Demonstrate an understanding of the term enthalpy change,. Δ. H. Construct simple enthalpy level diagrams showing the enthalpy change. Ectotherms. Rely mainly on external energy sources.. Endotherms. - Rely heavily on metabolic energy. Homeotherms. . maintain a relatively constant internal environment.. Poikilotherms. (= . heterotherms. INTRODUCTION. All reactions require energy to break bonds in the reactants, and all reactions give off energy when new bonds form to make products. The difference in energy required to break the bonds and to make the new bonds can tell you whether the reaction is endothermic or exothermic. . Do now activity: . State what ‘conservation of mass’ means. GOOD PROGRESS:. Define the terms endothermic and exothermic. Give some examples of endothermic and exothermic reactions. OUTSTANDING PROGRESS:. Boiling water.
