The temperature drops to –14°C. True or false? This is an exothermic reaction. Conduct the experiment in a polystyrene foam cup. This insulates the mixture and makes the results more accurate.

Heat packs that contain iron and water packets: Exposing the solution to air results in the oxidation of the iron (creates rust). The oxidation of the iron is an exothermic process. Heat packs that ...

But first, let's try one more exothermic reaction ... Before you try the following experiment, make sure that you are wearing protective glasses and latex or rubber gloves. Do NOT handle these ...

This fun and bubbly experiment combines peroxide, yeast, and other stuff to demonstrate catalysts and exothermic reactions. Watch the heat-producing mixture bubble and overflow for up to half an hour.

All chemical reactions involve an energy change. We categorise reactions by the direction of this energy change. If energy is released by a reaction, the reaction is exothermic. If energy is absorbed ...

Two temperature probes were placed directly on the surface of the mannequin; one on the torso away from the heating packs and the other directly beneath the exothermic heating pack. The mannequin was ...
