Question

the translational kinetic energy of one mole of Oxygen gas at a temperature is 15*10(to power -20)J. Its rotational kinetic energy at same temperature is​

Answer 1

KE for one mole is

KE = 3RT/2

According to KTG it is consider that Ideal gas is point mass or very small particals so there Rotation energy is not taken in account, Only there Transverse KE is consider in all three dimensions .

Average KE associate with a particular direction is RT/2
