Curated OER
Quasistatic and Reversible Processes
The theories behind Quasistatic and Reversible Processes are offered in this chemistry video. Sal sets up a hypothetical situation in which gases are escaping from a piston in a car's engine. He uses this scenario to illustrate exactly...
Curated OER
pKa and pKb Relationship
Sal illustrates the all-important relationships between pKa and pKb in this chemistry video. This relationship is what determines whether an acid is considered to be "weak," or "strong." The mathematics behind figuring out these...
Curated OER
Thermodynamic Entropy Definition Clarification
In the previous video, Sal introduced students to entropy and the 2nd Law of Thermodynamics. An example he used had a couple of points that were factual, but not clear to many students. In this video, he goes over those points again in...
Curated OER
Titration Roundup
Titration curves are the focus of this chemistry video. Students see that if a weak base is titrated with a strong acid, then the pH equals the pKb at the half-equivalence point. The base will have an equilibrium, but the acid will not...
Curated OER
Vapor Pressue
A problem from a chemistry textbook is posed on the screen. Sal solves the problem which attempts to calculate vapor pressure using the Ideal Gas Law. The rate of evaporation of water given a certain volume, temperature, and pressure is...
Curated OER
Mini-Video on Ion Size
Sal discusses what happens to elements when they become ionized. He demonstrates that when neutral atoms become ionized, it can significantly change their relative atomic sizes. He uses the Periodic Table of the Elements to illustrate...
Curated OER
Work from Expansion
Sal's series on the Law of Thermodynamics continues with this video on how heat and work are added to, or taken away from, a system. As a result of the heat and work energy, the system that is being worked on will transform into another...
Curated OER
Redox Reactions
In previous videos, Sal talks about oxidation vs. reduction when acids and bases are reacting together. In this presentation, he goes into the "nitty-gritty" of exactly how and why electrons "choose" to leave one compound and "join" with...
Curated OER
States of Matter Follow-Up
Sal continues his explanation of the states of matter by focusing on hydrogen bonds. This time, he uses plasma as the substance being studied, and explains how the hydrogen bonds change as the substance goes from solid, to liquid, to gas.
Curated OER
More on Oxidation States
In the previous video, Sal presented how elements move toward a state of oxidation (by losing electrons), and a state of reduction (by gaining electrons). This lecture takes that concept a bit further, and he provides more examples.
Curated OER
Enthalpy
Sal introduces students to the term, "enthalpy" in this chemistry video. He defines enthalpy as: the internal energy, plus the pressure times the volume found in a system. He constructs a PV diagram to illustrate this point.
Curated OER
More Exponential Decay Examples
This video is an extension of the previous video, which introduced exponential decay, and showed students how to solve for it. More examples are given to give students further practice.
Curated OER
Hydrogen Peroxide Correction
This very short video is used to correct an error that Sal made in the previous video regarding the solution, Hydrogen Peroxide.

Bailout 5: Paying off the debt
Chronicling the "first wave" of the financial crisis with a short review, Sal goes on to explain how bad choices and unfortunate moves by several banks can lead to total disruption of a financial system. Sprinkling real-world examples...
Curated OER
Bailout 12: Lone Star Transaction
Departing from his trademark theoretical balance sheets, Sal guides the viewer through a real-life "outlandish" transaction between Merrill Lynch and Lone Star Funds. Budding economists can exercise their growing economic skills by...
Curated OER
Bailout 15: More on the solution
Sal continues his argument for "the Plutzy Plan" (named after his friend who initially poses the idea). He outlines both theoretical and practical implementation ideas to restore the financial system. His theories will invigorate your...
Curated OER
Bailout 11: Why these CDOs could be worth nothing
Differentiating between a $700 billion "blank check" and the acquisition of assets, this video explores the idea that the CDOs purchased by the government could be worth nothing. Sal takes students through the mathematical and economic...
Curated OER
Bailout 4: Mark-to-model vs. mark-to-market
The saga of Sal's fictional bank - as it relates to the very real-world banking world today - continues in this video, which covers ways to account for an asset (mark-to-model vs. mark-to market). Sal does not hide his opinion here,...
Curated OER
Bailout 2: Book Value
Your class has been exposed to the effects and ramifications of the recent financial crisis. In this video, Sal helps to clarify the terms and procedures of what has been happening. He uses a fictional balance sheet to illustrate the...
Curated OER
Bailout 1: Liquidity vs. Solvency
Introducing the circumstance surrounding the 2008 bailout and financial crisis, Sal uses a simplified analogy to help students to see the heart of the matter. He covers the importance of credit and credit scores, as well as what happens...
Curated OER
Bailout 7: Bank goes into bankruptcy
Some banks escaped certain disaster with a bailout by the government. But, what about the rest? Sal explains the intricacies and dynamics of a bailout down to the details on a balance sheet. He also provides a thorough definition of...
Curated OER
Bailout 8: Systemic Risk
Using several balance sheets, Sal illustrates the connectivity of banks and how one bank failure can affect many. Again, he uses the example of Lehman Brothers as the "catalyst for this chain of events" to explain how one bankrupt bank...
Curated OER
Bailout 14: Possible Solution
Ripe for discussion in your economics and government classes, this video features Sal's idea for a best possible solution to the financial crisis. He first details the situation and what the plan would entail; he then takes viewers...

Bailout 6: Getting an equity infusion
What does a bank do when it has reached the end of its equity? Sal demonstrates the eleventh hour attempts by banks to liquidate all assets before doomsday. He also covers some of the rationale behind not accepting market prices and...
