An FKD Feature exclusive. When our next president takes office in 2017, he or she will have a lot of preparatory work already underway. A Presidential transition team starts working as early as the primaries to ensure that the massive undertaking of transferring power to the next president goes smoothly.
Endothermic vs. Exothermic Reactions. An endothermic reaction occurs when energy is absorbed from the surroundings in the form of heat. Conversely, an exothermic reaction is one in which energy is released from the system into the surroundings. The terms are commonly used in the physical sciences and chemistry.
Work must be done in order to get these reactions to occur. 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 (+Î´H).
