A diver 60 m deep in 10∘C fresh water exhales a 1.2-cm-diameter bubble.

What is the bubble's diameter just as it reaches the surface of the lake, where the water temperature is 20∘C

Assume that the air bubble is always in thermal equilibrium with the surrounding water.

Express your answer to two significant figures and include the appropriate units.
