Experiment 1 : Bonding in Liquids Purpose: To study the effect of intermolecular bonding in liquids. List of Materials used: - 1 stopwatch - 3 x 500 ml mason jars - 3 small spoons - 1 metric ruler - 1 marking pen - 300 ml of water - 300 ml of paint thinner (Varsol) - 300 ml of vegetable cooking oil Summary of Method: 1) Clear a space on the counter top or kitchen table. 2) Using a marking pen, measure and mark each jar at 1.0 cm spaces up the side of the jar. 3) Fill each jar about 2/3 full, up to one of the marks. Then, starting at the level of the liquid, label the mark 0, the next mark down 1, the next mark one down 2, and so on to the bottom of the jar. This will enable you to easily measure the depth of the conically shaped depression that forms when you stir the liquid inside the jar. This depression is called the vortex.

4) Stir the paint thinner vigorously ten times. Stop stirring and note two things, the depth of the vortex and the time it takes for the vortex to disappear. 5) Repeat enough times to obtain consistent results.
