Understanding the Heat Transfer Equation in Thermodynamics
This video explains the heat transfer equation, Q equals MC delta T, which helps us understand the math behind thermodynamics. It breaks down the meaning of each variable in the equation and provides an example of how to use it to...

The Laws of Thermodynamics, Entropy, and Gibbs Free Energy
We've all heard of the Laws of Thermodynamics, but what are they really? What the heck is entropy and what does it mean for the fate of the universe? How does soap work?! So many questions answered in this clip! Enjoy!
Professor Dave Explains
Le Chatelier's Principle
If a system is at equilibrium, and we do something to it, it will shift in a particular way. It is quite easy to predict the behavior of equilibria if we know about these three simple situations!

State of the system
It explains the state of the system by state functions or state variables and describes internal energy as a state function.

Heat and Temperature
We all know what it's like to feel hot or cold. But what is hot? What is cold? What does temperature really measure? Don't pretend like you haven't lost sleep over this. Well you don't have to fret any longer, Prof Dave will take you...
Professor Dave Explains
Internal Energy
We know about kinetic energy and potential energy, which can interchange when an object moves through a gravitational field, so let's add to that list the internal energy of the object. This gives us a new and comprehensive way to...

What Is NOT Random?
Twelve fundamental particles exist in our universe, and they interact in exactly four ways. Does this mean we should be able to predict the future? We know entropy increases, but how does that impact us? These questions and more become...

Carnot Cycle and Carnot Engine, Thermodynamics, Physics
The Carnot Cycle is the focus of this chemistry video. Carnot was a French engineer who proved that energy transfers happen in a cycle. They start and finish at the same pressure, volume, and temperature. A system that completes the...

Gibbs Free Energy Example, Thermodynamics, Chemistry
Sal continues his discussion of spontaneous reactions by setting up a reaction between two substances and using the Gibbs Free Energy method to determine its spontaneity. This video is challenging in terms of math, and it would be...

PV-Diagrams and Expansion Work, Thermodynamics, Physics
In this chemistry video, Sal explains why work from expansion in an energy transfer occupies the space underneath the curved line of a PV Diagram. Pressure is plotted on the left axis, and volume is represented on the horizontal axis of...

Efficiency of a Carnot Engine, Thermodynamics, Physics
In the world of chemistry, efficiency is defined as: the work a system does, divided by the energy given to that system to complete the work. Sal illustrates this important chemistry concept by drawing a PV graph that shows a Carnot...

Work Done by Isothermic Process, Thermodynamics, Physics
Since the temperature of a system is crucial in its energy transformation, Sal examines two processes that greatly affect temperature in a system: the Isothermal Process and the Adiabatic Process. He sets up an example and illustrates...

Quasistatic and Reversible Processes, Thermodynamics, Physics
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 precisely...

How Do We Tell Temperature?
Explore the science behind thermometers. Rather than measuring temperature, thermometers track the movement of heat from hot to cold. The installment of the ACS Reactions series examines the chemical response that make thermometers work.
