A human adult breathes in approximately

0.50 \mathrm{~dm}^3

of air at

1.00 \mathrm{~bar}

with each breath. If an air tank holds

100 \mathrm{~dm}^3

of air at

200 \mathrm{~bar},

how many breathes the tank will supply?

View answer and explanation

Correct option: A

40,000 \text{ breaths}

Option A (40,000 breaths) is correct because it is calculated using Boyle's law to find the total volume of air at 1 bar and then dividing by the volume per breath.

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
