- A particle on the surface of the Earth can "escape" the Earth's gravitation and continue to move away from the Earth forever, if it has a sufficient speed (called the escape speed). (a) Determine the escape speed (in m/s) if the particle is an oxygen molecule. Use 6.37 x 106 m for radius of the Earth. m/s (b) Determine the temperature (in K) at which the rms speed of the oxygen molecule is 13 times the escape speed. T = K (c) What If? The Universe is composed of 75% hydrogen and 25% helium by mass, yet these gases are not found in the Earth's atmosphere. Calculate the temperatures (in K) for which the minimum escape kinetic energy is nine times the average kinetic energy of hydrogen (H₂) molecules and helium atoms. K K TH2 THE(a) Hydrogen molecules (molar mass is equal to 2.016 g/mol) have vrms equal to 193 m/s. What is the temperature? (b) Much of the gas near the Sun is atomic hydrogen (H rather than H2). Its temperature would have to be 1.5 × 107 K for the rms speed vrms to equal the escape velocity from the Sun. What is that velocity?Please Asap
- The atomic and molecular rms speeds of gases, vrms, are usually quite large, even at low temperatures. What is vrms, in meters per second, for helium atoms at 5.85 K (which is close to the point of liquefaction)?Nitrogen is released at one end of a pressure chamber of length 30 meters and takes 7 hours and 44 minutes to diffuse from one end of the chamber to the other. Given that the mean radius of a nitrogen molecule is 0.15 nm, and the chamber is at room temperature (∼300 K), determine the pressure to which the chamber was set (in atm).Much of the gas near the Sun is atomic hydrogen. Its temperature would have to be 1.50 107 K for the average speed vrms to equal the escape speed of the Sun. What is that speed? The atomic mass of hydrogen is 1.008 10-3 kg/mol.
