How does water in freeze?

Question

i am doing a science project and i can only find about hot water freezing..does anyone know any good books or websites on this topic?

* how does water freeze?

Answer 1

hot water freezes the same way cold water freezes. As the external temperature drops, the water attempts to maintain an equilibrium. Its heat (energy) leaves to warm the air surrounding it. Now, with sufficient heat, the atoms inside water are moving around in random patterns. The hotter the water, the faster the molecules are moving (which then leads to gas in which the molecules are completely free of each other). Thus, the colder the water, the slower the molecules are moving around. At 0 degrees Celsius (32 degrees Farenheit) the molecules cease their movement and form crystalline structures.

But any website you find about hot water freezing should work for a more detailed description.

Answer 2

Hot water freezing ?? No scientist can alter the state of science, that is hot water will turn cold first, before freezing at 0 degree Celsius.

Answer 3

warm water would not freeze.yet while 2 water samples at 0c one clean from a faucet the different boiled then cooled to 0 c then the pattern that have been been boiled might have much less dissolved gasoline than the unboiled pattern. 2 circumstances might then prepare.better cooling might reason gasoline bubbles to kind interior the unboiled liquid and those may well be probable to decelerate the flow of warmth out of the containing vessel so subsequently slower warmth extraction and the boiled pattern might freeze first.yet yet another factor then comes into play that's that ice desires surfaces to nucleate on and those would desire to be liquid/sturdy or liquid/gasoline and extra notably triple junctions;the place sturdy,liquid and gasoline stages meet,and so the unboiled pattern might freeze first.So the situation will no longer be able to be analysed:it is going to selection with pattern purity and the circumstances at liquid/sturdy interfaces.that's attainable that a liquid may well be cooled 50c under that is authentic freezing temperature if there are no nucleating sites.

Answer 4

if you can only find websites on 'hot' water freezing, then wouldnt it need to get to 'room' temperature before it freezes? 'Hot' water freezes the same way room temperature water will freeze, so those websites that you've found are ideal.

Answer 5

don't understand exactly what you are asking, but I do know that people always say that hot water in ice cube trays freezes faster than cold (don't know if that is the case) but I do know that when I lived in the country, my water pipes froze up a few times, and the hot water always froze before the cold pipes did
