Energy > Energy in chemical reactions > Energy in chemical processes
During chemical processes substances break or form bonds to create other substances. During these processes energy is either absorbed or emitted. Chemical processes are classified as endothermic or exothermic depending on whether they emit or absorb energy.
Connection to Big Idea about forces: The electromagnetic force is responsible for all chemical processes. When chemical processes occur, energy is either absorbed or released.
Connection to Big Idea about particles: Atoms participating in chemical processes can absorb or release energy. Chemical reactions in nature occur in order for atoms and molecules to achieve the lowest possible potential energy stored in their bonds.
Connection to Big Idea about the cell: Cells use chemical reactions in order to produce the energy necessary for the different process they need to perform and ultimately for their survival.
