The r.m.s speed of oxygen is at a particular temperature. If the temperature is doubled and oxygen molecules dissociate into oxygen atoms, the r.m.s speed becomes
Important Questions on Kinetic Theory of Gases and Radiations
R.M.S. velocity of oxygen molecules at N.T.P is . The R.M.S velocity for the hydrogen molecule at N.T.P is
Uranium has two isotopes of masses units. If both of them are present in Uranium hexafluoride gas, find the percentage ratio of difference in rms velocities of two isotopes to the rms velocity of heavier isotope.
Temperature of an ideal gas, initially at $27^{\circ} \mathrm{C}$ is raised by $6^{\circ} \mathrm{C}$. The RMS velocity of the gas molecules will
The RMS velocity of a gas at $T^{\circ} \mathrm{C}$ is double the value at $27^{\circ} \mathrm{C}$. The temperature $\mathrm{T}$ of the gas in ${ }^{\circ} \mathrm{C}$ is (assume that the pressure remains constant)
To what temperature should hydrogen at $327^{\circ} \mathrm{C}$ be cooled at constant pressure so that root mean square velocity of its molecule becomes half of its previous value?
The mean free path of molecules of a gas (radius r) is inversely proportional to
The speed of molecules are given by $2 \mathrm{m} / \mathrm{s}$, $3 \mathrm{m} / \mathrm{s}, 4 \mathrm{m} / \mathrm{s}, 5 \mathrm{m} / \mathrm{s}$ and $6 \mathrm{m} / \mathrm{s} .$ The mean square speed is
The speed of four gases molecules are $1 \mathrm{km} / \mathrm{s},$ $3 \mathrm{km} / \mathrm{s}, 5 \mathrm{km} / \mathrm{s}$ and $7 \mathrm{km} / \mathrm{s}$ respectively. The difference between the R.M.S. speed and average speed is
