With this in place we then get the oil in question [5 used in this experiment] we then very carefully release one drop of oil and begin timing it. It will then slide down the slide and once it hits the heat proof mat we then stop the stop watch, and record the time, after doing this for the first oil, we need to thorooughly wash and dry the slide and repeat it for the other 4 oils.
In order for me to obtain the most fair and unbiased results possible, not to mention the most accurate and factual, I have to make sure the test is performed unbiasedly and fair in every field.
I have to make sure in each of the 5 tests that I release exactly one droplet of oil in each case, as the more I let out the faster it will flow, so I must keep it even in all cases.
Timing must be dead accurate in each test to make sure I get the correct timings, as there may be some measurements a lot closer than others and they need to be intricately timed.
The slope must be angled the same each time as well, as the steeper the slope the faster it would slide down, so it must remain even to get a fair, realistic comparison
I predict that as the oils get thinner they will slide down the slide much faster that the thicker oils. Seeing as once the oils get too thick, the particles will struggle to separate from each other thus causing the “sliding” motion we see. With thinner liquids, the particles are more sparcely based also the force is much weaker between the molecules, they will now slide much more freely away from each other.
I feel there will be quite a large difference in the times, the thicker oils will take considerably longer than the thiner ones.
Examining my results, it is clear to see a straight pattern, as the oils get thicker [moving down the list] it takes longer for it to travel down the slide. This is due to the molecules struggling to separate from each other as they have stronger molecular bonds, this proves my prediction right. The molecules find it easier to untangle and go down the slide when they are thinner, thus proving a faster result.
The difference is subtle in the means of secs taken until the last 2 oils, liquid [araffin and Lubricating oil take considerably longer as they are the 2 thickest by far.
The boiling points rise as the oils get thicker, the thicker the oil, the prime example being the thickest, lubricating oil, this also has the highest boiling point.
Flammability increases as the oils get thinner, we conducted a test to see how flammable each oil was, placing a half dozen drops in a dish and lighting them with a splint to see how fast and in what way the oil lights.
