Q1.
During summer time you would have heard in the news that there is a ‘heat wave’. What do you think will be the temperature during the summer when you feel very hot?
Answer
On a heat-wave day the temperature usually crosses 45 °C.
- A normal hot summer day in most of India: about 38 °C to 42 °C.
- A heat wave is declared when the maximum goes far above the normal — often 45 °C or more.
- Places such as Churu (Rajasthan), Nagpur and Delhi have recorded around 48 °C to 50 °C.
Tip: All of these are positive temperatures — far above 0 °C, the freezing point of water. Negative temperatures come only in very cold places.
