substance and plot a G$-$T diagram for all phases at $1$atm.

$(20$pts$)$ Vapor pressure of water is given by $lnP=A-\frac{4880}{T}.$ The heat of

vaporization of water at $100C$ is $538ca\frac{l}{g}.$ Please calculate the volume of $1g$ of

water vapor at $1$atm and $100C.$

$(10pts)$ The vapor pressure of solid $C{O}_2$ below the triple point $(-56\mathrm{.}2C)$ is given
