Water Study Guide
Definition of Water
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms.
Properties of Water
- Universal Solvent: Water is known as the universal solvent because it can dissolve a wide variety of substances.
- High Surface Tension: Water molecules are attracted to each other, creating a "skin" on the surface of the water.
- High Heat Capacity: Water can absorb a large amount of heat energy before its temperature rises significantly.
- Expansion Upon Freezing: Unlike most substances, water expands when it freezes, which is why ice floats on water.
Importance of Water
Water is essential for all forms of life. It is used for drinking, cooking, agriculture, and industrial processes. Additionally, water plays a crucial role in the water cycle, which regulates the Earth's climate and weather patterns.
Water Conservation
Given the importance of water, it is crucial to conserve and protect this valuable resource. Strategies for water conservation include reducing water usage, fixing leaks, and implementing sustainable water management practices.
