energy versus temperature graph the slope should be negative. The inconsistency of the data where catastrophic. Everything that was calculated using the slope such as the entropy were also incorrect. When the entropy change when compared to the enthalpy both have the same result negative. This would indicate the reaction to be spontaneous only at the lower temperatures. This is wrong because it should be spontaneous at all temperatures. This then affected the calculations of Gibbs free energy leading

Experiment B2‚ Heats of Combustion – The Bomb Calorimeter. Objectives: To calibrate a bomb calorimeter by the combustion of benzoic acid. Then to use the calibrated calorimeter to measure the heat of combustion of naphthalene and calculate the heat of formation of naphthalene.

Charles Darwin; the creator and innovator of the theory of evolution deemed the application of human skills of creating of fire the second powerful accomplishment of humankind (Falk‚2012). During the Ice Age‚ Hominidae first learned of natural fires caused by lightnings and used it to their advantage. Our ancestors capability to start a fire help them survived in the extreme weather during the Ice Age (Ancient History‚2010). The Earth’s temperature during the Ice Age was about -11.1 degrees Celsius
