Figure 1 Procedure for the experiment. 3-mL HCl was transferred to a 10-mL graduated cylinder. The graduated cylinder was carefully filled with water (by pouring it through the walls of the cylinder using a wash bottle). The cork stopper with paper clip and Mg ribbon was placed into the graduated cylinder. The hole of the cork was covered with a finger as the cylinder was turned upside down prior to its placement in a beaker of water. After all the of the Mg ribbon reacted, the position of the cylinder was adjusted to equal the levels of water inside and outside the cylinder. The volume of water and temperature near the cylinder opening was recorded.EXPERIMENT 6A: DETERMINATION OF THE MOLAR VOLUME OF A GAS AND THE UNIVERSAL GAS CONSTANT

Figure 2 The three trials of the experiment.

Figure 3 Settling of graduated cylinder into water. Bubbles originating from the Mg ribbon were formed upon the inversion of the graduated cylinder due to reaction of Mg ribbon with HCl. The gas continued to occupy more space as the reaction goes on. The system was allowed to stand until all of the Mg ribbon was consumed. Figure 4 Error. Soapy bubbles were formed and settled at the top of the inverted graduated cylinder during the reaction. This may be due to incomplete rinsing of the glassware during the cleaning.EXPERIMENT 6B: CHARLES LAW

Figure 1 Sealed capillary tube. One end of the tube was immersed in oil. The opposite end was sealed by melting it through an alcohol lamp.

Figure 2 Set-up. The capillary tube was tied with a thermometer. The thermometer was then immersed at different temperatures (at around 0, 20, 40, 60, 80, 100 degrees Celsius). The distance of the rise of oil inside the capillary tube was measured using a ruler.
