A 1.9 cm*3 air bubble is released from the sandy bottom of a warm shallow sea, where the pressure is 2 atm. a) If the bubble rises slowly enough that it remains at the same constant temperature as the water what is the volume of the bubble when it reaches the surface, where the pressure is one ATM? Draw a PV diagram in a written work representing this process. b) As the bubble rises, is heat energy transferred from the water to the bubble or from the bubble to the water? Explain your answer. C) Now imagine that instead, the bubble rises very quickly, so it has no
