Final answer:
An exothermic chemical reaction releases heat, causing the temperature to rise, while an endothermic chemical reaction absorbs heat, causing the temperature to decrease.
Step-by-step explanation:
An exothermic chemical reaction releases heat, causing the temperature to rise. In this type of reaction, energy is being given off to the surroundings. An example of an exothermic reaction is the combustion of wood, where heat and light are produced.
On the other hand, an endothermic chemical reaction absorbs heat from the surroundings, causing the temperature to decrease. Energy is being taken in during this process. An example of an endothermic reaction is the reaction between baking soda and vinegar, which results in a cold pack getting colder.
