With an overview of topics related to chemical equilibrium, this site provides a foundation to a study of thermodynamics and energy. The site specifically addresses free energy and the Gibbs function.

Students act as engineers to learn about the strengths of various epoxy-amine mixtures, and observe the unique characteristics of different mixtures of epoxies and hardeners. Student groups make and optimize thermosets by combining two...

In this activity, students use knowledge of specific heat capacity to mix together hot coffee and cold milk to create a solution of coffee at a desired temperature. In this randomized problem, each student is given a different final...

Based on information from Part 1 of the Hot/Cold Pack Problem, design a hot/cold pack.

This activity provides a demonstration of Hess's Law using three reactions: the solubility NaOH in water, the solubility NaOH in HCl, and the reaction of a solution of HCl and a solution of NaOH.

Measure and compare the heat capacity of an unknown liquid with an unknown density.

In this chemistry lab, learners investigate two types of reactions and answer questions relating to exothermic and endothermic reactions.

With an overview of topics related to chemical energetics, this site provides a foundation to a study of thermodynamics and calorimetry. Other topics covered include calorimeter constant, bomb calorimetry, and more.

This resource provides information on a rather interesting spontaneous endothermic reaction, involving cobalt (II) chloride and thionyl chloride.

A nice juxtaposition of endo- and exothermic reactions. Outlines two demonstrations. Barium hydroxide, sodium acetate, ammonium nitrate, ammonia.

Assess your ability to distinguish between exothermic and endothermic chemical reactions with this interactive multiple choice quiz. Receive immediate feedback to your answers.

Explanation of Gibbs Free Energy and Spontaneity. Includes formulas and examples.

[Free Registration/Login may be required to access all resource tools.] Students determine the temperature at which a reversible reaction will achieve equilibrium by using the Gibbs free energy equation, and then describe the...

At this site, the student can find out thermophysical properties of different fluids and gases.
