Question

The kinetic theory of gases gives the formula $PV=\frac{1}{3}Nm{\bar{v}}^2$ for the pressure P exerted by a gas enclosed in a volume $V$. The term $Nm$ represents

• A. the mass of a mole of the gas
• B. the mass of the gas present in the volume $V$
• C. the average mass of one molecule of the gas
• D. the total number of molecules present in volume $V$

Answer 1

Answer: (B)

$<br/>PV=\frac{1}{3}Nm{V}^{-2}<br/>$
The man of the gas present in the volume $V$
$<br/>\frac{P_1{V}_1}{T_1}=\frac{P-2V_2}{T_2}<br/>$
The kinetic theory
$V$ is the volume in between mass and other pressure.
