Water

Water is a clear, tasteless, odorless, and colorless chemical substance that is essential for all forms of life. It covers about 71% of the Earth's surface and is vital for the functioning of ecosystems and the survival of organisms.

Properties of Water:

• Universal solvent: Due to its polarity, water is capable of dissolving a variety of substances, earning it the title of "universal solvent".
• Surface tension: Water molecules are cohesive, meaning they are attracted to each other, which gives water a high surface tension.
• High specific heat: Water has a high specific heat capacity, which means it can absorb a lot of heat energy before its temperature rises significantly.
• Solid, liquid, and gas: Water exists in three states - solid (ice), liquid (water), and gas (water vapor).

Importance of Water:

Water is crucial for various processes and functions in living organisms, including:

• Hydration: Water is essential for maintaining proper hydration levels in the body.
• Transport: It serves as a medium for transporting nutrients and waste products within organisms.
• Temperature regulation: Water helps in regulating body temperature through sweating and respiration.
• Photosynthesis: Water is a key component in the process of photosynthesis in plants.
