In this lab‚ we will measure the heat of combustion‚ or calorimetry‚ of a candle and compare the found quantity with known values for other hydrocarbons. The calorific value is the total thermal energy released when a substance goes through complete combustion with oxygen. In order to achieve the purpose of this lab‚ we must first determine the mass of the tea candle. Then‚ we will determine our room temperature‚ measure about 100 mL of chilled water‚ and then pour the water into the given empty

Heat exhaustion and heatstroke As days slowly begin to heat up it is important to stay cool and keep hydrated across the screaming scorching sun. Summer time usually means longer days and if you live close to the equator you know about the 100+ degree weather that comes with it. Without the proper precautions you could easily fall to heat exhaustion or far worse a heat stroke. Athletes are more prone to this type of sudden illnesses because of the constant running and exercise they do on a daily

Research Summary Heat stroke is defined by Knochel and Ouchama (2002‚ p. 1978) as “a core body temperature that rises above 40°C (105°F) and that is accompanied by hot‚ dry skin and central nervous system abnormalities such as delirium‚ convulsions‚ or coma.” Heat stroke can be the result of either exposure to a high environmental temperature or from an elevated core temperature due to strenuous exercise. However‚ due to the presentation of an ‘unconscious unknown’ the diagnosis of heat stroke can be

Swine Heat Stress ABSTRACT The purpose of this research project is to identify the effects of heat stress on swine. Heat stress is physiological distress caused by excessive temperatures usually over 80-85 degrees Fahrenheit that can result in profoundly adverse effects in swine production. The first phase of this project involves the analysis of these harmful effects on sows‚ gilts‚ and boars. Multiple journal articles will be used to establish these effects. The final phase involves
