Below is a Temperature$-$vs$.-$Energy$-$Added graph for kryptonite, derived in the laboratory of Lex Luthor. Lex has four insulated containers, each containing a $1\mathrm{.}0$ kg sample of kryptonite. The sample in one of the containers $\backslash (($A$)\backslash )$ consists of $\backslash (50\backslash \%\backslash )$ solid and $\backslash (50\backslash \%\backslash )$ liquid, while the contents of the other three containers $\backslash (($B$,$ C$,$ D$)\backslash )$ are $\backslash (33\backslash \%\backslash )$ liquid and $\backslash (67\backslash \%\backslash )$ gas. Lex now combines the contents of all four containers into a single thermally$-$insulated container, and the whole $4\mathrm{.}0$ kg sample comes to equilibrium. Determine the final state of this sample, giving the temperature in terms of the melting and boiling points of kryptonite, was well as the percentages of each phase in the combined sample, if applicable.
