My Aim

"My aim is to find out how much energy is released when burning different types of crisps and to find which one releases the most energy."

Walkers

Hula Hoops

French fries

Peak Potatoes

34 g/100g of fat = 2200kJ/100g of

energy

28.1g/100g of fat = 2106kJ/100g of energy

17g/100g fat= 1800kJ/100g

2.5g/100g of fat., 1456kJ/100g

The Preliminary Experiment

The preliminary experiment we had to record the amount of energy released.

I had to burn two different types of pasta and then put it under a test tube of 25cm of water. I did this experiment for practice before I did the crisp experiment. We also collected variables, fair testing points, and risk assessment from this experiment.

The variables that will affect the way the experiment works are:

* Amount of water -

* Amount of food - The more food the more energy will be released.

* Glass thickness - Effects how much heat gets to the water.

* Size of food - Size of food affects how much energy in crisp so need to be weighed
