Question

when water at0c turns to 0c ice then​

Answer 1

Answer:

If water freezes at exactly zero degrees Celsius, and ice melts at exactly zero degrees Celsius, what would happen to a bowl of ice and water at exactly zero degrees Celsius?

Is low blood oxygen levels (SpO2) dangerous?

Equilibrium will happen. The amount of ice and the amount of water will stay exactly the same, indefinitely.

In order for ice to melt, it has to absorb heat. In order for water to freeze, it has to release heat. If the mixture is neither absorbing nor releasing heat, ice can't melt and water can't freeze, so we have a stable and unchanging system.

Interestingly, if you add heat (say, by putting the mixture in a warmer environment), the melting ice will absorb the added heat, keeping the mixture at 0C. If you remove heat (by putting the mixture in a colder environment), the freezing water will release heat, keeping the temperature of the mixture constant. As long as there's both water and ice mixed together, the temperature doesn't change.

Answer 2

Answer:

then there is a increase in volume and the density decreases.....
