Liquid water at $140$C and $1,002\mathrm{.}7$ kPa has an internal energy $($on an arbitrary scale$)$ of $719$ kJ$/$kg and a specific gravity of $1\mathrm{.}122$ cm$3$ g$-1.$

$($a$)$ What is the enthalpy of water?

$($b$)$The water is brought to vapor state at $201$C and $1,500$ kPa, where its internal energy is $2,484\mathrm{.}4$ kJ$/$kg and its specific gravity is $135\mathrm{.}7$ cm$-3$g$-1.$ Calculate

$\backslash$Delta U and $\backslash$Delta H for the process.
