1. 1

   Exothermic reactions release heat, causing the surroundings to become warmer, while endothermic reactions absorb heat, leading to a decrease in temperature.

2. 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. 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.

“Describe an example of an exothermic reaction and an endothermic reaction, explaining how each reaction demonstrates the transfer of heat.”
