A spherical balloon of radius 3cm3cm containing helium gas has a pressure of 48×10−348 \times {10}^{- 3} bar. At the same temperature, the pressure, of a spherical balloon of radius12cm12cm containing the same amount of gas will be………….×10−6\ldots \ldots \ldots \ldots . \times {10}^{- 6} bar.

Correct answer

750

Step-by-step solution

if volume of 3cm3cm balloon is =V= V
then volume of 12cm12cm radius balloon =64V= 64V
So pressure will become 1/641 / 64 times =1/64×48×10−3= 1 / 64 \times 48 \times {10}^{- 3} bar =750×10−3= 750 \times {10}^{- 3} bar
