- True/False The particle transport loss due to diffusion in a circular tube is dependent on tube diameter and particle diffusivity.A Geiger-Muller tube is a type of gas-filled radiation detector. It can detect particles like X-rays, alpha particles, and beta rays (electrons). This is useful in quantizing the activity of a radioactive source or determining if an area containing radioactive material is safe to enter. If a Geiger counter is filled with 1 mol of argon gas at pressure P = 1.0620 × 10ª Pa and temperature T = 20.0 °C, what is the density p of the gas in this Geiger tube in grams per cubic centimeter? The atomic mass of argon is aa, = 39.948 g/mol. g/cm3Pls help on this question.
- An argon-40 atom has a mass of 6.64 ✕ 10−26 kg. (a) What temperature (in K) would a gas composed entirely of argon-40 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from Earth, 1.12 ✕ 104 m/s? K (b) What temperature (in K) would a gas composed entirely of argon-40 atoms have to be at in order for the rms speed of the atoms to equal the escape speed from the Moon, 2.37 ✕ 103 m/s? KLong-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.13 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 120-L tank at -45.0°C, what is the final pressure in the tank?
