(a) Water vapour is present in the air only during the monsoon.

Ans: False

(b) Water evaporates into the air from oceans, rivers and lakes but not from soil.

Ans: False

(c) The process of water changing into its vapour is called evaporation.

Ans: True

(d) The evaporation of water takes place only in sunlight.

Ans: False

(e) Water vapour condenses to form tiny water droplets of water in the upper layers of air where it is cooler.

Ans: True

4. Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how?

Ans: Yes, to dry school uniform quickly, spreading it near an anghiti or heater will help. Anghiti or heater provides heat which increases the evaporation rate and as a result, the school uniform dries quickly.

5. Take out a cooled bottle of water from the refrigerator and keep it on a table. After some time, you notice a puddle of water around it. Why?

Ans: We see a pool of water after a while when we take a cooled bottle of water from the refrigerator and place it on a table. This happens due to the condensation process. The water vapour condenses out due to low temperature around the bottle and droplets of water are seen.

6. To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet?

Ans: The glasses become wet due to the breath because of condensation. The air which we breathe out contains carbon dioxide and moisture which condense due to lower temperature and wet the glass.

7. How are clouds formed?

Ans: The water present on the earth forms water vapour because of evaporation. The water vapour then mixes with the air which due to an increase in the temperature, takes the water vapour in the upward direction. At higher altitudes, the temperature of the water vapour decreases which on cooling forms water droplets in the air referred to as clouds.

8. When does a drought occur?

Ans: Drought is a phenomenon that occurs due to the scarcity of rainwater. It occurs in places that lack rainfall. As a result, underground water is not restored and soil loses its moisture due to evaporation.

## NCERT Solutions for Class 6 Science Chapter 14 Water

Science NCERT Grade 6, Chapter 14, Water notably covers the fundamental basics related to water. It begins with bringing up some primary uses of water in each day's life. Thereafter, an estimation of the quantity of water used each day is measured using an activity. Next, the one-of-a-kind sources of water like lakes, ponds, rivers, and oceans are cited. Subsequently, a few very essential principles just like the water cycle, and cloud formation are comprehensively included via activities. This part additionally provides a definition of the term rain and mentions evaporation and transpiration as an integral part of the water cycle.

Subsequently, one of a kind ways in which water falls down on the land - snow, rainwater, etc is explained.

The term groundwater is illustrated in the chapter, Water. In the later sections, the two extreme situations of water abundance and water shortage are mentioned as floods and drought respectively. It discusses various after-effects of drought and flood and the way they lead to loss of life and property.

Furthermore, the chapter, water discusses several techniques for the conservation of water. This chapter targets to create awareness about the conservation of water. The chapter lays emphasis on the idea of rainwater harvesting towards the end.

The topics included in the chapter, ​Water are -

• How Much Water Do We Use?

• Where Do We Get Water From?

• Water Cycle, Back To The Oceans

• What If It Rains Heavily?

• How Can We Conserve Water?

• What Happens If It Does Not Rain for a Long Period?

• Rainwater Harvesting

### Use of Water

It is evident that water is vital for our Earth, and without it, life wouldn't have existed. Our planet Earth is a huge reservoir of water as three-fourth of the surface is covered with water.

However, only 2.6% of freshwater is available out of the total water. Water is a renewable source, but in the recent past, there has been a sharp increase in its wastage and usage. This may lead to freshwater as a scarce resource in the future. Water is used for numerous purposes in daily life like cooking, washing, and, of course, drinking. The study of Water Class 6 will help students learn the chapter with a detailed approach.

### The Source of Water

There are numerous sources of water. It depends on the various sources from where people find it easy to get access to water. These include ponds, lakes, wells, rivers, seas and oceans. Sometimes, the water sources are not appropriate for drinking, and thus, water is fetched from these sources and then purified in various plants to make it appropriate for drinking. NCERT Class 6 Science Chapter 14 Water defines how people in urban areas and villages use and drink water.

### Water Cycle

Wells provides underground water, which is abundantly available. Even ponds, rivers and lakes are prime sources of water for living beings. However, rivers dry in specific places due to various reasons like the construction of dams, excess usage of water or lack of rainfall. This is why Class 6 Science Chapter 14 focuses on the water cycle.

It is the process of evaporation and condensation that makes living a lot easier and simpler. Evaporation is the main process of converting water into a gaseous state (in the form of vapour). Condensation is the process of converting the vapours into water molecules. Due to immense heat, water from various sources on Earth evaporates over a specific period. The water in the gaseous state forms clouds, which, in turn, condenses and brings all the water back to land. This cycle is known as the water cycle. NCERT Solutions for Class 6 science will provide a more in-depth insight into the concept.

### Transpiration

Ncert Class 6 Science Chapter 14 states that transpiration is the process through which water evaporates from the surface and rises into the atmosphere. Plants also contribute to the water cycle. With the help of the water cycle, it is possible to make use of the ocean water. Due to the saline nature of ocean water, using it directly from the source is not possible. The water that evaporates separates from salt to form clouds in the air. When the warm air rises into the atmosphere, the cold air above forces the occurrence of saturation and condensation to form water droplets.

The accumulation of clouds causes rainfall over vast sources of water on Earth. Rainfall fills up the sources like over lakes, ponds, and rivers to satisfy human and animal needs. The rainwater is also absorbed by the soil to feed the groundwater sources. To learn more about the continuous process of the water cycle, consider referring to NCERT Science book Class 6 Chapter 14 solutions.

### States of Water

The ice from the refrigerator or the snow in the peaks is nothing else but water in the solid-state. Humans can make ice by refrigerating water kept inside a freezer. Snow is available in the natural form, and it occurs in areas that are prone to extremely cold winters. The little droplets of water in the clouds shower in the form of snow.

The water that is normally available through taps is in the liquid state. We consume water in the liquid state.

The gaseous state of water is widely referred to as water vapour or steam. Water vapour is naturally available in the air. As it is odourless and colourless, we cannot smell or see water vapour. However, steam can be made by humans and can be even seen if it comes out in a large amount. Consider boiling water in a beaker, and it becomes too hot, you can see steam coming out from the water. Water chapter Class 6 defines clearly about each state of water, which is available in the PDF file.
