A bubble of air is underwater at temperature `15^(@)C` and the pressure `1.5` bar. If the bubble rises to the surface where the temperature is `25^(@)C` and the pressure is `1.0` bar, what will happen to the volume of the bubble?

Options

A. Volume will become greater by a factor of 1.6.
B. Volume will become greater by a factor of 1.1.
C. Volume will become smaller by a factor of 0.70
D. Volume will become greater by a factor of2.5 .

Answer

A

Explanation

Given
`P_(1)=1.5` bar, `T_(1)=273+15=288K,V_(1)=V`
`P_(2)=1.0` bar `T_(2)=273+25=298k,V_(2)=?`
`V_(2)=1.55` V i.e., volume of bubble will be almost 1.6 times to initial volume of bubble.
