Unit 7: Thermodynamics
(Calorimetry & Heating Curves)
Key Learning Targets
Explain the difference between kinetic and potential energy Define heat and work and explain the sign of ‘q’ and ‘w’ with respect to the system. State and interpret the First Law of Thermodynamics. Interpret a potential energy diagram to determine energy change for a reaction and classify it as endothermic or exothermic. Describe the energy transfer between a system and its surrounding during a phase or temperature change as endothermic or exothermic. Calculate the quantity of energy transferred, mass of substance involved, or temperature change for a system that has undergone a temperature change. State the physical meaning of heat of fusion, heat of vaporization, and specific heat capacity. Identify phases present and the various phase change temperatures for substances from a heating/cooling curve. Recognize that energy can be stored in an object or system as thermal energy or phase energy. Calculate the quantity of energy transferred, mass of substance involved, or temperature change for a system that has undergone a phase change. |
