question_answer 1)

Following is the list of temperatures of five places in India on a particular day of the year:

Place	Temperature
Siachin	\[{{10}^{o}}C\] below \[{{0}^{o}}C\]	?????
Shimla	\[{{2}^{o}}C\] below \[{{0}^{o}}C\]	?????
Ahmedabad	\[{{30}^{o}}C\] above \[{{0}^{o}}C\]	?????
Delhi	\[{{20}^{o}}C\]above \[{{0}^{o}}C\]	?????
Srinagar	\[{{5}^{o}}C\] below \[{{0}^{o}}C\]	?????

(a) Write the temperatures of these places in the form of integers in the blank column. (b) Following is the number line representing the temperature in degree Celsius Plot the name of the city against its temperature. (c) Which is the coolest place? (d) Write the names of the places, where temperature are above \[{{10}^{o}}C\]. TIPS Temperature below \[{{0}^{o}}C\] is denoted with negative (-) sign and temperature above \[{{0}^{o}}C\]is denoted with positive (+) sign.

Answer:

(a)

Place	Temperature	Form of integers
Siachin	\[{{10}^{o}}C\]below \[{{0}^{o}}C\]	\[-{{10}^{o}}C\]
Shimla	\[{{2}^{o}}C\]below\[{{0}^{o}}C\]	\[-{{2}^{o}}C\]
Ahmedabad	\[{{30}^{o}}C\]above\[{{0}^{o}}C\]	\[+{{30}^{o}}C\]
Delhi	\[{{20}^{o}}C\]above\[{{0}^{o}}C\]	\[+{{20}^{o}}C\]
Sringar	\[{{50}^{o}}C\]below\[{{0}^{o}}C\]	\[-{{5}^{o}}C\]

(b) The name of city against its temperature on the number line is given below (c) After checking the temperature of all places, we can say that the Siachin \[(-{{10}^{o}}C)\] is the coolest place. (d) Delhi \[(+{{20}^{o}}C)\]and Ahmedabad \[(+{{30}^{o}}C)\]are the places, where temperature is above \[{{10}^{o}}C\].
