what is colder ice or ice water?

Depends on the quantity of ice in the water, time you measure it at, etc. All depends on the precise details of the experiment.

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

If you put hot water in the freezer it turns to ice faster.\n\nA famous scientist named Kelvin figured that out because hot water molecules move faster so the cold in the rfreezer makes them slow down faster than cold water molecules which are already moving slow, so hence the hot water freezes faster the hot water is "shocked" by the cold as it were.

Ice water? If you have ice and water together they keep each other at the same temp. 0 degrees C. If you add salt this will make the ice melt at a lower temp. which will cause the water to be lower temp. also, giving you a below 0 C reading.

snow is a form of precipitation and ice is frozen precipitation.

Thermal intertia.  It works the other way too, cold water boils quicker than hot water.  The reason is when hot water is placed into the ice cube tray it immediately begins cooling.  Then when you put it into the freezer it continues to accelerate more and more quickly to the low temp desired.  Cold water would begin warming as soon as it gets put into the tray and then you have to cool it back down (opposite direction heating takes more energy)

Could be that different chemical compounds freeze at different temperatures.  Water freezes at a lower temperature than 36 degrees but not everything does.  That is also like why you put salt on ice to thaw it, it lowers the freezing point, so it has to be a lot colder before you get ice.

dry ice is actually solid carbon di-oxide. solid hydrogen is called hydrate, and if you could make is solid at atmospheric pressure it would be very cold.

Ice crystalization begins at 32f.  At 33 it's just water.

Cold. Their water evaporates slower.

ice is water frozen. you can see through water, so you can see through ice. snow, however, is made of ice crystals that lump together. all of the lumps put together gives off that white color, and makes snow.

it doesnt, however the energy is lost faster in hot water than in cooler water.  The rate at which all water freezes is the same.

ice has lower density, so it will either have larger volume or lower mass/weight than water.

Ice takes up more volume than water, so the pressure is higher when you have the water in the freezer.  Crystals form at lower energies where entropy is lower, and higher pressure is equivalent to higher energy, so water remains a liquid.\n\nWhen you open it the pressure is released.  Gas expanding cools the air (entropy again) thus making the surface of the water lower in energy and promoting crystalization.  Poke a hole in the bottle and try this and the crystals will form in the freezer before you open it.

Absolute zero.  There are ways to keep water from freezing using pressure, motion, impurities, and so forth.

Fist of all let me correct that, the word Ice has no singular; on the contrary you might as well lower the external temps or purify the ice.

Ice floats on water because it is less dense than water, meaning it has fewer molecules per volume. This is because of the Hydrogen bonds. In fact, while other substances contract when solidified, water expands. That's why it's less dense, and not because it has air inside. Furthermore, when the temperature decreases and reaches 4 degrees Celsius, every water molecule is Hydrogen-bonded to 4 other molecules near it. Then, they form into a crystal lattice structure, and it holds them further apart.
