Question: How many states can the common substance water exist in?

Water can exist in three common states: solid, liquid, and gas. These states are known as phases of matter and are determined by temperature and pressure.

1. Solid State (Ice): Water freezes and becomes ice at temperatures below its freezing point (0 degrees Celsius or 32 degrees Fahrenheit) at standard atmospheric pressure. In this state, water molecules are arranged in a fixed pattern, creating a solid structure.

2. Liquid State (Water): Water exists as a liquid at temperatures between its freezing point and boiling point (0 to 100 degrees Celsius or 32 to 212 degrees Fahrenheit) at standard atmospheric pressure. In this state, water molecules can move freely and take the shape of their container.

3. Gas State (Water Vapor): Water transitions to a gaseous state, known as water vapor, when heated to or above its boiling point (100 degrees Celsius or 212 degrees Fahrenheit) at standard atmospheric pressure. Water vapor molecules are more spread out and move rapidly.

These three states of water are fundamental examples of the different phases matter can assume based on temperature and pressure conditions.
