What is the value of FP for a sample of gas whose temperature is -33.0 C and volume is 0.0250 L? What temperature is required to change the volume to 66.9 cm3?
A hot-air balloon achieves its buoyant lift by heating the airinside the balloon, which makes it less dense than the air outside.Suppose the volume of a balloon is 1800 m3 and therequired lift is 2700 N (rough estimate of the weight of theequiptment and passenger). Calculate the temperature of the airinside the balloon which will produce the required lift. Assumethat the outside air temperature is 0 degrees C and that the air isan ideal gas under these conditions.How do I go about applying the ideal gas law to a problem like thiswhich asks me to factor in buoyant lift?Thanks!
To evaluate the use of renewable resources, an experiment was carried out with rice hulls. After pyrolysis, the product gas analyzed 6.4% CO2, 0.1% O2, 39% CO, 51.8% H2, 0.6% CH4, and 2.1% N2. It entered a combustion chamber at 90 °F and a pressure of 35.0 in. Hg and was burned with 40% excess air (dry) at 70 °F and an atmospheric pressure of 29.4 in. Hg; 10% of the CO remains. a. How many cubic feet of air were supplied per cubic foot of entering gas? b. How many cubic feet of product gas were produced per cubic foot of entering gas if the exit gas was at 29.4 in. Hg and 400 °F?
Calculate the density of combustion gases with the following composition: 75% N2, 5.5% O2 ,11% CO2, 84% H2O, and 0,1% CO. The temperature is 350 oF and the pressure is 755 mm Hg,
P1A.6 The molar mass of a newly synthesized fluorocarbon was measured in a gas microbalance. is device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. The beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10Torr; for the same setting of the pivot, a balance was reached when CHF3 (M = 70.014 g mol−1) was introduced at 423.22 Torr. A repeat of the experiment with a di erent setting of the pivot required a pressure of 293.22 Torr of the uorocarbon and 427.22 Torr of the CHF3. What is the molar mass of the fluorocarbon? Suggest a molecular formula.

One type of gas mixture used in anesthesiologyis a 50%/50% mixture (by volume) of nitrous oxide (N2O) and oxygen(O2), which can be premixed and kept in a cylinder for later use.Because these two gases don’t react chemically at or below 2000 psi, attypical room temperatures they form a homogeneous single gas phase,which can be considered an ideal gas. If the temperature drops below-6C, however, N2O may begin to condense out of the gas phase. Thenany gas removed from the cylinder will initially be nearly pure O2; asthe cylinder empties, the proportion of O2 will decrease until the gascoming from the cylinder is nearly pure N2O. In a hospital, pure oxygen may be delivered at 50 psi (gaugepressure) and then mixed with N2O. What volume of oxygen at 20Cand 50 psi (gauge pressure) should be mixed with 1.7 kg of N2O toget a 50%/50% mixture by volume at 20C? (a) 0.21 m3; (b) 0.27 m3;(c) 1.9 m3; (d) 100 m3

In another test, the valve of a 500 L cylinder full of the gas mixture at 2000 psi (gauge pressure) is opened wide so that the gas rushes out of the cylinder very rapidly. Why might some N2O condense during this process? (a) This is an isochoric process in which the pressure decreases, so the temperature also decreases. (b) Because of the rapid expansion, heat is…
