Question

According to equipartition law of energy each particle in a system of particles have thermal energy E equal to.

• A. $E=k_{B}T$
• B. $E=\frac{1}{2}{k}_{B}T$
• C. $E=3k_{B}T$
• D. $E=\frac{3}{2}{k}_{B}T$

Answer 1

The correct option is D $E=\frac{3}{2}{k}_{B}T$

According to equipartition of energy, each particle have thermal energy $E$ equal to,

$E=\frac{f}{2}KT$ $[f=\text{degrees of freedom}]$

Here, $f=3$

$\therefore E=\frac{3}{2}KT$

Option $D$ is correct answer.
