Realize the range of water and it's phase changes.

This is a fairly simple chart of the "Phases of Water."

The most common phase of water is liquid. It is what most people think of when water is discussed. We cook with it. We bath in it. We drink it.

The temperature of liquid water is between and not including 0 degrees Celsius (C) and 100 degrees Celsius. Or. 32 degrees Fahrenheit (F) to 212 degrees Fahrenheit.

The next phase most people think of is solid. Ice. Ice forms when temperatures reach below 32 F or 0 C.

The least appreciated phase of water is greater than 212 F or greater than 100 C. This is water vapor.

Water also has weight which for a gallon of room temperature water (liquid phase) weighs 8.33 pounds.

Two of the phases mentioned in the diagram not yet discussed is sublimation and deposition.

Sublimation is when water is solid and immediately turns to water vapor without going through a liquid phase

Deposition is when water goes through a phase change of gas to solid without going through a liquid phase.

All these phases of water occur on Earth.
