Is it true or false that water occurs in three forms: solid ice, liquid water, and water vapor?

The statement that water occurs in three forms—solid ice, liquid water, and water vapor—is indeed true. This concept relates to the physical states of matter, known as the phases of water.

In nature, water can be found in these three distinct forms depending on temperature and pressure conditions. Solid ice forms when water freezes at 0 degrees Celsius (32 degrees Fahrenheit) or lower, where the molecules become rigid and arranged in a crystalline structure. Liquid water is the most common state on Earth, existing between 0 degrees Celsius and 100 degrees Celsius (32 degrees to 212 degrees Fahrenheit) under normal atmospheric pressure. Water vapor is the gaseous state of water, occurring when water is heated beyond 100 degrees Celsius, allowing the molecules to move freely and disperse into the air.

This understanding is fundamental in various fields, including environmental science, meteorology, and engineering disciplines related to water management. The existence of water in these different forms is crucial for many natural processes, such as the water cycle, which includes evaporation, condensation, and precipitation.
