Water freezes into a solid phase when it turns into snow.
physical change, because the frozen rain can be turned back into rain (or water if you want to be exact) But a good example of a chemical reaction would be, you have the ingredients for a cake, you take those ingredients, mix and bake them, that would be a chemical reaction because it cannot be turned back into a cake
No. That is not possible because water, which becomes clouds then rain/snow, is not going to take up with them the purple colored molecules of some sort to make the snow purple. (Unless a Volcano has recently erupted and the ash mixed with the snow, resulting in a purple, gray snow.) I've only seen it happen once.
oil doesnt freeze !2nd Answer:Oops! Oil does freeze. Take vegetable oil, for example. Corn oil freezes at -20 degrees C. Water freezes at 0 degrees C. Coconut oil freezes at +25.4 degrees.So, water freezes sooner than some vegetable oils and later than others.
Water freezes quicker because it is a one ingredient while others take longer time to freeze.
Adding nothing to the water should not affect the rate at which the water freezes. Adding substances, though, can noticeably depress the freezing point so that it will take longer to freeze than pure water under the same conditions. Salt is commonly used for this purpose. Adding nothing to water isn't expected to do anything to the rate at which it freezes.
When the temperature is below 32°F (0°C), water freezes and can take the form of ice or snow, depending on atmospheric conditions.

Its very unusual for a substance to expand when it freezes, water is just odd that way. Its just a property of water, its moleucles expand in the area they take up and take up more space.

Because when water freezes, it expands. If there is no other space to take up, it has to push the walls of the container out

0 degrees CelsiusWater begins to freeze at 32 degrees Fahrenheit, or as stated 0 degrees Celsius. Hot water will take longer to freeze than cold water since the water will take time to cool to the proper freezing temperature. The freezing point does not change, however; water will have to be cold before it finally freezes.
Typically, the solid phase of a substance is denser than its liquid phase, because higher molecular energy makes the liquid molecules take up more volume for a given mass.An important exception is solid water (ice) which takes on a lattice molecular shape and expands when it freezes, so ice is less dense and floats on liquid water.
just take a cup of water and put it into the freezer.wait for about 2hourstake it out and weigh it
The water will expand on freezing, so taking up more space.
