Question

Atmospheric pressures recorded in different cities are as follows:

Cities	Shimla	Bangalore	Delhi	Mumbai
$p$ in $N/m^2$	$1.01\times {10}^5$	$1.2\times {10}^5$	$1.02\times {10}^5$	$1.21\times {10}^5$

Consider the above data and mark the place at which liquid will boil first.

• A. Shimla
• B. Bangalore
• C. Delhi
• D. Mumbai

Answer 1

The correct option is A Shimla

The boiling point of a liquid is the temperature at which vapour pressure becomes equal to the atmospheric pressure. Lower the atmospheric pressure, lower is the boiling point.

Since the atmospheric pressure of the Shimla is minimum, thus the boiling point of the liquid will be lowest at Shimla.
