What is the ratio of the average kinetic energy of a SO2 molecule to that of an O2 molecule in a mixture of two gases? What is the ratio of the root mean square speeds, urms, of the two gases?
The previous exercise gives an expression for sound, the speed of sound in a gas. Determine the ratios sound/rms, sound/mostprob, and sound/. Which, if any, of these ratios is less than one? What are the physical interpretations of these ratios?
Given that 1.00 mol of neon and 1.00 mol of hydrogen chloride gas are in separate containers at the same temperature and pressure, calculate each of the following ratios. (a) volume Ne/volume HCI (b) density Ne/density HCI (c) average translational energy Ne/average translational energy HCI (d) number of Ne atoms/number of HCl molecules
Under what conditions of volume does a van der Waals gas behave like an ideal gas? Use the van der Waals equation of state to justify your answer.
If relativistic effects were ignored, what temperature is required for hydrogen atoms to have an rms-average speed of 3.00108m/s? What do you think is the potential for actually achieving this temperature?
Starting with the definition of rate of effusion and Graham’s finding relating rate and molar mass, show how to derive the Graham’s law equation, relating the relative rates of effusion for two gases to their molecular masses.
