Asystem undergoes a two-step process. in step 1, it absorbs 50. j of heat at constant volume. in step 2, it releases 5j of heat at 1 atm. as it returned to its original internal energy. find the change in the volume of the system during the second step and identify it as an expansion or compression.

What is the typical rotational frequency frot for a molecule like n2 at room temperature (25∘c)? assume that d for this molecule is 1å=10−10m. take the total mass of an n2 molecule to be mn2=4.65×10−26kg. you will need to account for rotations around two axes (not just one) to find the correct frequency. express frot numerically in hertz, to three significant figures.
