Some incandescent light bulbs are filled with argon gas. What is Vrms for argon atoms near the filament, assuming their temperature is 2950 K? The atomic mass of argon is 39.948 u. 1578.9 X The number of grams per mole is numerically the same as the value measured in atomic mass units. How is the root mean square speed related to the temperature of a gas? m/s
What is the RMS speed of Helium atoms when the temperature of the Helium gas is 448 K? (Possibly useful constants: the atomic mass of Helium is 4.00 AMU, the Atomic Mass Unit is: 1 AMU = 1.66×10-27 kg, Boltzmann's constant is: kB = 1.38×10-23 J/K.) What would be the RMS speed, if the temperature of the Helium gas was doubled?
What is the RMS speed of Helium atoms when the temperature of the Helium gas is 412.0 K? (Possibly useful constants: the atomic mass of Helium is 4.00 AMU, the Atomic Mass Unit is: 1 AMU = 1.66×10-27 kg, Boltzmann's constant is: kB = 1.38×10-23 J/K.) What would be the RMS speed, if the temperature of the Helium gas was doubled?
**Please Show All The Steps** As I mentioned in the class assume that we have a GaAs (Gallium Arsenide) sample which was doped with excessive As to produce a resistivity of 0.05 Ωm. Owing to the presence of an unknown acceptor impurity the actual resistivity was 0.06Ωm, the sample remaining n-type. What were the concentrations of donors and acceptors present? (Please take μe=0.85 m2/Vs and assume that all impurity atoms are ionized) PHYSICAL CONSTANTS Avagadro's Number NA- 6.02 x 10*23...
