Questions
A vessel contains a mixture of one mole of oxygen and two moles of nitrogen at 300K. the ratio of the average rotational kinetic energy per molecule to that per molecule is
detailed solution
Correct option is A
Kinetic energy per degree of freedom is 12KTAs diatomic gas posses two degree of freedom for rotational motion therefore rotational kinetic energy = 2.12KT=KTIn the problem both gases are diatomic and have same temperature. Therefore the average rotational kinetic energy will be equal to one.Similar Questions
