The root mean square speed of the molecules of diatomic gas is . When the temperature is doubled, the molecules dissociates into two atoms. The new speed of the atom is:
View answer and explanation
Correct option: C
Option C () is correct because when the temperature is doubled and the diatomic molecule dissociates, the new RMS speed becomes twice the original RMS speed.

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
