|---|---|---|---|---|---|
| endothermic | a chemical reaction or process in which a greater amount of energy is required to break the existing bonds in the reactants than is released when new bonds form in the product of molecules
🗑
|
||||
| exothermic | a chemical reaction or process in which more energy is released than required to break bonds in the intial reactants
🗑
|
||||
| law of conservation of energy | states than in any chemical reaction or physical process energy may change from one form to another but its neither destroyed or created
🗑
|
||||
| heat | a form of energy that flows from a warmer object to a coller object
