Introduction
The objective of this lab is to find the amount of heat produced when you burn various items of food. The heat produced is recorded using a temperature probe recording the temperature of water heated by the food. We found that the best way to set up the apparatus is to put a clamp above a "ring clamp" on a ring stand. Put the temperature probe on the clamp and hang a soda can filled with 50mL of water from it's top by a glass stirring rod. Use a paper clip to position the nut underneath the can and hold a match up to it until it catches. Completely combust the nut and record the highest temperature the water reached.
Questions
1. Which nut seemed to be the biggestt and densest>
2. Which nut produced the greatest amount of heat?
3. Is there a relationship between how heavy a nut was and how much heat was produced?
4. If the Hazel nut sample was cut in half before it was burned, how would you expect the energy to differ?
