An air bubble of

20 \text{ cm}^3

volume is at the bottom of a lake 40 m deep where the temperature is

4^{\circ}\text{C}

. The bubble rises to the surface which is at a temperature of

20^{\circ}\text{C}

. Take the temperature to be the same as that of the surrounding water and find its volume just before it reaches the surface.
