Question

One mole of oxygen occupies a volume of $24 L$ at $20^{\circ} C$ and $1 a t m p r e s s s u r e$ . Find the total translational kinetic energy in kiloJoules(rounded off to nearest integer).

Solution

Translational kinetic energy of a gas with three degrees of freedom= $\frac{3}{2} n R T = \frac{3}{2} \times 1 \times R \times 293 \approx 3648 J$

We know that, for an ideal monoatomic gas, the total internal energy is a result of the translational kinetic energy only. For the oxygen molecule $O_{2}$ (assume it doesn't oscillate along the bond axis), which rotates as well as translates, choose the correct statement(s) from the following
