Answer to Question #158035 in Molecular Physics | Thermodynamics for Max

Question

Explain rotational energy in term Of J.

Answer 1

In molecular physics and thermodynamics, one degree of freedom of rotational motion has energy $\frac{1}{2}kT$ . At room temperature $(298\ K)$

$\frac{1}{2}kT\approx\frac{1}{2}\cdot 1.38\cdot10^{-23}\cdot298=206\cdot10^{-23}\ (\ J\ )$ .Answer
