An airplane passenger has 99.7 cm³ of air in his stomach just before the plane takes off from a sea-level airport. What volume will the air have in cm at cruising altitude if
cabin pressure drops to 7.89 x 10 N/m²?
Type your answer...
The rate of change of atmospheric pressure P with respect to altitude h is
proportional to P, provided that temperature is constant. At 15°C the pressure is
101.3 kPa at sea level and 87.14 kPa at h = 1000 m. Answer the following
questions.
a) What is the atmospheric pressure at an altitude of 4000 m? Round to three decimal
places.
b) What is the atmospheric pressure at the top of Mount Greylock in Massachusetts, at
an altitude of 1063 m? Round to three decimal places.

The volume of an air bubble increases by a factor of 3.19 times as it rises from the bottom of a lake (density = 1000 kg/m 3). This is due to the drop of the absolute pressure by a factor of 1/3.19. Ignoring any temperature changes, What is the depth of the lake? Take g = 9.8 m/s2. One atmospheric pressure = 1.013 x 105 N/m2. Please round your answer to one decimal place.
Equation: ??ℎ+??=ρgh+Pa= 3.19 ??
