Worked Solution & Example Answer:A student holding the test tube notices that it cools down during the reaction - Junior Cycle Science - Question b - 2019
Step 1
Is this reaction an example of an endothermic or an exothermic reaction?
Answer
This reaction is classified as an endothermic reaction. An endothermic reaction is one that absorbs heat from the surroundings. The observation of the test tube cooling down indicates that heat is being taken in from the environment, which is characteristic of endothermic processes.
