# What physical changes occur to water as it vaporizes?

Jun 1, 2018

Does it not go from a condensed phase to a gaseous phase?

#### Explanation:

The which we can represent by the equilibrium..

${H}_{2} O \left(l\right) r i g h t \le f t h a r p \infty n s {H}_{2} O \left(g\right)$

Note that at ALL temperatures both WATER and ICE express a vapour pressure, the which for water we call it the
$\text{saturated vapour pressure}$, a function of temperature. ${P}_{\text{SVP}} \equiv 23.8 \cdot m m \cdot H g$ at $298 \cdot K$. What is ${P}_{\text{SVP}}$ at $373.15 \cdot K$?

And of course as water vaporizes it expresses a much GREATER volume.
