FAQs on A Journey through States of Water Video Lecture - Science for Class 6

1. What are the three states of water and how do they change from one to another?

Ans. The three states of water are solid (ice), liquid (water), and gas (water vapor). Water changes from solid to liquid when it melts, which occurs at 0°C. Conversely, it changes from liquid to solid when it freezes at 0°C. Liquid water becomes gas through evaporation when heated, occurring at any temperature, while gas condenses back into liquid water when cooled.

2. What is the water cycle and why is it important?

Ans. The water cycle is the continuous movement of water on, above, and below the surface of the Earth. It includes processes such as evaporation, condensation, precipitation, and runoff. The water cycle is important because it replenishes freshwater resources, supports ecosystems, and regulates climate by distributing heat around the planet.

3. How does temperature affect the state of water?

Ans. Temperature plays a crucial role in determining the state of water. At low temperatures (0°C and below), water exists as a solid (ice). As the temperature rises to 0°C, ice melts into liquid water. When the temperature reaches 100°C, water boils and transforms into water vapor. Thus, changes in temperature directly influence whether water is in a solid, liquid, or gaseous state.

4. What role does pressure play in the states of water?

Ans. Pressure affects the boiling and freezing points of water. At higher pressures, the boiling point of water increases, meaning it requires more heat to become vapor. Conversely, at lower pressures, such as at high altitudes, water boils at a lower temperature. This means that the state of water can change based on the surrounding pressure conditions.

5. Can water exist in more than one state at the same time?

Ans. Yes, water can exist in more than one state at the same time, a phenomenon known as the triple point. This occurs at a specific temperature and pressure where ice, liquid water, and water vapor can coexist. For water, this occurs at a temperature of 0.01°C and a pressure of 611.657 pascals.
