Thermochemistry and Calorimetry
| Why? | Chemical reactions release or store energy. If the energy is in the form of heat, the reactions produce changes in temperature. The amount of energy released or stored by a chemical reaction can be determined from the change in temperature. You need to know how much energy is released or stored by a reaction in order to evaluate the utility of that reaction or to identify the conditions essential for that reaction to occur efficiently and safely. |
| Learning Objectives |
• Understand the concept of energy and the Joule unit of
energy. • Quantify the relationship between the flow of heat and the change in temperature. |
| Success Criteria |
• Effectively use the relationship between the flow of
heat and a change in temperature. |
| New Concepts | energy, heat, Joule and kilojoule (J and kJ, rhymes with cool), heat capacity, specific heat capacity, calorimetry |
