Plug in the values for initial and final temperature and pressure and the value for initial volume to find the new volume.

## Question on finding the volume of vapor and the volume of liquid

We don't save this data. Z is found in the charts in Figure 2-40 and Appendix A-13, using the quantities:. You can use 1.

Imagine trapping all of the water vapor in a box that's free to expand or contract whenever it needs to. Physics Stack Exchange works best with JavaScript enabled.

Find the Vapour Pressure (Clausius-Clapeyron Equation)

Of the three states of matter, gases undergo the greatest volume changes with changing temperature and pressure conditions, but liquids also undergo changes. Since this is a saturated state: How to calculate the volume of water in a certain amount of air, given the relative humidity? Hot Network Questions. These forces depend on the strength of the bonds holding molecules together and binding molecules to each other, and are different for every liquid.

Rearranging this equation to isolate volume, you get: How to Convert Vapor Pressure to Concentration. Yeah we didn't talk at all about vapor pressure and the only thing that it says in my book is that we can ignore vapor pressure if we keep the tempature low. All Rights Reserved.
