The explanation for cooling effect of ethanol on rubbing against skin has to be given. Concept Introduction: Heat is flow of thermal energy involving two bodies at various temperatures. The flow of thermal energy involving two bodies at various temperatures is called as heat. The flow of heat implies that energy is either released or absorbed on describing about energy changes that takes place during a process. Exothermic process is the chemical process in which heat is released to the surroundings. Endothermic process is the chemical process in which heat is absorbed from the surroundings. The change in enthalpy that is associated with the formation of one mole of a substance from its related elements being in standard state is called standard enthalpy of formation ( ΔH f ° ). The standard enthalpy of formation is used to determine the standard enthalpies of compound and element. The standard enthalpy of reaction is the enthalpy of reaction that takes place under standard conditions.
