The 'Nutty Flame' experiment is to find out which nut, of two different types of nuts, releases more energy when burnt. This can be achieved by burning each nut, and using the flame to heat up 10ml of water. Whichever nut increases the temperature of the water by a greater amount contains more energy than the other.
This experiment has three key variables, two of which must be kept constant. They are shown in the table below.
Variable
Constant/Varied?
Volume of water
Constant
Mass of nut
Constant
Type of nut
Varied
For this experiment, you need:
A scale of some sort (preferably accurate to the nearest gram)
A lighter
A pair of tweezers
A stopwatch
Two kinds of nuts (in this case, peanuts and cashew nuts.)
50ml of water
