as part of my science fair project and the limited funding my advisor has, i have to make a calorimeter which is able to burn saw dust efficiently.
i was thinking something to the likes of nutritional calorimtry (where it has the test tube and heat source under it which is than burned to show how much calories it emitted.) but i wasn't sure if additive amount of substances (such as vegetable oil and sawdust) would still result in the same if i did a control experiment on the vegetable oil itslef.
anybody out there could answer my question if hess's law can be applied in my situtation? i know it probably won't burn completely, but am unsure about the subject in question
thanks in advance to the responder
