Exothermic Vs Endothermic Reactions Explained

This animation shows bonds breaking and forming during chemical reactions, using 3D molecular visuals and a simple lab demo (like dissolving salts) to reveal heat released or absorbed. A thermometer graphic tracks temperature rise in exothermic reactions and drop in endothermic ones. Key Chichewa terms support English narration, helping students without lab access grasp energy changes clearly and intuitively.
