This physics video tutorial explains how to calculate the molar heat capacity of a monoatomic gas and a diatomic gas. it gives a simple formula to achieve this. In addition, it discusses the equipartition of energy principle as it relates to the average translational kinetic energy for each degree of freedom for a molecule. This video contains plenty of examples and practice problems.

who the hell put physics in my chemistry

Useful for physical chemistry also not just physics

You need to increase this interval of audible frequencies in your videos to make them more clear [200-600] Hz

In the last example, it seems to me that you calculated not translational KE (as the question required) but total KE - which includes (1) translational KE, and (2) rotational KE.

isn't this specific heat instead of heat capacity

how does N2 have 5 degrees of freedom? i thought the number of degrees of freedom was 3 times the number the atoms, which for N2 would be 2 atoms, so the DOF would be 6???

If you compare the molar heat capacity of Cl2, I2 and H2, at ambient temperature, apparently I2 has the highest, but since they are all 3 diatomic molecules with a degree of freedom of 5(at ambient temperature) I don't understand why their molar heat capacity is different. Can someone explain to me why?
