An air bubble underwater has the same pressure as that of the surrounding water. As the air bubble rises toward the surface (and its temperature remains constant), the volume of the air bubble. a) increase or decrease, depending on the rate it rises.
b) decreases.
c) increases.
d) remains constant

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

The passage that directs air to the lungs is called a. diaphragm. b. larynx. c. bronchi. d. pharynx.
