A spherical balloon of radius 3 cm containing helium gas has a pressure of $48 \times 10^{-3}$ bar. At the same temperature, the pressure, of a spherical balloon of radius 12 cm containing the same amount of gas will be ____ $\times 10^{-6}$ bar.
Show Answer
Answer: 750
Solution
$P_1V_1 = P_2V_2$; $P_2 = \frac{48 \times 10^{-3} \times (3)^3}{(12)^3} = 750 \times 10^{-6}$ bar.
