Enthalpy Teacher Resources

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.

A beautifully designed, eighteen-page chemistry tutorial awaits your learners. The main topics: enthalpy and entropy. By completing this lesson, students will be able to define these concepts, determine whether each is increasing or...

Accomplished chemistry learners set up a calorimeter and measured the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their tables for recording data. Consider...

Tired of long, tedious enthalpy calculations? Look no further than Hess' Law! Young chemists discover a shortcut using changes in enthalpy with a video from JFR Science. The narrator talks about the theory behind the law, then performs...

Where does the heat come from in hand warmers? Learn about enthalpy, the change in energy in a system, to see that when chemical bonds are broken or formed, energy moves into and out of a system because of chemical reactions. 

Learn the facts about types of wax! Partnered pupils determine the enthalpy of combustion for traditional paraffin candles, as well as soy-based candles. The activity focuses on calculations and compares the environmental impact of both...

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....

My room isn't messy — it's a scientific experiment in entropy! Scholars investigate entropy, enthalpy, and spontaneity through a guided procedure and set of questions. The lesson connects the Second Law of Thermodynamics, energy...

In this thermodynamics worksheet, learners calculate the change in enthalpy for several given chemical equations provided. Students specify if the reaction was endothermic or exothermic in nature.

In this chemistry video, Sal takes a closer look at what happens to the change in enthalpy during a chemical reaction. He points out that the enthalpy change, given constant pressure, becomes the heat added to the system at that constant...

An entertaining presentation introduces both enthalpy and entropy. It explains equilibrium as the balance between these two measures and provides simple diagrams and graphics for additional clarity.

Two animated slides explain the decomposition reactions that occurs within a catalytic converter. An enthalpy diagram is displayed. Hess's Law is demonstrated. Finally, the analogy of football is used to explain Hess's Law. This...

In this enthalpy worksheet, students calculate the combustion for propane and find the enthalpy of the reaction. They discuss entropy and free energy.

In this enthalpy of reactions learning exercise, students use a known amount of copper (II) sulphate solution and an excess of zinc powder to calculate the reaction's enthalpy change. Students measure the temperature change throughout...

In this enthalpy equation worksheet, students are given 3 examples of chemical reactions. Students then respond to 4 practice problems and 1 challenge problem in regard to heat and energy change and release.

Stephen Perry invented and patented the modern rubber band in 1845. Young scientists put his discovery to work as they use rubber bands to observe entropy and enthalpy. They determine the change in free energy to figure out if it...

Max Born and Fritz Haber developed the Born-Haber cycle in 1916, which is used for measuring enthalpy that otherwise couldn't be measured. Young scientists solve four matching puzzles using their knowledge of the stages, standard...

Melting ice seems pretty easy, right? But what's actually happening is much more complex! Introduce the class to enthalpy calculations using a video tutorial. The narrator explains and performs the calculations that show the energy at...

In this chemical reactions activity, students calculate the enthalpy required to produce a specific mass of product. This activity has 4 problems to solve.

In this chemistry worksheet students complete chemical equations by calculating what the ending formula will be and balance equations. 

In this chemical reactions worksheet, students use a standard enthalpy table to find the enthalpy of reaction for list of different fuels. This worksheet has 4 problems to solve.

In this enthalpy and entropy learning exercise, learners read about the differences between enthalpy and entropy and answer three critical thinking questions about the reading.
