Consider a gas of triatomic molecules. The molecules are assumed to be triangular, composed of massless rigid rods with atoms at the vertices. The internal energy of a mole of the gas at temperature \(T\) is:
| 1. | \( 3 R T \) | 2. | \(\dfrac{5}{2} R T \) |
| 3. | \( \dfrac{9}{2} R T \) | 4. | \( \dfrac{3}{2} R T \) |
