At the top of the mountain the thermometer reads

0^{\circ} \mathrm{C}

and the barometer reads

710 \mathrm{~mm}

\mathrm{Hg}

. At the bottom of the mountain the temperature is

30^{\circ} \mathrm{C}

and pressure is

760 \mathrm{~mm}

\mathrm{Hg}

. Density of air at the top with that at the bottom is

View answer and explanation

Correct option: B

1.04: 1

The correct answer is B (1.04: 1) because the density of a gas is directly proportional to pressure and inversely proportional to temperature, allowing for a direct comparison between the top and bottom of the mountain.

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
