Chapter 8 of Class 6 Science A Journey through States of Water explains how water exists in different states: solid, liquid, and gas. Chapter 8 introduces key processes such as evaporation, condensation, and the water cycle, and demonstrates how water changes state through heating and cooling. Through engaging activities and observations, students gain insight into these concepts, learn how water circulates between Earth’s surface and atmosphere, and understand the impact of various factors like temperature and humidity on the water cycle.

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.
FAQs on NCERT Solutions for Class 6 Science Chapter 8 A Journey Through States of Water
1. What are the main steps to solve NCERT questions from Class 6 Science Chapter 8 as per CBSE guidelines?
- Read the question carefully, noting any scientific terms about water states.
- Identify which process (evaporation, condensation, etc.) or concept the question is testing.
- Write your answer stepwise, using clear language and diagrams where needed.
- Review your answer to ensure it aligns with CBSE answer patterns.
2. According to NCERT Solutions for Class 6 Science Chapter 8, how can you distinguish between evaporation and condensation in practical situations?
- Evaporation occurs when liquid water turns to vapour due to heat, like when clothes dry in the sun.
- Condensation is when water vapour cools down and forms liquid droplets, as seen on a cold glass surface.
- Think about temperature changes and phase transitions to identify each process in daily life.
3. How does the water cycle demonstrate all three states of water as taught in Class 6 Science Chapter 8 NCERT Solutions?
The water cycle showcases water as a liquid (in rivers and oceans), a gas (as water vapour during evaporation), and a solid (such as ice or snow in colder areas). Each state is involved at different stages, illustrating transitions covered in NCERT Solutions for this chapter.
4. What factors affect the rate of evaporation according to NCERT Solutions for Class 6 Science Chapter 8?
- Temperature: Higher temperature increases evaporation.
- Air movement: Wind helps remove vapour, speeding up evaporation.
- Humidity: Low humidity increases evaporation.
- Surface area: Larger surface means faster evaporation.
5. In the context of CBSE Class 6 Science Chapter 8, how does evaporation cause a cooling effect?
Evaporation causes cooling because liquid water absorbs heat from its surroundings to change into vapour; this heat loss lowers the temperature of the nearby surface. That is why wet skin or earthen pots feel cooler as water evaporates from them.
6. What NCERT Solution method should be used to explain the change from ice to water and then to vapour?
Start by describing melting, where ice (solid) absorbs heat and turns into water (liquid). Further heating causes the water to undergo evaporation, forming water vapour (gas). Each step involves energy and state changes defined by heating.
7. Why is understanding condensation important for daily activities, according to Class 6 Science Chapter 8?
Condensation is important because it helps explain phenomena like dew formation, fog, and how clouds and rain occur. This knowledge aids in understanding weather patterns and everyday observations, as covered in NCERT Solutions for this chapter.
8. How can the knowledge of evaporation from NCERT Solutions for Class 6 Science Chapter 8 help you in real-life tasks?
- Speeding up drying of clothes by increasing airflow or exposing to sunlight.
- Storing water in earthen pots for natural cooling.
- Recognizing why sweat cools the body during hot weather.
9. What steps should be followed if a NCERT question asks for examples of water in its solid state in nature, as per CBSE format?
- Start with a direct answer: ice, snow, and frost are solid states of water in nature.
- Give one example for each if the question asks for more detail.
- Keep the answer concise, using keywords from the chapter.
10. What is a common misconception about the water cycle that CBSE Class 6 Science NCERT Solutions help to clarify?
A common misconception is that the water cycle only involves evaporation and condensation. NCERT Solutions clarify that precipitation (rain, snow, hail) and the role of surface run-off in the cycle are equally important steps.
11. Why is it important to conserve water, based on NCERT Solutions for Class 6 Science Chapter 8?
Only a small fraction of Earth's water is usable by humans. NCERT Solutions emphasize the importance of water conservation to ensure future availability and prevent scarcity, following the principle: 'Water is our responsibility before it is our right.'
12. What strategy should students follow to answer 'how to speed up evaporation' questions on CBSE exams, using NCERT Solutions tips?
Suggest increasing the temperature, spreading the liquid over a larger surface area, using a fan, or lowering the humidity — all strategies mentioned in NCERT Solutions for Class 6 Science Chapter 8.
13. How do Vedantu’s NCERT Solutions for Class 6 Science Chapter 8 support exam preparation?
- Stepwise, CBSE-aligned answers for every question in the chapter.
- Diagrams and examples that illustrate each process for clear understanding.
- Practice exercises that target commonly tested concepts and application-based questions.
14. What if a Class 6 Science NCERT Solution question asks about water cooling a hot object—what processes should be explained?
Explain that when water or a wet cloth is placed on a hot object (like a two-wheeler seat), evaporation of water absorbs heat from the seat, leading to cooling. Defend the answer using concepts from Chapter 8.
15. How does learning about states of water help in higher classes according to NCERT Solutions Class 6 Science Chapter 8?
Understanding states of water and phase transitions builds foundational knowledge for topics in chemistry (states of matter), physics (heat), and environmental science (water cycle) as students progress to higher grades following CBSE curriculum.
