Key Ideas • Energy can move from one place, object, or system to another. • Substances heat or cool as a result of energy transfer. • Energy transfers from warmer matter to cooler matter until both reach the same temperature. Heat evolved by the reaction = Heat absorbed by the water + Heat absorbed by the bomb or, in equation form: qreaction= -(qwater + qbomb) (where qis the symbol for heat) The qreactionhas a negative value because the combustion reaction is exothermic(i.e., it releases energy to the surroundings). Heat is the energy an object has because of the movement of its atoms and molecules which are continuously jiggling and moving around, hitting each other and other objects. When we add energy to an object, its atoms and molecules move faster increasing its energy of motion or heat.
