What happens when water change to ice?
In ice, each molecule of water is hydrogen bonded to four other water molecules, forming a hexagonal crystal lattice. This structure causes the ice to increase in volume and become less dense when it freezes.
The freezing point of H20 is 32 degrees F, 0 degrees C Answer: Water and ice change state (melt or freeze) at 0oC The temperature of the water and ice will stay at that point until the the change of state is complete. The ice turns to water if there is heat coming in (its environment is above 0oC). Water turns to ice if heat is leaving the system (its environment is below 0oC)
If you have ice in water the temperature of the water will not increases till all the ice has melted. The reasoning why this happens is to do with temperature equilibrium and is slightly complicated. Put simply it is that it cant increases the temperature as the ice will draw in the heat before it effects the water as the ice is colder.
