Water is H2O

Only Substance on Earth that Occurs Naturally in 3 forms:
Solid, Liquid, & Gas

 3 states of water

Solid

• Ice is frozen water.

Solid Water Molecules:

When water freezes, its molecules move farther apart, making ice less dense than water. This means that ice will be lighter than the same volume of water, and so ice will float in water.

When Does Water Freezes?

Water freezes at 0° Celsius, 32° Fahrenheit.

Liquid
