What will happen to the volume of a bubble of air found underwater in a lake, where the temperature is $15^{o} C$ and the pressure is 1.5 atm, if the bubble then rises to the surface where the temperature is $25^{o} C$ and the pressure is 1.0 atm?

Options:

Answer:

Solution:

$\frac{P_{1} V_{i}}{T_{1}} = \frac{P_{2} V_{f}}{T_{2}}$
$V_{f} = \frac{P_{1} T_{2}}{P_{2} T_{1}} . V_{f}$
$V_{i} =$ volume of water bubble under water
$V_{f} =$ volume of water bubble at the surface
$V_{f} = \frac{1.5 \times 298 V_{i}}{1 \times 288} = \frac{447}{288} V_{i = 1.55 Vi}$
The volume becomes greater by a factor of 1.55.
