    has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20.25cm) as compared to HCl which has a greater molecular weight (36.4611g/mole) and diffused with dave=16.38 cm. A white ring of smoke formed closer to the heavier substance. The agar-water gel set-up used a petri-dish of agar-water gel with three wells on it. A drop of potassium permanganate (KMnO4) was put on one well‚ a drop of potassium dichromate (K2Cr2O7) was put on the other and a drop of methylene blue was put

    There is a positive correlation between the height at which the tennis ball was dropped and the amount of energy that it held. This energy was measured through the amount of gravitational potential energy that the tennis ball had before it was dropped‚ and by the amount of work it had done when displacing the sand. As shown in Table 2‚ when the tennis ball was dropped at a height of 1 meter‚ it only possessed a potential energy of 0.569 J. When dropped from 5.5 meters‚ it held a potential energy
