360230 At what temperature is the root mean square speed of an atom in an argon gas cylinder equal to the rms speed of a helium gas atom at \( - 20^\circ C\) ? (Atomic mass of \(Ar = 39.9\,\,u\,\,of{\text{ }}He = 4.0\,\,u)\)

1 \(3.52 \times {10^3}\,\,K\)
2 \(2.52 \times {10^2}\,\,K\)
3 \(2.52 \times {10^4}\,\,K\)
4 \(4.52 \times {10^5}\,\,K\)

360231 Root mean square velocity of a particle is \(V\) at pressure \(P\). If pressure is increased two times, then the rms velocity becomes

1 \(2\;V\)
2 \(3\;V\)
3 \(0.5\;V\)
4 \(V\)

360232 The root mean square speed of gas molecules

1 Is the same for all gases at the same temperature
2 Depends on the mass of the gas molecule and its temperature
3 Is independent of the density and presure of the gas
4 Depends only on the temperature and volume of the gas
PHXI13:KINETIC THEORY

360233 When temperature of an ideal gas is increased from \(27^\circ C\) to \(227^\circ C,\) its \(rms\) speed is changed from \(400\;m{s^{ - 1}}\) to \(v_{s}\). Then \(v_{s}\) is

1 \(516\;m{s^{ - 1}}\)
2 \(450\;m{s^{ - 1}}\)
3 \(310\;m{s^{ - 1}}\)
4 \(746\;m{s^{ - 1}}\)
