As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

In this thermodynamics worksheet, students fill in the blanks with terms related to specific heat, calorimetry, phase changes, enthalpy, entropy and free energy.

In this entropy learning exercise, students define entropy and determine if reactions are exothermic or would occur spontaneously. This learning exercise has 10 problems to solve.

In this thermodynamics worksheet, students calculate the change of entropy and standard free energy change for given reactions. Students write expressions for the thermodynamic equilibrium constants for reactions. This worksheet has 10...

In this chemical reaction worksheet, students define equilibrium, determine what affects the progress of a reaction, and compare and contrast entropy and enthalpy. This worksheet has 5 fill in the blank, 5 short answer, and 16 problems...

Students listen to a lecture on the collision theory. They discuss the reactant and product changes during a chemical reaction. Students are taught the factors affecting reaction rates. They complete a lab on entropy, heat and free...

Through critical thinking, students realize that spontaneous events happen in a certain order. This lesson presents an examination of the Second Law of Thermodynamics using a thought story, rubber band inquiry, discrepant event and lecture.

The New Mexico Solar Energy Association provides an article entitled, "Electrolysis: obtaining hydrogen from water - the basis for a solar-hydrogen economy". The article is medium size in length with pictures and charts throughout to help.
