For a multicomponent mixture containing any number of species, prove that M ¯ i = M + ( ∂ M ___ ∂ x i ) T, P − ∑ k x k ( ∂ M ___ ∂ x k ) T, P where the summation is over all species. Show that for a binary mixture this result reduces to Eqs. (10.15) and (10.16).

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
