A certain gas possessess 3 degree of freedom corresponding to the translational motion and 2 degrees of freedom corresponding to rotational motion. (i) What is the kinetic energy of translational motion of one such molecule of gas at 300 K ? (ii) If the temperature is raised by `1^(@)C`, what energy must be supplied to the one molecule of the gas. Given Avogadro's number N = `6.023 xx 10^(23) mol^(-1)` and Boltzmann'a constant `k_(B)=1.38xx10^(-23)J molecule ^(-1)K^(-1)`.

Answer

`(i) 6.21 xx 10^(-21) J (ii) 20.78 J`
