When you touch some ice, a lot of heat from your skin is first needed to melt the ice. This so-called phase-transition requires a relatively large amount of heat. Once molten, the resulting liquid water will still be 0 deg C, so at that point you have already lost a lot of heat and still have to heat up the 0 deg C water, hence ice appears colder.
Water, whether liquid or solid, can be 32 degrees, F in either state. There is 32 degree water, and there is 32 degree ice.
The difference is that in ice form at 32 degrees, water has lost a lot of energy as compared with liquid water at 32 degrees.
Celsius is a measurement of energy. It measures the amount of particle activity in a substance. Therefore snow at 0 degrees Celsius has a equal amount of energy that water has at 0 degrees Celsius (Although, water freezes at 0 degrees Celsius so I do not believe you could have water at 0 degrees Celsius).
Water, because it has 'latent heat' which is heat that must be removed before it will freeze (albeit that when it has frozen its temperature is still zero degrees).
Ice at 0˚C has more energy because it has latent heat also.
It takes a pretty large amount of energy to melt ice into water. The ice will "steal" that energy from its surroundings to melt. That makes it more effective at cooling.
Ice can be colder than zero degrees centigrade; there is no law that keeps ice at zero degrees. If there were such a law, then ice would be a perfectly clean, infinite source of energy. We could simply pump heat out of ice, and the heat would never diminish. But this is not the case. So it is possible to add water ices of different temperatures and in the long run the temperatures would balance out.
The freezing temperature of water is 0 degrees celsius or 32 degrees fahrenheit so it is colder than the freezing temperature of water.
H2O is water. Water is ice when it freezes. Water freezes at 32 degrees Fahrenheit / 0 degrees Celsius
yes
Water freezes into ice at 0 degrees Celsius. Anything above that it will melt. Therefore ice must be 0 or below
This is because the ice at 0 deg C is colder to the extent that the latent heat of freezing has been removed from the water at 0 deg C.
Water can change into ice by freezing it to low temperatures (0 degrees and below)
Ice water will quickly get warmer. Ice, a mixture of ice and water actually, will remain at 0 degrees until all the ice has melted. Ice has a certain amount of latent heat; it requires heat energy to convert ice at 0 degrees, to water at 0 degrees.
well for something to freeze it has to be 0 degrees or lower which is what ice is, frozen water. so the water has to be 1 degree or more to NOT freeze so the ice is colder than salt watercoz salt water is not frozen... does t6hat make sense? Actually, salt water CAN be colder than ice because the salt lowers the freezing point of the water.
The water itself isn't frozen, so it doesn't have to be that cold. The ice in it only makes it colder than room temperature.

Some Ice would melt, absorbing heat (enthalpy for the phase transition). Since Salt Water has a lower freezing point than zero degrees, the liquid will cool down. This colder liquid will chill the ice (if it isn't already colder than zero) and the result will be a mixture of ice and water that is colder than zero degrees C. This is why adding salt to ice buckets can cool Champagne faster.
The freezing temperature of water is 0 degrees celsius or 32 degrees fahrenheit so it is colder than the freezing temperature of water.
0° celsius is 0° celsius, whether it's water, ice, dogfood, glass, stainless steel, or vodka.
0 degrees Celsius is a colder temperature than 40 degrees Celsius. 0 degrees Celsius is the freezing level for water. Any positive number above 0 degrees Celsius is a warmer temperature.

Ice wont melt at temperatures colder than freezing. Any degree above that will make the ice melt exponentially faster. For example: At 35 degrees, ice will remain ice for a long time. At 212 degrees it will disappear rapidly. At 1000 degrees, it will disappear in a puff of water vapor.
