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)

the mass of the gas present in the volume $V$

Answer 2

$PV =\frac{1}{3} NmV ^{-2}$ The man of the gas present in the volume $V$ $\frac{ P _{1} V _{1}}{ T _{1}}=\frac{ P -2 V _{2}}{ T _{2}}$ The kinetic theory $V$ is the volume in between mass and other pressure.
