The gas having average speed four times as that SO₂ (molecular mass 64) is
The temperature of a given mass is increased from 27°C to 327°C. The rms velocity of the molecules increases
The root mean square velocity of gas molecules is 10km/s. The gas is heated till its pressure becomes four times. The velocity of gas molecules will be
Assertion: The root mean square and most probable speeds of the molecules in a gas are the same. Reason: The Maxwell distribution for the speed of molecules in a gas is symmetrical.
A gas storage tank has a small leak. The pressure in the tank drop more quickly if the gas is hydrogen than if it is oxygen. Why?
Three vessels of equal capacity have gases at the same temperature and pressure. The first vessel contains neon (monoatomic), the second contains chlorine (diatomic), and the third contains uranium hexafluoride (polyatomic). Do the vessels contain equal number of respective molecules? Is the root mean square speed of molecules the same in the three cases? If not, in which case is v_rms the largest?
