Consider a nickel wall separating hydrogen gas that is maintained on one side at 5 atm and on the opposite at 3 atm. If the temperature is constant at 85°C, determine (a) the mass densities of hydrogen gas in the nickel wall on both sides and (b) the mass densities of hydrogen outside the nickel wall on both sides.

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?
