Question

Statement 1: When two soap bubbles having different radii are kept in contact, the common surface at their interface bulges into the larger bubble.
Statement 2: Pressure inside the smaller bubble is larger.

• A. Statement $-1$ is true, Statement $-2$ is false
• B. Statement $-1$ is false, Statement $-2$ is true
• C. Statement $-1$ is true, Statement $-2$ is true and Statement $-2$ is a correct explanation for Statement1.
• D. Statement $-1$ is true, Statement $-2$ is true but Statement $-2$ is not a correct explanation for Statement $-1$

Answer 1

Answer: (C)

Statement $-1$ is true, Statement $-2$ is true, and
Statement $-2$ is a correct explanation for Statement $-1.$
Pressure inside a bubble $\propto \frac{1}{\text{ radius }}$
as $P=\frac{4T}{r},$ where $T$ is the surface tension.
