How many cubic meters of helium are required to lift a light balloon with a 400-kg payload to a height of 8 000 m? Take Hc = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression pair = 0e-z/8 000, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.
The density of the atmosphere varies drastically with height, but you can use an average density from sea floor to the space in order to calculate its height. If we approximate this average density to be = 1 Kg/m³, what would be height of the atmosphere? HINT: Since the atmosphere is a fluid (in gas form), you can use the hydrostatic pressure formula (P pgh), just solve for h and use P = 1 atm. BTW, this is how the edge of space is defined, if you make it pass the height of the atmosphere you have reached space :)
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. CHECK ANSWER kPa NEXT kPa

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 ??
An airplane passenger has a volume V1 of air in his stomach just before the plane takes off from a sea-level airport. What volume will this quantity of air have at cruising altitude at the same temprerature ( body temp. ), in terms of V1, the pressure on the ground P1, and the cabin pressure at cruising altitude P2? What is this volume, in cubic centimeters, if the initial volume is 110 cm^3 and the cabin pressure drops to 7.5x10^4 Pa when the plane is at cruising altitude?
A submarine dives down to a depth 80 metres beneath the surface of the ocean. Calculate the pressure in atmospheres at that depth, assuming the density of water is 1029 kg/m3, and the air pressure at the surface is 105.2 kPa. Give your answer with two digits of precision. Note: 1 standard atmosphere is 101325 Pa. Your Answer: Answer
The density of air is 1.3 kg/m3 at sea level. From your knowledge of air pressure at ground level, estimate the height of the atmosphere. As a simplifying assumption, take the atmosphere to be of uniform density up to some height, after which the density rapidly falls to zero. (In reality, the density of the atmosphere decreases as we go up.)

Atmospheric pressure follows the following differential equation: dP/dh = −kP Where k is a constant that depends on other physical constants such as temperature, the acceleration of gravity, the molecular weight of air, etc. Suppose that the atmospheric pressure at sea level is 1013mb (millibars) and the atmospheric pressure in Mexico City, which is 2240m above sea level, is 764mb. Estimate the atmospheric pressure in the lagoons of Montebello, Chiapas, which are 1500m above sea level. Note: Don't skip steps to get to the result
