Investigating Temperature Changes in Chemical Reactions

The video is a tutorial on how to investigate temperature changes in chemical reactions, specifically focusing on the concepts of exothermic and endothermic reactions. The video explains the definition of the two terms and provides examples of each. It then discusses the steps required to carry out an investigation into temperature changes in chemical reactions, using two different reactions as examples. The video emphasizes the importance of waiting for temperature readings to become constant and using polystyrene cups to reduce energy transfers between the contents and surroundings to ensure accurate measurements. Overall, the video provides a helpful guide for conducting the required practical activity in chemistry.
