Problem 1: One end of a U-tube that contains water is open to the atmosphere, but the other end is closed. When some air is trapped in the closed end, the difference in the height of the water, h, shown in the figure, is 14.0 cm. Assume the outside air pressure is 0.960 atm. (a) What is the absolute pressure of the trapped air? h (b) What is the gauge pressure of the trapped air?
