When a balloon is filled with air, the pressure inside the balloon is equal to the atmospheric pressure. A balloon is filled with 3.69 L of air on a nice summer day with an atmospheric pressure of 101.21 kPa. What would the volume of the balloon be if the atmospheric pressure dropped to 89.73 kPa (the level of a category 5 hurricane) with no change in temperature? 4.16 L 3.27 L 7.85 L 4.92 L

Answer the following questions: (a) Is the pressure of the gas in the hot air balloon shown at the opening of this chapter greater than, less than, or equal to that of the atmosphere outside the balloon? (b) Is the density of the gas in the hot air balloon shown at the opening of this chapter greater than, less than, or equal to that of the atmosphere outside the balloon? (c) At a pressure of 1 atm and a temperature of 20 C, dry air has a density of 1.2256 gt. What is the (average) molar mass of div air? (d) The average temperature of the gas in a hot air balloon is 1.30102 F. Calculate its density, assuming the molar mass equals that of div air. (e) The lifting capacity of a hot air balloon is equal to the difference in the mass of the cool air displaced by the balloon and the mass of the gas in the balloon. What is the difference in the mass of 1.00 L of the cool air in part (c) and the hot air in part (d)? (f) An average balloon has a diameter of 60 feet and a volume of 1.1105ft3. What is the lifting power of such a balloon? If the weight of the balloon and its rigging is 500 pounds, what is its capacity for carrying passengers and cargo? (g) A balloon carries 40.0 gallons of liquid propane (density 0.5005 g/L). What volume of CO2 and H2O gas is produced by the combustion of this propane? (h) A balloon flight can last about 90 minutes. If all of the fuel is burned during this time, what is the approximate rate of heat loss (in kJ/min) from the hot air in the bag during the flight?
A sealed-tube manometer (as shown below) can be used to measure pressures below atmospheric pressure. The tube above the mercury is evacuated. When there is a vacuum in the flask, the mercury levels in both arms of the U-tube are equal. If a gaseous sample is introduced into the flask, the mercury levels are different. The difference h is a measure of the pressure of the gas inside the flask. If h is equal to 6.5 cm, calclate the pressure in the flask in torr, pascals, and atmospheres.
A study of climbers who reached the summit of Mount Everest without supplemental oxygen showed that the partial pressures of O2 and CO2 in their lungs were 35 mm Mg and 7.5 mm Hg, respectively. The barometric pressure at the summit was 253 mm Hg. Assume the lung gases are saturated with moisture at a body temperature of 37 C [which means the partial pressure of water vapor in the lungs is P(H2O) = 47.1 mm Hg]. If you assume the lung gases consist of only O2, N2, CO2, and H2O, what is the partial pressure of N2?
A piece of dry ice (CO2(s)) has a mass of 22.50 g. It is dropped into an evacuated 22.50-L flask. What is the pressure in the flask at -4C?
A 20.0L stainless steel container at 25C was charged with 2.00 atm of hydrogen gas and 3.00 atm of oxygen gas. A spark ignited the mixture, producing water. What is the pressure in the tank at 25C? If the exact same experiment were performed, but the temperature was 125C instead of 25C, what would be the pressure in the tank?
A high altitude balloon is filled with 1041104 L of hydrogen at a temperature of 21 C and a pressure of 745 torr. What is the volume of the balloon at a height of 20 km. where the temperature is 48 C and the pressure is 63.1 torr?
