Why does an air bubble form in water grow in size from bottom when it rises ?

Text Solution

Verified by Experts

Pressure decreases from bottom to surface . Hence ,according to Boyle.s law `Vprop(1)/(P)` (At constant temperature) volume of bubble increases.

A small spherical monoatomic ideal gas bubble (gamma= (5)/(3)) is trapped inside a liquid of density rho_(l) (see figure) . Assume that the bubble does not exchange any heat with the liquid. The bubble contains n moles of gas. The temperature of the gas when the bubble is at the bottom is T_(0) , the height of the liquid is H and the atmospheric pressure is P_(0) (Neglect surface tension). When the gas bubble is at a height y from the bottom , its temperature is :-
