Exothermic and Endothermic Reactions: Experiments and Definitions

The video tutorial explains exothermic and endothermic reactions through definitions and experiments. It demonstrates an exothermic reaction using hydrochloric acid and sodium hydroxide, showing an increase in temperature. An endothermic reaction is demonstrated by dissolving potassium chloride in water, resulting in a temperature decrease. The video concludes with steps to identify reaction types based on temperature changes.
