Homework Help: Chemistry - Energy and Change rev (help+check)

Posted by Babelii on Wednesday, March 23, 2011 at 7:36am.

so i was revising for a test next week, and i had problems with the below designing question, so could someone please help me out.


54. The caloric content (energy content) of foods is measured using a bomb calorimeter. A sample of food is burned in oxygen, O2, inside the calorimeter. You can make a simple food calorimeter using an empty food can or pop can. Design an investigation in which you make your own calorimeter and then use your calorimeter to measure the energy content of a piece of cheese or a cracker. Include a diagram of your proposed calorimeter. List the data, and other observations, that you plan to record. Get your teacherís approval before carrying out your investigation. Note: Some students have a severe nut allergy. Do not use peanuts, or any other nuts, in your investigation

SO I DECIDED THAT USING ONE OF THE CANS, I WILL HEAT UP THE CHEESE FROM THE BUNSEN BURNER AND JUST RECORD THE TEMPERATURE CHANGE, JUST LIKE HOW YOU DO IT WITH THE COFFEE-CUP, BUT THIS TIME, YOU TAKE THE SPECIFIC HEAT CAPACITY OF THE TIN...AM I IN THE RIGHT DIRECTION?
