Usually, f is written to represent the degree of freedom. ... Therefore, the degree of freedom of diatomic gas = 3+ 2 = 5. At a very high temperature (around 5000K), the vibrational … WebFor a diatomic gas, often 5 degrees of freedom are assumed to contribute at room temperature since each molecule has 3 translational and 2 rotational degrees of freedom, and the single vibrational degree of freedom is often not included since vibrations are often not thermally active except at high temperatures, as predicted by quantum ...

WebThis means that for a gas each degree of freedom contributes ½ RT to the internal energy on a molar basis (R is the ideal gas constant) An atom of a monoatomic gas can move in three independent directions so the gas has three degrees of freedom due to its translational motion. Therefore its internal energy, U, follows the equation U = 3/2 RT. http://physics.bu.edu/~redner/211-sp06/class-macro-micro/kinetic_equipartition.html
