of atmospheric pressure and the water molecules escape into the atmosphere.\n\nTo that end... i dont think there is an actual melting point of ice.  There are many variables to account for when you consider the melting point of ice. \n\nRoom temperature is taken to be roughly 21–23 degrees Celsius (69-73 degrees Fahrenheit).\n\nBoiling Point, 100 C

Dry ice is frozen carbon dioxide (CO2).  As it warms it sublimates (changes from a solid state to a gaseous state without passing through a liquid state).  I believe it expands about 800 fold.  How quickly it would explode a given container depends on how much is in there plus the temperature.

The water content of snow is more variable than most people realize. While many snows that fall at temperatures close to 32oF and snows accompanied by strong winds do contain approximately one inch of water per ten inches of snowfall, the ratio is not generally accurate. Ten inches of fresh snow can contain as little as 0.10 inches of water up to 4 inches depending on crystal structure, wind speed, temperature, and other factors. The majority of U.S. snows fall with a water-to-snow ratio of between 0.04 and 0.10.

A rule of thumb is that it varies from 1.2 inches of water to one foot of snow to 0.48 inches to make one foot of snow (a ratio of between 0.10 - 0.04). It obviously depends on the compaction of the snow and the crystal structure. \n\nBy my calculations the commercial snowmaking machines use about 5 inches of water to one foot of snow, so it is obviously much denser than natural snow.

a plastic cover on a bowl of ice will keep the ice frozen for a longer time since it does not transfer heat as quickly as foil.  You can prove this using two small bowls of ice.  Measure the surface temperature of each every minute for ten minutes and record the results.

It depends on what you mean by "does it get warm?". See below.\n\nIt can snow even at incredibly cold temperatures as long as there is some source of moisture and some way to lift or cool the air. It is true, however, that most heavy snowfalls occur with relatively warm air temperatures near the ground - typically 15 F or warmer since air can hold more water vapor at warmer temperatures.\n \nWhen is it too warm to snow?  How does snow form if the ground temperature is above freezing?  Snow forms when the atmospheric temperature is at or below freezing (0 C or 32 F) and there is a minimum amount of moisture in the air. If the ground temperature is at or below freezing, of course the snow will reach the ground.\n\nHowever, the snow can still reach the ground when the ground temperature is above freezing if the conditions are just right. In this case, snowflakes will begin to melt as they reach this warmer temperature layer; the melting creates evaporative cooling which cools the air immediately around the snow flake.This cooling retards melting. As a general rule, though, snow will not form if the ground temperature is 5 C (41 F).

warm water dissolves ice faster than warm air because it can transfer and absorb heat faster than warm air of the same temperature

Salt doesn't melt ice, it reduces the temperature needed to melt it. In Antarctica the temperature is so low, that even all salt water around doesn't help melting it.

Couple good answers there. The ones about lowering the freezing point are good, but not quite there. If it just lowered the freezing point (which is true) it would never melt the ice/snow, since it nothing has affected the temperature yet. What happens is that the first interaction of salt and ice/snow (water) causes heat to be released, it is an exothermic reaction. That little bit of heat allows more ice to melt, reacting with more salt, creating more heat, melting more ice, etc. So it is the exothermic reaction that causes the melting, the lower freezing point keeps it from refreezing.

Thats a difficult question. It all depends on air pressure, wind, temperature, humidity, distance of the clouds above the earth. Velocity of the snowflake. Mass of the snowflake. It's really dependent on the situation and the composition of each individual snowflake. No two conditions are the same.

It depends on the structure of the structure of the snow particles, whether the snow is wet or dry (that is on air and ground temperature). It can be 4:1 or 8:1, and anything in between. Again, these are approximate values.

That depends on several factors - how far above ground it begins, how wet it becomes, and its shape. The latter is important because "snowflakes" are most commonly an aggergation of several of them - the more flakelike ones tending to fall slower than the more shperical ones with a denser core.\n\nThe typical dry snowflake falls at about 3-4 feet per second, which means from a cloud base of 2500 feet it would take about 12 minutes - could be 20 minutes or more from some clouds. This is one reason snow flurries or sometimes even light showers can occur from a clear sky or one virtually so (if the horizon is obstructed to some extent). The snowflakes can travel horizontally 10 miles or more before reaching the ground. Another reason is that for snow I've seen clouds disappear as they deposit their remaining flakes.

the first thing you do is figure out how much heat it will take to melt the ice, this is done by multiplying the quantity of ice by the heat of fusion\n\n10g x 335 J/g = 3350J\n\nnow figure out how much the water cools off to give the ice that 3350J that it needs to melt, this is done by multiplying the amount of water by the specific heat and then dividing this into the energy transferred\n\n100g x 4.18J/gC = 418 J/C\n\n3350J / 418 J/C = 8 degrees C\n80-8=72C\n\nso now you have 100g water at 72C and 10g water at 0C, so you can figure out what this mixture will equilibrate to\n\n100 x 72 =7200\n10 x 0 = 0\n7200 / 110 = 65.4C will be the final temp of the mixture\n\nso the answer is D

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