Question

The temperature in each city was noted at 3 pm on 16 January 2008.



(1) Which place had the highest temperature at 3 pm? Which place is the coolest at that time?
(2) How much higher is the temperature in Mumbai from that in Srinagar?
(3) How many degrees will the temperature need to rise for it to reach 40°C in Thiruvananthapuram?
(4) How much lower is the temperature of Kolkata from that in Chennai?
(5) The temperature in these cities was also noted at 3 am on the same day. Look at the table and answer the questions.
(a) Which place had the lowest temperature at 3 am? Imagine yourself to be there and describe how it would feel.
(b) What is the difference between the temperatures at 3 pm and 3 am in Chennai? In Bhopal?

City	Temperature at 3 am
Chennai	21.1
Mumbai	19.0
Th'puram	21.6
Kolkata	13.1
Bhopal	9.8
Srinagar	1.3
Guwahati	12.8
Jaipur	10.2

Answer 1

(1) Mumbai had the highest temperature i.e. 35.1°C at 3 pm. Srinagar was the coolest place with the temperature of 8.1°C at 3 pm.

(2) Temperature of Mumbai at 3 pm = 35.1^∘C
Temperature of Srinagar at 3 pm = 8.1^∘C
Difference in temperature = 35.1^∘C − 8.1^∘C
= 27^∘C

(3) Temperature of Thiruvananthapuram at 3 pm = 33.5^∘C
Rise in the temperature needed to attain a temperature of 40^∘C = 40^∘C − 33.5^∘C
= 6.5^∘C

(4) Temperature of Chennai at 3 pm = 29.9^∘C
Temperature of Kolkata at 3 pm = 26.6^∘C
Difference between temperature = 29.9^∘C − 26.6^∘C
= 3.3^∘C
(5)
(a) Temperature of Srinagar at 3 am = 1.3^∘C
It will be very cold there.

(b) Temperature of Chennai at 3 pm = 29.9^∘C
Temperature of Chennai at 3 am = 21.1^∘C
Difference between temperature = 29.9^∘C − 21.1^∘C
= 8.8^∘C

Temperature of Bhopal at 3 pm = 25.9^∘C
Temperature of Bhopal at 3 am = 9.8^∘C
Difference between temperature = 25.9^∘C − 9.8^∘C
=16.1^∘C
