Answer 2

H2O is the chemical formula for water. It represents a molecule composed of two hydrogen atoms bonded to one oxygen atom. Water is a vital substance for all known forms of life and is essential for various biological processes. It is also a universal solvent, meaning it has the ability to dissolve a wide range of substances.

Water exists in three states: solid (ice), liquid (water), and gas (water vapor). The state of water depends on the temperature and pressure conditions. At standard temperature and pressure, water is a liquid. It freezes into ice at temperatures below 0 degrees Celsius and boils into water vapor at temperatures above 100 degrees Celsius.

Water has many unique properties that make it essential for life. It has a high specific heat capacity, which means it can absorb and store a significant amount of heat without a large increase in temperature. This property helps regulate the Earth's climate and maintain stable temperatures in aquatic environments.

Water also has a high heat of vaporization, meaning it requires a large amount of heat energy to change from a liquid to a gas. This property allows water to act as a coolant in various biological processes, such as sweating in humans and transpiration in plants.

Furthermore, water exhibits cohesion and adhesion, which allow it to form droplets and capillary action. Cohesion refers to the attraction between water molecules, while adhesion refers to the attraction between water molecules and other substances. These properties enable water to move through plants and provide nutrients to cells.

In summary, H2O is the chemical formula for water, a vital substance for life with unique properties that make it essential for various biological processes.
