What Are Endothermic & Exothermic Reactions

This video tutorial explains exothermic and endothermic reactions, highlighting their differences in energy transfer. Exothermic reactions release energy, causing surroundings to heat up, while endothermic reactions absorb energy, making surroundings cooler. Examples of exothermic reactions include neutralization and respiration, whereas endothermic reactions include electrolysis and photosynthesis. The video also covers physical processes like melting and freezing, explaining their energy dynamics. Key points include the energy curves and the commonality of exothermic reactions.
