##### Following number line shows the temperature in degree Celsius(oC) at different places on a particulars 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?

(a) By observing the above given data, we can represent the temperature of cities as follows:

 Cities Temperature Lahulspiti -8oC Srinagar -2oC Shimla 5oC Ooty 14oC Bangalore 22oC

(b) From the above table it is clear that:

Hottest place temperature = 22oC

Coolest place temperature = -8oC

Therefore,

Temperature diference = Hottest place temperature – Coolest place temperature

= 22 – (-8)

= 30oC

Hence,

Temperature between the hottest and coolest place is 30oC

(c) From the above table it is clear that:

Temperature of Lahulspiti = -8oC

Temperature at Srinagar = -2oC

Therefore,

Temperature difference of both cities = Temperature of Lahulspiti - Temperature of Srinagar

= -8 – (-2)

= -8 + 2

= 6oC

Hence,

The temperature difference between Lahulspiti and Srinagar is 6oC

(d) From the above table it is clear that:

Temperature of Srinagar = -2oC

Also,

Temperature of Shimla = 5oC

Therefore,

Temperature of Srinagar and Shimla taken together = -2 + 5

= 3oC

Since,

3oC < 5oC

3oC < Temperature of Shimla

It is clear that temperature of Srinagar and Shimla taken together is less than the temperature of Shimla
