Question

An air bubble of volume 0.5cm^3 when released at the bottom of a lake rises to the surface of the lake explain why

Answer 1

Answer:

Explanation:

Boyle's law says

PV=RT

Here P is the pressure, V is the volume and T is the remperature. R is a constant. When T is constant

we get

PV=Constant.

When bubble is deep down it has water pressure and atmosphere pressure. As it raises, water pressure which is proportional to the depth, reduces. This will give V more. Volume increases.
