Information

5 144 A greasy substance isolated from the fatty deposits around meat. Melts at 16 degrees centigrade, but has a high boiling point much above that of water.
6 172 Very similar in consistency to Sample 5. I found this to be a common component of many animal and vegetable fats. It melts at 31 degrees centigrade.
Instructions: Enter the number of grams you wish to burn in the top box of the sample. Click on the "Analyze" button at the bottom of the box. Watch the reaction and wait for the result to appear in the bottom box. Write this number down and repeat the experiment with a different number of grams until you have enough data for a graph.
