Air bubble formed in liquid is considered as a sphere of air .initiall

1.	Air bubble formed in liquid is considered as a sphere of air .initially ,bubble obtained acceleration is in upward direction and it is risingin liquid why ?
Answer» Solution :Air bubble formed in liquid obtained ACCELERATION in upward DIRECTION and it is rising in liquid , because the DENSITY of air bubble `(rho)` is less than density of liquid `(sigma).(rholtsigma)` HENCE TERMINAL velocity of bubble is negative and hence it rises in liquid.
