population inversion
It has to do with the inversion of the population. DUH!

well, i can answer 2 and maybe 3

homogeneous - Mixture that appears the same throughout
saturation - Containing the maximum amount of absorbed solute
inhomogenous - probably opposite of homogeneous which is a hetrogeneous ( mixture that does not appear the same throughout )

The difference between a homogenous and a hetrogeneous is the appearances ( im pretty sure... )
