# What are the values of DeltaH and DeltaS for the change from gaseous to liquid H_2O?

Aug 16, 2017

#### Answer:

For the process... ${H}_{2} O \left(g\right) \rightarrow {H}_{2} O \left(l\right) + \Delta$

#### Explanation:

AS written, $\Delta H$ should be negative (i.e. heat should be a product of the reaction), and ALSO $\Delta {S}^{\circ}$ should be NEGATIVE, because we go from a gaseous phase to a condensed phase, which minimizes the probability of disorder.

As to actual values for the processes, you will find these in your text.
