if it is pure water, then it is 0C or 32F

The melting point and freezing point of a substance can be different. For water, the melting point is 0c. This is also the freezing point, provided there are nucleators, little bits of impurity, in the water. But if the water is perfectly pure, and if the volume is small, you can supercool it to -40c, and it can still remain liquid. Think of it this way: freezing proceeds as liquid water molecules come in contact with an ice crystal and become trapped. But can you have just one ice molecule in a sea of liquid water? A single ice molecule would be indistiguishable. So until a crystal spontaneously appears, the water will remain liquid.

Well 0 celcius or 32 farenheit is the freezing point of water. the water has to reach that temp to freeze. sometimes water will freeze on surfaces with the air temp a little higher. if the surfaces are colder than the air.

The Celcius scale is based on water :
<= 0C water is solid (frozen)
between 1 and 100C water is liquid
>100C water become a gas
on standard pressur, steady air, etc...

I heard that it is approximately 4degrees Celcius.
