question_answer 1)

  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:

  (a) Shimla has lowest atmospheric pressure, hence liquidwill boil first in this city. Boiling of a liquid takes place, when the vapour pressure becomes equal to the atmospheric pressure.
