Theresa creates an experiment where she mixes two red-colored substances together in a container and observes the solution slowly changing from red to blue for the next eight minutes. the solution becomes completely blue after eight minutes. what does this represent about the type of change happening in the container? a chemical change started immediately and finished at eight minutes. a non-chemical change started immediately and finished at eight minutes. a chemical change occurred at four minutes. a non-chemical change occurred at four minutes

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
