- Water needs to be less than 0 degrees celcius for it to freeze, so I guess the changes regarding temperature is that instead of being above 0 degrees celcius, it is less than 0 degress celcius
- In terms of density, ice is less dense than water, as the particles expand. If you think about it, ice floats on water is it is less dense. If it was more dense it would sink!

What energy changes occur when water freezes?
When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as: reactants --> products + energy
How does the volume of a kilogram of water when change when it freezes?
it changes because when it freezes, the molecules within the water slows down thus changing the placement of it, which also changes the over size or volume of water.
Does density change when the size of an object changes?
No. A drop of water and a tankerful of it have the same density. But these are two different masses of the same material. If you have, say a piece of metal and heat it up so that it expands, and there is still the same amount of substance, then the density decreases as the substance expands. Water expands as it freezes; that is why ice floats in water.
Does the density of water depend on the temperature of water?
Most definitely yes. Water has its maximum density at 4° C. By definition this is the point at which clean water has a density of 1 exactly. It gradually becomes less dense as its temperature rises. When it changes state for liquid to gas, it undergoes a tremendous change in density, dropping to 0.0006 at 100° C. When it freezes, it also undergoes a big change in density, but not as drastic. It drops to 0.9150 at 0° C. Since it is less dense than liquid water, ice floats.
Is 32 degrees Fahrenheit the temperature at which water freezes?
Yes, at this temperature the structure the atoms of water are orgainzed in changes, and the state of the substance changes.
Why when the water freezes the density goes down?
Its density goes down because when water freezes it expands.
When water freezes what causes it to float?
The density of ice is lower than the density of water.
What energy changes occur when water freezes?

What does water do when it freezes that is unusual?
It expands, which reduces its density.
When liquid water freezes into ice its density .?
Decreases
Does water volume decrease as it increases in temperature excluding evaporation or boiling in an opposing manner to the increase at freezing?
No it increases in volume as it freezes. This desreases the density of ice to that of water, that is why ice floats on water. and This freezing of water as it freezes can crack open pavement or frost heaving.
What freezes first water or milk?
water, the density is less Milk normally freezes between -0.53 and -0.56 °C. Water freezes at 0.

How water changes into snow?
it freezes. from the coldness up in the sky
What properties change when water freezes to ice?
Its volume increases and its density decreases.
Is it true ice floats on water because water expands when it freezes?
It is true that water expands as it freezes, but the reason it floats on water is because the density of solid water (ice) is less than that of liquid water. And the density of ice is lower because of the expansion (same mass/larger volume).
