(i) Jammu has the largest difference in temperature i.e., Maximum temperature = 41°C and Minimum temperature = 26°C. Difference = 41°C – 26°C = 15°C (ii) Jammu is the hottest city due to maximum temperature is high and Bangalore is the coldest city due to maximum temperature is low. (iii) MaximumRead more
(i) Jammu has the largest difference in temperature i.e.,
Maximum temperature = 41°C and
Minimum temperature = 26°C.
Difference = 41°C – 26°C = 15°C
(ii) Jammu is the hottest city due to maximum temperature is high and Bangalore
is the coldest city due to maximum temperature is low.
(iii) Maximum temperature of Bangalore is 28°C
Minimum temperature of two cities whose minimum temperature is higher
than the maximum temperature of Bangalore are Ahemedabad and Jaipur
where the minimum temperature is 29°C
(iv) Mumbai has the least difference in temperature i.e.,
Maximum temperature = 32°C and
Minimum temperature = 27°C
∴ Difference = 32°C – 27°C = 5°C
