Lesson 7: Variation of Solution Properties with Temperature


In previous lessons, we considered thermodynamic properties such as the deliquescence, water uptake, and gas/particle partitioning of particles at a fixed temperature of 298.15 K. In Lessons 7 to 9 we examine how these properties depend on temperature.


Before starting, ensure that this browser window occupies only the left half of your screen. You should leave enough space for another browser window where you can enter data into E-AIM and read the results. If your screen is too small for two windows, print out this tutorial and use this window to run the E-AIM model. In these lessons we assume that you will have two browser windows open.

Select this link to open a second browser window containing the data input page for "variable temperature" calculations using Model II (http://www.aim.env.uea.ac.uk/aim/model2/mod2t.php). Arrange the windows on your screen so that both are visible and the left window contains this text.

The Lesson

This consists of the two sets of calculations described in the links below, which should be done in the order listed.

   a.  Aqueous ammonium nitrate and sulphate at a fixed relative humidity
   b.  Aqueous sulphuric acid at fixed relative humidity


You have completed Lesson 7, and learned that:

Now proceed to Lesson 8 to explore how solid/aqueous phase transitions (deliquescence) vary with temperature.
