Lesson 0 of 9
Start here
Show on a big screenA white curl rises from a hot cup of chai. It fades into the air. Where does it go?
The curl is tiny drops of water. They turn into invisible vapour.
This is Chapter 8 of your NCERT book. It is A Journey through States of Water.
What you will learn
- Three forms, one water — ice, water and vapour are one water.
- Heat changes the form — warming and cooling move water between forms.
- The water cycle — the same water goes round and round.
Need a quick recap?
- A number for hot (in Temperature and its Measurement). A thermometer gives a number in °C.
- Hot, cold, or just used to it? (in Track Zero). Your hand is not a good thermometer.
Stay safe
Nothing here needs real heat or cold. Every cup and pot stays on the screen.
