What is the rms speed of the molecules in low-density oxygen gas at 0 °C? (The mass of an oxygen molecule, O2, is 5.31 x 10-26 kg).
Answer to relevant Questions(a) What is the average kinetic energy per molecule of a monatomic gas at a temperature of 25 °C? (b) What is the rms speed of the molecules if the gas is helium? (A helium molecule consists of a single atom of mass 6.65 x ...If 2.0 mol of oxygen gas is confined in a 10-L bottle under a pressure of 6.0 atm, what is the average kinetic energy of an oxygen molecule? For an average molecule of N2 gas at 10 °C, what are its (a) Translational kinetic energy, (b) Rotational kinetic energy, and (c) Total energy? Repeat for He gas at the same temperature. The escape speed from the Earth is about 11 000 m/s (Section 7.5). Assume that for a given type of gas to eventually escape the Earth’s atmosphere, its average molecular speed must be about of the escape speed. (a) Which ...Many people have performed firewalking, in which a bed of red- hot coals (temperature over) is walked on with bare feet. (You should not try this at home!) How is this possible?
