What is the role of the water?
Conclusion
Introduction
Among all liquid substances present on Earth, water is the most abundant and essential. Approximately 60–70 percent of the human body consists of water, which clearly indicates that life is impossible without it. Nearly two-thirds of the Earth’s surface is covered by water, while the remaining one-third is land inhabited by humans and countless other living organisms. Water plays a crucial role in sustaining life, and almost every activity in our daily lives depends directly or indirectly on water..jpeg "The Role and Importance of Water in Daily Life")
Properties of Water and Their Definition
The importance of water in daily life is immeasurable. Activities such as drinking, cooking, bathing, cleaning, and sanitation all require water. Some important physical and chemical properties of water are described below.
Melting Point and Boiling Point
In its solid state, water is known as ice. The temperature at which ice melts and turns into liquid water is called the melting point, which is 0°C.
The temperature at which liquid water changes into vapor is known as the boiling point. Under normal atmospheric pressure, the boiling point of water is approximately 100°C.
Pure water is colorless, odorless, and tasteless. The density of water varies with temperature and reaches its maximum value at 4°C, which is 1 g/cm³ or 1000 kg/m³.
What are 5 ways water is important to life?
Pure water does not conduct electricity. However, when salts, acids, or bases are dissolved in it, water becomes electrically conductive. Since water can dissolve most inorganic substances and many organic compounds, it is called a universal solvent. The pH value of pure water is 7, indicating neutrality.
Structure of Water
Therefore, the chemical formula of water is H₂O.
Sources of Water
Seas and oceans are the largest sources of water on Earth. About 97 percent of the total water is saline and unsuitable for drinking or daily use.
Approximately 2 percent of the Earth’s water is stored in glaciers and snowfields in the form of ice. The remaining usable freshwater—about 1 percent—comes from rivers, canals, wetlands, lakes, ponds, and groundwater. Groundwater is extracted using tube wells, while in hilly regions, melting snow gives rise to springs.
Sources of Freshwater in Bangladesh
In Bangladesh, rivers, canals, wetlands, ponds, and groundwater are the primary sources of freshwater. However, arsenic contamination has made groundwater unsafe in many areas. As a result, people in those regions are increasingly dependent on rainwater, which is used after proper purification.

Importance of Water for Aquatic Plants
Aquatic plants such as water hyacinth, duckweed, water lily, lotus, algae, water spinach, and helencha grow in water. Most aquatic plants cannot survive or reproduce without water. In the absence of water, severe ecological imbalance would occur.
Through photosynthesis, aquatic plants help maintain the level of dissolved oxygen in water and serve as a primary food source for aquatic animals. Instead of absorbing nutrients through roots alone, many aquatic plants absorb water and minerals through their entire body. Their stems and other organs are soft to adapt to their watery environment..jpeg "The Role and Importance of Water in Daily Life")
Water Quality Standards
Water is a precious natural resource, and maintaining its quality is essential. Poor water quality can cause serious harm to ecosystems and biodiversity.
Color and Taste
Pure water should be colorless and tasteless.
Turbidity
Turbid water prevents sunlight from penetrating, which disrupts photosynthesis and reduces dissolved oxygen levels.
Radioactive Substances
The presence of radioactive substances in water is extremely dangerous for aquatic plants, animals, and human health.
Dirt and Waste
Natural water sources should be free from dirt, waste materials, and disease-causing microorganisms.
Dissolved Oxygen
Dissolved oxygen is essential for aquatic life. A minimum of 5 milligrams of oxygen per liter of water is required for the survival of aquatic animals.
Temperature
Excessively high water temperatures reduce dissolved oxygen and disturb the normal life processes of aquatic organisms.
