Consider the following statements.
(A) A bubble comes from the bottom of a lake to the top.
(B) Its radius increases.
Select the correct option.
(a) (A) is false, But (B) is true.
(b) Both (A) and (B) are true.
(c) (A) is true, But (B) is false.
(d) Both (A) and (B) are false.
air bubble comes up as air blows from high pressure region to top low pressure region.
As the air bubble obeys BOYLE'S Law and ideal gas equation as it moves up it radius increases and hence volume due to decrease in pressure.
