What will happen to the volume of a bubble of air found underwater in a lake, where the temperature is 15 o C and the pressure is 1.5 atm, if the bubble then rises to the surface where the temperature is 25 o C and the pressure is 1.0 atm?

Question

What will happen to the volume of a bubble of air found underwater in a lake, where the temperature is 15 o C and the pressure is 1.5 atm, if the bubble then rises to the surface where the temperature is 25 o C and the pressure is 1.0 atm?, Its volume will become greater by a factor of 2.4, Its volume will become greater by a factor of 1.55, Its volume will become greater by a factor of 1.2, Its volume will become smaller by a factor of 0.80

P 1 V i T 1 = P 2 V f T 2 V f = P 1 T 2 P 2 T 1 . V f V i = volume of water bubble under water V f = volume of water bubble at the surface V f = 1.5 × 298 V i 1 × 288 = 447 288 V i = 1.55 Vi The volume becomes greater by a factor of 1.55.
