experiment is to determine how much energy is stored in high caloric food such as corn biofuel in this case. In this particular experiment the surface area of the container is used as the independent variable, 5 different sizes were used. The dependent variable of this experiment was the change in the temperature of water that is used to determine the amount of energy stored. The control variable is the time the biofuel burns, this time was set to 2:30 minutes by each container. It is hypothesised that if the container in which the corn oil is on has a greater surface area, then it will burn more calories at a set rate. The temperature in the water should be greater each time the surface area as the container increases in size. Important Safety Measures

ROBERT VAN DEN ABEELE High Calorie-Content Food Lab Report It is important to be contient that when setting up the experiment the corn oil will only ignite after it is heated to about 140 degrees Celsius approximately, it is also very important to be precautious when selecting the flask that is going to be used, it must be able to be heated without breaking. Materials *Thermometer * 250mL Erlenmeyer flask * Corn oil * Bunsen burner * 2 Stand * 5 evaporating dishes * 2 Wire Gauze *Water *Stopwatch *Lighter *Graduated Cylinder * Clamp Procedure 1)Pour 100 mL water into the 250 mL Flask 2)Set stand with wire gauze 3)Place Thermometer into beaker with water and place it on top of the stand

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
