1. Some incandescent light bulbs are filled with argon gas. What is the rms velocity Vrms for argon atoms near the filament, assuming their temperature is 2400 K? The Boltzmann's constant -3 k= 1.38 x 10 −2³ J/K. The molar weight of argon is 39.95 × 10-³ kg/mol. Number of molecules per mole is 6.023 x 10²3. Vrms = m/s

1. In the figure below, the probability of distribution of the velocities for a gas at two temperatures is given. T₁ T₂ velocity v (m/s) Probability From the graph, deduce if O A. T₁ > T₂ OB. T₁ <T₂ O C. T₁ = T₂ D. More information needed
