Endothermic and Exothermic Reactions

The video tutorial explains the concept of chemical reactions, focusing on endothermic and exothermic reactions. Endothermic reactions absorb heat, while exothermic reactions release heat. Examples include melting ice for endothermic and lighting a match for exothermic. Photosynthesis is highlighted as an endothermic process where plants absorb heat energy. The tutorial emphasizes understanding reactions by following the movement of heat.
