how does ice at 0 degrees Celsius turn to water that is zero degrees Celsius?

Question

Thanks for the great answers. It's going to be difficult to pick the best.

Answer 1

The phase change from solid to liquid requires a lot of energy. If ice is at 0 degrees but doesn't have enough energy (or heat) to make the phase change, it will stay a solid. If the energy is provided, it becomes a liquid at 0 degrees. It work in reverse the other way, too, as well as from liquid to gas and back again. Incidentally, that's why it hurts more to be burned by steam at 100 degrees than it does water.....the steam has the extra energy needed for the phase change stored in its bonds.

Answer 2

If ice and water are together in equilibrium, the temperature of both is 0ºC. It will stay that way until all the ice is melted or all the water frozen (depending on whether heat is being added or removed). Any heat input is absorbed by the energy of fusion to melt the ice. Any heat removed is absorbed by the energy of fusion to freeze the water. In any case, the temperature does not change. The temperature of 0ºC applies only to pure water.

Answer 3

Latent heat is the heat required to change the state of the mass without changing its temperature. There fore latent heat is required to change the 0 degree ice to 0 degree water and 100 degree water to 100 degree steam. all centigrade units.

Answer 4

Ice can form from +4ºC and lower depending on atmospheric pressure. A simple change in atmospheric air pressure would be therefore be enough to melt or freeze water at 0ºC.

We have to remember that all measurements are only correct at the place and conditions they were defined in. So that even ignoring changes in atmospheric pressure, the conditions to freeze or thaw water will depend on it's height above, on or below sea level.

Answer 5

The degrees are same but the difference comes in the heat called Latent heat.

Answer 6

in case your thermostat is precise adequate to somewhat make it 2 stages celsius on your freezer, sure, even with the undeniable fact that it would take a at the same time as, because your freezer is nicely-insulated. finally, even with the reality that, each and each and every of the contents of your freezer would attain an same temperature, and any of it it truly is water (at the same time with the juices contained in the turkey, to illustrate) ought to have melted.
