A soda water bottle is falling freely , then the bubbles of the gas does not rise in the water of the bottle , why?

Asked by samagra Gupta 20th December 2015, 3:04 PM

The bubbles in a gas rise up due to buoyancy. There is an upthrust acting on the bubbles, due to the weight of the liquid they displace.

Now, when the bottle is in free fall, there is no gravity acting on the liquid, i.e. it is in a weightless condition.

Hence, there will be no upthrust on the bubbles and they do not rise.
