Welcome to NCTB Solutions. Here with this post we are going to help 6th class students by providing KSEEB Class 6 Science chapter 14 Solutions, Water. Here students can easily find all the answers for Water chapter. Also here our Expert Science Teacher’s solved all the exercise questions with easily understandable language with proper guidance so that all the students can understand easily. Here in this post students will get chapter 14 solutions. Here all the solutions are based on Karnataka State Board latest syllabus.
Water Exercise Questions Solutions :
(1) Fill up the blanks in the following :
(a) The process of changing of water into its vapour is called ____
(b) The process of changing water vapour into water is called ____
(c) No rainfall for a year or more may lead to ____ in that region.
(d) Excessive rains may cause ____
(2) State for each of the following whether it is due to evaporation or condensation :
(a) Water drops appear on the outer surface of a glass containing cold water.
The waters drops appear on the outer surface of a glass containing ice cold water because the water vapours present in the air is come in contact with the glass containing ice cold water and condenses and form water drops on the surface of a glass.
(b) Steam rising from wet clothes while they are ironed.
Yes due to evaporation because the process of changing of water into its vapour is called evaporation. And here the steam rising is the effect of evaporation
(c) Fog appearing on a cold winter morning.
Yes due to condensation fog appearing on a cold winter morning the process of changing water vapour into water is called condensation and fog falls down and change in water.
(d) Blackboard dries up after wiping it.
It dries because of evaporation because it change from water to vapour
(e) Steam rising from a hot girdle when water is sprinkled on it.
The steam rise because of the evaporation here the water change to vapour.
(3) Which of the following statements are “true”?
(a) Water vapour is present in air only during the monsoon.
(b) Water evaporates into air from oceans, rivers and lakes but not from the soil.
(c) The process of water changing into its vapour, is called evaporation.
(d) The evaporation of water takes place only in sunlight.
(e) Water vapour condenses to form tiny droplets of water in the upper layers of air where it is cooler.
(a) → False, because it is present all the time just because of temperature in summer it is less.
(b) → False, because evaporation is done every were but it is depend on the temperature.
(c) → True
(d) → False, because the evaporation takes where temperature is present.
(e) → True
(4) Suppose you want to dry your school uniform quickly. Would spreading it near an anghiti or heater help? If yes, how?
Firstly as we know that The process of changing of water into its vapour is called evaporation and if we want to dry school uniform it means that change water to vapour and for these change we need heat or temperature it helps in evaporation fast so we can dry the uniform by spreading it near an angrite or heater.
(5) Take out a cooled bottle of water from refrigerator and keep it on a table. After some time you notice a droplets of water around it. Why?
Because, firstly as we know that the process of changing water vapour into water is called condensation the surface of bottle gets cool means the air near bottle gets condensed hence the vapour change in water droplets.
(6) To clean their spectacles, people often breathe out on glasses to make them wet. Explain why the glasses become wet.
The people breathe out on glasses to make them wet because the air we breathe out makes the glass cool and because of condensation the glass gets wet.
(7) How are clouds formed?
Clouds are formed when the water vapour evaporates from the earth and collect at higher level of atmosphere.
For example : When you wash your clothes and keep it for drying in sunlight, the water from the clothes evaporates and clothes get dry. Evaporation is nothing but the formation of water vapour from the water. In the Same way the waters collects form various sources on entire earth and evaporates to higher level of atmosphere results to cloud formation.
(8) When does a drought occur?
Drought is the condition where there is no water in soil, lakes and wells etc. It is happen because of no rain occur for a year or two and by the evaporation the water is evaporated by the help of transpirations drought is no water condition in soil.
