A bubble of air is underwater at temperature 15^ C and the pressure 1.5 ~bar . If the bubble rises to the surface where the temperature is 25^ C and the pressure is 1.0 ~bar , what will happen to the volume of the bubble?

Options

  1. AVolume will become greater by a factor of 1.6
  2. BVolume will become greater by a factor of 1.1
  3. CVolume will become smaller by a factor of 0.70
  4. DVolume will become greater by a factor of 2.9

Correct answer

A. Volume will become greater by a factor of 1.6

Step-by-step solution

p₁ V₁ T₁ = p₂ V₂ T₂ (By ideal gas equation) or 1.5 V₁ 288 = 1 V₂ 298 V₂=1.55 V₁ i.e., volume of bubble will be almost 1.6 times to initial volume of bubble.
