u can't have water upto 40 below zero!!!
the lowest temp(in centigrade) u can reach is -12 c
this is achieved by a process called super cooling
in this the temp of the surroundings is controlled, and care is taken that the surface of the water is not disturbed
similarly u can super heat water upto 137 c

When there is a mixture of pure water and pure ice the temperature is always at 0 deg. After all the water is converted into ice then the ice's temperature can be lowered to any extent.

Ice can exist at any temperature lower than 0 deg. C
0 Deg. is the temperature at which water (under normal atmospheric pressure) turns from liquid to solid. If you lower the temperature further the water will simply remain in ice form.

Yes. 0 degrees is just the temperature at which water becomes ice. Ice itself can be much colder than that.
You can also cool water to below 0 deg without freezing it by lowering the air pressure.

Yes, 0 degree centigrade is where the state change from solid to liquid happens, but ice can be taken to lower temperatures.

Yes, 0 degrees celcius is just the temperature where water begins to freeze under normal conditions.
In fact, scientists have had water in liquid form at temperatures as low as minus 40 degrees below zero in laboratory conditions. That means that below -40C it became a solid (ice).

yeah and a really simple way to do it is to add salt to the ice thereby reducing the freezing point of ice below 0 degrees centigrade.

it is by using that's called collegative (sp) properties. Bascilly the melting component of a liquid is decrease by a collection C by each and each time a mole of substance is dissolved in it. As salt is highy dissoluable in water it is going to diminish the organic freezing component of water by x ranges and for this reason 0 C isn't the backside temperature for it.

yes you can, 0 degrees centigrade is just the beggining of freezing point thats under normal condidions.

just apply more pressure to the pure water, or you can expand its volume
