Ascuba diver is 35 m below the surface of a lake, where the temperature is 5°c. he releases an air bubble with a volume of 18 cm3. the bubble rises to the surface, where the temperature is 25°c. assume that the air in the bubble is always in thermal equilibrium with the surrounding water, and assume that there is no exchange of molecules between the bubble and the surrounding water. what is the volume of the bubble right before it breaks the surface? hint: remember that the pressure also changes - this is a good time to review what you learned about the variation of pressure with depth in phys 4a.

An astronaut on the moon throws a baseball upward. the asatronaut is 6ft, 6in. tall, and the initial velocity of the ball is 30ft per second. the heigh s of the ball in feet is given by the equation s = -2.7^2 + 30t + 6.5, where t is the number of seconds after the ball was thrown. after how many seconds is the ball 16ft above the moon's surface?
