Glance on Class 6 A Journey Through States of Water (Curiosity) Chapter 8

Evaporation: Conversion of water into vapour due to heating.
Condensation: Conversion of water vapour back into liquid form.
Water States: Water exists in three states - solid (ice), liquid (water), and gas (vapour).
Water Cycle: The continuous movement of water between Earth's surface and the atmosphere.
Factors Affecting Evaporation: Includes temperature, air movement, humidity, and exposed surface area.
Cooling Effect of Evaporation: Evaporation causes a cooling effect, which explains why water in earthen pots stays cool.
Precipitation: Water vapour condenses in the air to form clouds, leading to rainfall, hail, or snow.

Question 1. Which of the following best describes condensation?

(i) The conversion of water into its vapour state.

(ii) The process of water changing from a liquid into a gaseous state.

(iii) The formation of clouds from tiny water droplets.

(iv) The conversion of water vapour into its liquid state.

Answer: (iv) The conversion of water vapour into its liquid state describes condensation.

Question 2. Identify in which of the given processes, evaporation is very important

(i) Colouring with

(a) crayons

(b) watercolours

(d) pencil colours

(ii) Writing on paper with

(a) pencil

(b) ink pen

Answer:

(i) (b) watercolours

(ii) (b) ink pen

Question 3. We see green-coloured plastic grass in many places these days. Space around natural grass feels cooler than space around plastic grass. Can you find out why?

Answer: Natural grass cools the surrounding area by absorbing moisture from the air, unlike plastic grass, which does not absorb moisture.

Question 4. Give examples of liquids other than water, which evaporate.

Answer: Liquids like milk, oil, alcohol, eye drops, and sanitiser evaporate other than water.

Question 5. Fans move air around, creating a cooling sensation. It might seem strange to use a fan to dry wet clothes since fans usually make things cooler, not warmer. Normally, when water evaporates, it requires heat, not cold air. What do you think about this?

Answer: Fans help clothes dry faster by increasing air circulation, which speeds up the evaporation process, even though the fan itself may not produce heat.

Question 6. Usually, when sludge is removed from drains, it is left in heaps next to the drain for 3-4 days. Afterwards, it is transported to a garden or a field where it can be used as manure. This approach reduces the transportation cost of the sludge and enhances the safety of individuals handling it. Reflect upon it and explain how.

Answer: By leaving sludge out, the water in it evaporates, reducing its volume, and making it lighter and easier to handle and transport.

Question 7. Observe the activities in your house for a day. Identify the activities that involve evaporation. How does understanding the process of evaporation help us in our daily activities?

Answer: Activities involving evaporation include drying clothes in the sun, noticing the smell of food cooking without being in the kitchen, and wet utensils drying after washing. Understanding evaporation helps us speed up these processes.

Question 8. How is water present in the solid state in nature?

Answer: Water exists in its solid form in nature as ice, snow, and frost.

Question 9. Reflect on the statement “Water is our responsibility before it is our right.” Share your thoughts.

Answer: While we have a right to use water, only a small portion is usable. We must conserve and protect water sources to ensure future availability, as pollution and wastage threaten this resource.

Question 10. The seat of a two-wheeler parked on a sunny day has become very hot. How can you cool it down?

Answer: You can cool the seat by covering it with a wet cloth, sprinkling water on it, using a seat cover, or parking in the shade to reduce direct sunlight.

Sprinkle water on it: Lightly sprinkle water directly on the seat. The evaporating water will help to lower the temperature.

Use a sunshade or cover: If available, use a sunshade or seat cover to protect the seat from direct sunlight, which will help keep it cooler.

Park in the shade: If possible, move the two-wheeler to a shaded area to reduce the seat’s exposure to direct sunlight.

FAQs on NCERT Solutions for Class 6 Science Chapter 8 A Journey Through States of Water

1. What is evaporation and how is it explained in Class 6 Science Chapter 8?

Evaporation is the process where water changes into vapour due to heating. In Chapter 8 of "A Journey through States of Water," Vedantu’s NCERT Solutions explain this concept by demonstrating how water evaporates from different surfaces under various conditions.

2. How does condensation occur according to Chapter 8 of Class 6 Science?

Condensation is when water vapour cools and turns back into liquid water. Vedantu’s solutions for Chapter 8 detail this process and show how condensation forms clouds and precipitation.

3. What are the three states of water discussed in this chapter from Science Class 6?

Chapter 8 of "A Journey through States of Water" covers water in three states: solid (ice), liquid (water), and gas (vapour). The NCERT Solutions provided by Vedantu help students understand these states and their transitions.

4. How does the water cycle work as per Chapter 8 A Journey through States of Water?

The water cycle involves the continuous movement of water between the Earth’s surface and the atmosphere through processes like evaporation, condensation, and precipitation. Vedantu’s solutions for Chapter 8 explain this cycle with diagrams and examples.

5. What factors affect the rate of evaporation, from the Class 6 Science Chapter 8?

Factors such as temperature, air movement, humidity, and exposed surface area influence the rate of evaporation. Vedantu’s NCERT Solutions for Chapter 8 provides detailed explanations and examples.

6. Why does evaporation cause a cooling effect from A Journey through States of Water?

Evaporation causes a cooling effect because it requires heat energy to convert water into vapour. Vedantu’s solutions in Chapter 8 illustrate this concept with practical examples like water in earthen pots.

7. What observations can be made from the activity involving ice and water?

The activity shows that ice melts into water, demonstrating that ice and water are the same substance in different states. Vedantu’s solutions in Chapter 8 help students understand this transformation and its implications.

8. How do clouds form according to Chapter 8?

Clouds form when water vapour in the air condenses into tiny droplets. Vedantu’s NCERT Solutions for Chapter 8 explains this process and its role in the water cycle.

9. What is the significance of the water cycle in environmental science?

The water cycle is crucial for maintaining Earth’s water balance and supporting life. Vedantu’s Chapter 8 solutions highlight the importance of this cycle in understanding weather patterns and ecological balance.

10. How do Vedantu’s NCERT Solutions help with understanding the states of water?

Vedantu’s solutions for Chapter 8 provide clear explanations, diagrams, and practical examples to help students grasp the concepts of water’s states, their transitions, and the water cycle effectively.
