Determine the energy in a food

The energy in food can be determined by measuring how much heat energy is released when the food is burned.

The food you choose should be easy to burn, such as peanut seeds, walnut seeds, etc.

For every 1 ml of water to rise by 1°C, it needs to absorb 4.2 joules of heat energy.
