    A cylinder with a movable piston contains air under a pressure P_1 and a soap bubble of radius 'r'. The pressure P_2 to which the air should be compressed by slowly pushing the piston into the cylinder for the soap bubble to reduce its radius by half will be : x[P_1 +3S//r] , where S is the surface tension
