Question

Pressure inside two soap bubbles are 1 . 01 and 1 . 02 atmosphere, respectively. The ratio of their volumes is :, 4 : 1, 0 . 8 : 1, 8 : 1, 2 : 1

Excess pressure inside a soap bubble is 4 T R . Therefore, P 1 - P 0 = 4 T R 1 = 0 . 01 atm P 2 - P 0 = 4 T R 2 = 0 . 02 atm Dividing, 1 2 = R 2 R 1 ⇒ R 1 = 2 R 2 ⇒ V 1 V 2 = R 1 3 R 2 3 = 8 R 2 3 R 2 3 = 8 1
