At 400 K, the root mean square (rms) speed of a gas (molecular weight = 40) is equal to the most probable speed of gas . The molecular weight of the gas Y is
View answer and explanation
Correct option: B
4
Option B (4) is correct because equating the RMS speed of gas X to the most probable speed of gas Y and solving for the molecular weight of Y yields 4.

A quantity of hydrogen gas occupies a volume of at a certain temperature and pressure. What volume would half this mass of hydrogen occupy at triple the absolute temperature and the pressure were one-ninth that of the original gas?
In deriving the kinetic equation we make use of the root mean square speed of the molecules which is:
Consider the following statements for kinetic molecular theory of gases
a. Particles of a gas move in all possible directions in straight lines.
b. At any particular time, different particles in the gas have different kinetic energies.
c. Collisions of gas molecules are perfectly inelastic in nature.
The correct statement(s) is/are The compressibility factor of an ideal gas is The relative strength of interionic/intermolecular forces in decreasing order is Compressibility factor of an ideal gas is
