A mixture of two gases, helium (He) and neon (Ne), is at a constant temperature. The ratio of their root mean square speeds (vrms) is 2:1. If the molar mass of He is 4 g/mol, what is the molar mass of Ne in this mixture?

Root mean square speed of the molecules of ideal gas is $v$. If pressure is increased two times at constant temperature, the rms speed will become

At what temperature is the root mean square velocity of gaseous hydrogen molecules equal to that of oxygen molecules at ${47^ \circ }C$

At room temperature (27$^ \circ C)\;$ the rms speed of the molecules of a certain diatomic gas is found to be 1920 m${s^{ - 1}}$. The gas is

At 0 $K$ which of the following properties of a gas will be zero

Which factor does NOT affect the speed of gas molecules?

The value of densities of two diatomic gases at constant temperature and pressure are ${d_1}$ and ${d_2},$ then the ratio of speed of sound in these gases will be

How many times a diatomic gas should be expanded adiabatically so as to reduce the root mean square velocity to half

According to the kinetic theory of gases the $r.m.s$ velocity of gas molecules is directly proportional to

The root mean square speed of the molecules of a diatomic gas is $v.$ When the temperature is doubled, the molecules dissociate into two atoms. The new root mean square speed of the atom is

The kinetic energy, due to translation motion, of most of the molecules of an ideal gas at absolute temperature $T$ is
