Consider the enthalpy departure function for the following: $(1)$ water at $180C$ and $1$ bar, $(2)$ water at $240C$ and $\frac{1}{b}ar,$ and $(3)$ water at $180C$ and $10$ bar. Rank them from the smallest magnitude to the largest. $($Hint: No calculations are necessary.$)$ Explain your answer.

$($a$)1,2,3$

Increase in temperature and pressure

b$.2,1,3$ will increase the enthalpy. At $100C$ and lbar, it has the locest.

c$.3,2,1$

d$.$ The departure is the same for $1,2,$ and $3.$
