AP Chemistry-Thermochemistry

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

More than a week's worth of investigation is provided in this source. Physical science stars experiment to describe specific heat, conduction, convection, and radiation. They also discover the relationship between mechanical and thermal...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

Examine the energy transfer of phase changes through diagrams. The second slide show in a series of seven presents the information related to energy and phase changes. It includes the effect of pressure on phase changes.

Everything around you is related to chemistry and more specifically, the energy within a system. The video explores how energy, in its different forms, changes after conversion — given off as heat or absorbed as heat  in...

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...

Sal introduces students to Hess's Law. The law states that a process's energy change is independent of how we get from one state to another. He sets up a series of reactions and solves them to illustrate the principles behind Hess's Law....

Budding chemists achieve a basic understanding of the role of heat in chemical reactions. An online worksheet gives learners instructions and questions to answer as they investigate the Chem4Kids website and perform a hands-on lab...

Free energy, get your free energy here! Learners see that all organisms require free energy, which comes from the sun. The lesson explains the first two laws of thermodynamics and then analyzes metabolism, via glycolysis, on a very...
