Slide Information 00:09 - Introduction 01:02 - Announcements 02:11 - where are we (chapter and timeline)? 04:00 - 1st Law: Energy is conserved for an isolated system ΔU = 0. 05:32 - Coin Experiment 06:35 - experiment: conclusion (the most important one so far) 06:51 - Boltzmann postulated that this parameter 07:11 - We can readily apply this equation to this expansion of gas. 08:11 - Now, what is the probability that... 09:05 - Problem: Gas A and Gas B are located in two halves of a container 13:07 - What if instead of the change in entropy... 13:33 - Formula (S =) 14:09 - Calculate the standard molar entropy of neon gas at (a) 200K, (b) 298.15K. 15:53 - Sadi Carnot 17:54 - match the scientist with his country 18:44 - entropy 19:28 - the Carnot Cycle 21:00 - A heat engine extracts work from a temperature gradient 21:41 - The Carnot Cycle (graph) 23:31 - what do we know for sure? (graph continued from Carnot Cycle) 24:18 - how efficient is a heat engine? 25:10 - efficiency (slide at 24:18 continued) 26:24 - how efficient is a Carnot Cycle? 27:28 - let's prove this: 27:52 - now, this pair of (T,V) data points lie on an adiabat: 29:55 - Problem: A heat pump is used to maintain the temperature of a building at 18°C... 32:03 - Problem: What is the entropy change, ΔS, for each of the four steps as a reversible Carnot cycle 32:31 - Diagram: Since S is a state function, we can write: 33:50 - so we represented in a Temperature-Entropy diagram... 34:48 - Since S is a state function, we can write:
In Chemistry 131C, students will study how to calculate macroscopic chemical properties of systems. This course will build on the microscopic understanding (Chemical Physics) to reinforce and expand your understanding of the basic thermo-chemistry concepts from General Chemistry (Physical Chemistry.) We then go on to study how chemical reaction rates are measured and calculated from molecular properties. Topics covered include: Energy, entropy, and the thermodynamic potentials; Chemical equilibrium; and Chemical kinetics.
