CHEM 480 1nd Edition Lecture 3 Outline of Last Lecture I. EnergyII. States of MatterIII. Kinetic Molecular TheoryIV. Thermal EnergyV. Boltzmann DistributionOutline of Current Lecture I. System vs. SurroundingsII. WorkIII. Transfer of EnergyCurrent LectureI. System vs. Surroundingsa. The system is the sample of interestb. The surroundings are everything elsec. Types of systemsi. Open system: can exchange energy and/or matter with surroundingsii. Isolated system: can exchange neither matter nor energy with the surroundingsiii. Closed system: can exchange energy with surroundings but not matter 1. Combustion reaction: exothermic, system has less energy after2. Work done by the system is negative (w < 0)3. Heat is released by the system (q < 0)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.4.II. Transfer of Energya.b. E = q + W i. Work done by system (w < 0)ii. Work done on system (w > 0)c. Vocabi. Endergonic: E into systemii. Exergonic: E out of systemiii. Endothermic: q into systemiv. Exothermic: q out of systemIII. Worka. Work is the transfer of energy resulting in uniform motion in the surroundingsb. One type of worki. Gravitational attraction of earth on mass: w = mghc. Expansion worki. w = − Pext ΔVii. Free expansion: Pext = 0 (w = 0)d. Maximum worki. The opposite of free expansion (where w = 0)ii. Pext = tiny bit smaller than
