The development process of software simulating physical chemistry experiments “The determination of saturated vapor pressure of liquid” as an example was shown based on Flash 8 software as a software developing platform and Photoshop as auxiliary software. The process of elements and instruments’ formation, the connection of instruments, the production of all kinds of scenes and their animation, the recording of sound, the simulation procedures were displayed. The courseware has been used in the physical chemistry experiment teaching. The good effect is obtained from the statistics of the student evaluations.

We present a spreadsheet-assisted exercise using Microsoft Excel software for the<br>determination of the universal gas constant, R, in 35,712 different units. This large<br>number of units arises from a simple enumeration of possible pressure-volume unit<br>combinations and energy unit combinations covering SI (metric), Imperial (British), and<br>American units. In turn, various units for force and area used for defining pressure, and<br>various units for force and distance used for defining energy are explored. This<br>presentation serves as an excellent exercise for high school and undergraduate students to<br>master the skill of dimensional analysis, unit conversions, and basic combinatorics in<br>general chemistry and physical chemistry courses. Instructors can also use the described<br>exercise of constructing conversion matrices to train students in how to efficiently use the<br>Microsoft Excel spreadsheet program.
