Q

How does the temperature affects water changing into different states

A

when the temperature changes, the state water remains unchanged ( 10-70 degrees the state of water remains as liquid) when the temperature remains unchanged the state of water changes like ( at 0 degree ice changes to water and water changes to ice ) and at 100 degree, water boils to steam.

Q

Name the process of water vapour or steam become liquid

A

condensation

17
Q

when water vapour comes into _____ with ______ surfaces it condenses into _______ then forms____ ____ .

A

contact , cold, water , water droplets

18
Q

example of condensation , taking a cold drink ( coke ) out of the fridge after some time you observe some water droplets on it , why?

A

The water vapour in air comes into contact. with the cold surface of the can and condenses into water which then forms water droplets on the can.

19
Q

example of condensation, when you boil a pot of water , there are water droplets on the glass lid of the pot, explain why.

A

when water boils, steam rises and comes into contact with the cold surface of the glass lid and condenses into water which then forms water droplets on the glass lid

20
Q

does water vapour or steam absorbs or releases energy? what is the process called?

A

releases, condensation.

21
Q

is steam visible?

A

no it is not

22
Q

what is the white mist above the boiling water?

A

tiny water droplets condensed near the steam .

23
Q

what is the name of the cycle water goes through in nature?

A

water cycle.

24
Q

where does the energy that powers the water cycle come from?

A

the Sun

25
Q

water in ___,______ and on ___ absorbs energy from the ___ and ________ to form ___ ____ . the _____ ____ is then carried upwards by ____ ___ beneath it .

A

seas, rivers , land ,Sun , evaporates ,water vapour , water vapour , warm air.

26
Q

What are the 2 main process of the water cycle?

A

Evaporation and condensation

27
Q

How are clouds formed?

A

The cold air in the sky cools the water vapour and it condenses to form water droplets which joins to form clouds.

28
Q

clouds may be carried to other places by____.

A

wind

29
Q

As more water vapour condenses, water droplets in the clouds grow _____and____. Eventually, they become so heavy that they fall as ___, ___, ___

A

larger, heavier,rain,snow,hail

30
Q

what factors affect the rate of evaporation

A
  1. temperature of surrounding

34
Q

does the rate of evaporation increase or decrease when there is wind?

A

increase

35
Q

does the rate of evaporation increase or decrease when the volume of water is low
