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:

Answer:

Solution:

We know that from ideal equation,
$V \propto \frac{T}{P}$
Given $T_{1} = 15 + 273 = 288, P_{1} = 1.5$ bar
$T_{2} = 25 + 273 = 298, P_{2} = 1$ bar
$V_{1} \propto \frac{288}{1.5} i . e . V_{1} \propto 192$ and $V_{2} \propto \frac{298}{1}$
$\frac{V_{2}}{V_{1}} = \frac{298}{192} = 1.55 ≅ 1.6$
