Exothermic vs. Endothermic Reactions: What's the Difference? 🔥❄️
Guided Notes
3 key concepts
- 1
Exothermic reactions release heat, causing the surroundings to become warmer, while endothermic reactions absorb heat, leading to a decrease in temperature.
- 2
In an investigation of chemical reactions, measure temperature changes to classify reactions; a temperature increase indicates an exothermic reaction, while a temperature decrease indicates an endothermic reaction.
- 3
When planning an investigation, ensure accurate temperature measurements by using a thermometer and controlling variables such as insulation to minimize heat exchange with the environment, thus isolating the heat swap of the reaction.
