FAQs on Water - Introduction Video Lecture - Science Class 6

1. What are the different states of water?
Ans. Water can exist in three different states - solid, liquid, and gas. In its solid state, water becomes ice, in its liquid state, it is the form we commonly see and use, and in its gaseous state, it becomes water vapor.
2. How does water change from one state to another?
Ans. Water changes its state from solid to liquid when heat is added, and from liquid to gas when heat is further increased. Similarly, water changes its state from gas to liquid when heat is removed, and from liquid to solid when it is further cooled.
3. How does water play a vital role in the environment?
Ans. Water is essential for the environment as it supports various ecosystems, provides habitats for aquatic plants and animals, and maintains the balance of temperature and weather patterns. It also plays a crucial role in the water cycle, where it evaporates from oceans and bodies of water, condenses in the atmosphere, and falls back to the Earth as precipitation.
4. What are the uses of water in our daily lives?
Ans. Water has numerous uses in our daily lives. We use it for drinking, cooking, bathing, washing clothes, and cleaning. Water is also used in industries, agriculture, and power generation. Additionally, it serves as a recreational resource for activities like swimming and boating.
5. How can we conserve water?
Ans. Water conservation is crucial to ensure its sustainable availability. We can conserve water by fixing leaky faucets and pipes, using water-efficient appliances, taking shorter showers, watering plants during cooler times of the day, and practicing responsible irrigation techniques. Additionally, spreading awareness about the importance of water conservation and implementing water-saving measures in industries and agriculture can contribute to preserving this valuable resource.
