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 happens to water when it is compressed at a temperature below freezing?

• It becomes denser.

• It evaporates.

• It melts.

• It remains a solid.

In a phase diagram, what happens to water at normal atmospheric pressure when it is cooled?

• It turns into a gas.

• It remains a liquid.

• It becomes a solid.

• It becomes denser.

What prevents all the water from freezing in a container when it is below 0 degrees Celsius?

• The presence of impurities in the water.

• The temperature of the environment.

• The expansion of ice creating pressure.

• The container's material.

What is the result when water freezes into ice three?

• It contracts and becomes denser.

• It expands and becomes less dense.

• It remains the same density.

• It turns into a gas.

How does the phase of water change when both temperature is low and pressure is high?

• It turns into a gas.

• It remains a liquid.

• It freezes into a different phase of ice.

• It becomes a supercooled liquid.
