If pressure of inside of the bubble more thereby it is expanded while two pressure are same.

For any curved surface of the bubble, the tension pulls parallel to the surface. These forces mostly cancel out, but create a net force inward. This compresses the gas inside the bubble, until the pressure inside is large enough to counteract both the outside pressure, as well as this additional force from the surface tension.

If pressure of inside the bubble is more then it will tend to expended then it is collapse due to pressure difference pressure always goes to high to low so according to this it will collapse.
