Freezing water expands. What if you don't let it?

The video explores the unique properties of water, focusing on its behavior under pressure and temperature changes. It explains why ice floats and how water expands when frozen, leading to a paradox when trying to freeze it under pressure. The phase diagram of water is used to illustrate how water transitions between solid and liquid states under varying conditions. The video concludes by discussing different phases of ice, such as ice three, which contracts and becomes denser, resolving the paradox of freezing water in a fixed volume.

What occurs to the percentage of ice and liquid water as the temperature decreases in a fixed volume of water?

Describe the different phases of ice that can form under varying conditions of temperature and pressure.
