Question

A diatomic gas of molecular mass $40$ g/mol is filled in a rigid container Find the K.E ?

Answer 1

A diatomic gas of molecular mass 40 g/mol is filled in a rigid container.

If molecules are moving with velocity v, then its kinetic energy is,

$\frac{1}{2}m{v}^2=n{C}_V\Delta T$

$=\frac{m}{M_o}{C}_V\Delta T$
