Q.20A soap bubble of radius r0 = 2.0 mm floats freely inside a vacuum bell jar. The pressure inside the bell jar is originally p= 1 atm. The vacuum pump is turned on and the pressure in the bell jar is slowly decreased to zero while the temperature of the gas inside the bubble remains constant What is the radius of the soap bubble the soap bubble when the outside pressure drops to zero? The surface tension for a soap bubble is γ = 2.50 × 10-2 N/m. (see computer problem 1.)
