S-I:

\mathrm{CH}_4, \mathrm{CO}_2

has value of

\mathrm{Z}

(compressibility factor) less than one at

0^{\circ} \mathrm{C}

.

S-II:

\text{Z} < 1

is due to the attractive forces dominate among the molecules.

View answer and explanation

Correct option: A

Both statements are correct and statement-II is correct explanation of statement-I

Option D (S-I is incorrect and S-II is correct) is correct because

CH_4

and

CO_2

have Z > 1 at 0°C, and Z < 1 is indeed due to dominant attractive forces.

A quantity of hydrogen gas occupies a volume of

30 \mathrm{~mL}

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
