Rick Hess was diagnosed with diabetes in his early 40s. When he was in medical school‚ he participated in a study that analyzed insulin. His results were low and a little out of the normal levels. However‚ if he would have known more about the results like they do now‚ it would have predicted he would have become diabetic. In addition to being a diabetic‚ Rick has also had to overcome cerebrovascular disease in his 70s. Rick Hess is now 76 years old. He attended the West Virginia University to

Measuring the Enthalpy change of combustion Abstract This simple experiment is carried out to show the difference in the enthalpy change of combustion between two fuels‚ hexane and methanol. These fuels are individually weighed before and after used as heat source to heat water in a calorimeter. The result is used to find out amount of heat transferred by the fuel‚ amount of fuel used and the enthalpy change of combustion. Introduction Enthalpy change of combustion is the enthalpy change when

primary objective of this lab is to be able to determine the specific heat of a reaction by using a calorimeter. A calorimeter is a device used to determine the specific heat of chemical reaction or a physical change. The specific heat a reactions is used to refer to the amount of heat that is lost or gained when one gram of a particular substance increases or decreases by one degree Celsius. When a chemical reaction occurs in an open container most of the energy gained or lost is in the form of
