Lesson 0 of 9
Start here
Show on a big screenHot tea in one hand, cold water in the other. This is hot. This is cold. But how hot? A hand cannot give a number.
This is Chapter 7, Temperature and its Measurement, in your NCERT book.
What you will learn
- A number for hot — a thermometer gives one number.
- Reading the scale — every mark is worth a fixed amount.
- Two thermometers — one for the body, one for experiments.
- Everyday numbers — weather and cold storage use the same number.
Need a quick recap?
- 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 thermometer stays on the screen.
