A air bubble is released from the sandy bottom of a warm, shallow sea, where the gauge pressure is 1.5 atm. The bubble rises slowly enough that the air inside remains at the same constant temperature as the water.

a. What is the volume of the bubble as it reaches the surface?

b. As the bubble rises, is heat energy transferred from the water to the bubble or from the bubble to the water? Explain.
