With the aid of a labelled diagram, describe an experiment to investigate the conversion of the chemical energy in food into heat energy - Junior Cycle Science - Question a - 2017

Take a small piece of food (like a nut or piece of dried fruit) and secure it to a suitable holder, such as a skewer. Position the food directly above the flame of a burning candle or spirit lamp. Ignite the food so that it burns and releases energy as heat.

Observe the water's temperature before and after burning the food. Record the initial and final temperature of the water. You should note an increase in temperature, indicating the conversion of chemical energy into heat energy, which is absorbed by the water.

Draw a diagram showing the setup with the container of water, thermometer, food being burned, and the flame source. Label at least one component clearly, such as 'thermometer' and 'food being combusted', to ensure the diagram illustrates the experiment effectively.
