When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ÎH). Examples of Endothermic and Exothermic Processes. Photosynthesis is an example of an endothermic chemical reaction.
Hypothermia is a medical condition that is characterized by an abnormally low body temperature. It has three phases: mild, moderate, and severe. Mild hypothermia is classified as a body temperature of 90 - 99Â°F (or 32 - 35Â°C), moderate hypothermia at 82 - 90Â°F (28 - 32Â°C), and severe hypothermia is any temperature less than 82Â°F (28Â°C).
