Describe in your own words the Kinetic Molecular Theory of gases. The Kinetic Molecular Theory of gases tells us that the energy content of any gas is related only to its temperature. It also tells us that it is possible to compute the "RMS" (root mean squared) velocity of any gas molecule if you know its formula weight and its temperature. Using this information describe how you might compute the RMS velocity of sulfur dioxide (SO2) in the atmosphere of the planet Venus (T = 820 F), the RMS velocity of oxygen (O2) in the atmosphere of Earth (T = 50 F), or the RMS velocity of carbon dioxide (CO2) in the atmosphere of Mars (T = - 80 F).

An atom of argon has a radius Ar = 71. pm and an average speed in the gas phase at 25°C of 249.m/s. Suppose the speed of an argon atom at 25°C has been measured to within 1.0%. Calculate the smallest possible length of box inside of which the atom could be known to be located with certainty. Write your answer as a multiple of Ar and round it to 2 significant figures. For example, if the smallest box the atom could be in turns out to be 42.0 times the radius of an atom of argon, you would enter "42. Ar" as your answer. Ar X ?

Archimedes tells us the lifting power of a balloon (how much mass it can lift) is equal to the difference between the mass of the balloon and the mass of the air it displaces. That is, if the balloon occupies the same volume as 10 kg of air, but the balloon only weighs 2 kg, then the gas density kg 0.090 3 m H, balloon can lift 8 kg. Airships have sometimes been filled with hydrogen (H,), but hydrogen is very flammable, and kg 0.18 Не m after the Hindenburg caught fire and crashed in 1937 with serious loss of life airships have nearly always been filled with helium (He) instead. kg 1.23 3 m' air Suppose a new airship Star of Balogna will have the shape of a cylinder 100. m long, with a radius of 15.0 m, and will weigh 9400. kg without any gas inside it. Suppose also the average passenger weighs 81 kg. Calculate how many passengers the Balogna could carry if it were filled with hydrogen, and also if it were filled with helium. Passengers with H,: Passengers with He:
