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

Kinetic Theory

Solution:

'$Nm$’ represents mass of gas in volume $V$, as $N$ represent number of molecules and $m$ represents mass of a molecule.
