Answers
Answer:
Step-by-step explanation:
Following number line shows the temperature in degree celsius (°C) at different places on a particular day.
(A) Observe this number line and write the temperature of the places marked on it.
(B) What is the temperature difference between the hottest and the coldest places among the above?
(C) What is the temperature difference between Lahulspiti and Srinagar?
(D) Can we say temperature of Srinagar and Shimla taken together is less than the temperature at Shimla? Is it also less than the temperature at Srinagar?
SOLUTION:
(A) The temperatures of the cities are as follows : Lahulspiti : –8°C; Srinagar : – 2°C; Shimla : 5°C; Ooty : 14°C; Bangalore : 22°C
(B) Temperature at the hottest place, i.e., Bangalore= 22°C
Temperature at the coldest place, i.e., Lahulspiti= – 8°C.
\ Temperature difference = 22° – (–8°C) = 30°C
(C) Temperature at Lahulspiti = – 8°C; Temperature at Srinagar = – 2°C
\ Temperature difference = – 2°C – (–8°C) = 6° C
(D) Temperature at Srinagar = – 2°C; Temperature at Shimla = 5°C
Temperature of Srinagar and Shimla taken together = – 2°C + 5°C = 3°C
Hence, the temperature of Srinagar and Shimla taken together is less than the temperature of Shimla but greater than the temperature of Srinagar.
