Consider 1

c{m^3}

sample of air at absolute temperature

{T_0}

at sea-level and another

1\,\,c{m^3}

sample of air at a height where the pressure is one third atmosphere. The absolute temperature

T

of the sample at the height is :

View answer and explanation

Correct option: D

Cannot be determined in terms of

{T_0}

from the above data

Option D is correct because without knowing the mass of the air samples, we cannot determine the relationship between the temperatures using the ideal gas law.

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
