Endothermic Reaction

The video explains exothermic and endothermic reactions, focusing on an endothermic reaction demonstration using barium hydroxide and ammonium thiocyanate. The setup involves a digital thermometer and a beaker on a wet piece of wood. As the reaction proceeds, the temperature drops significantly, illustrating energy absorption from the surroundings. The video details the chemical process, emphasizing bond formation and breaking, and concludes with the reaction's impact on temperature, causing the beaker to freeze to the wood.

What is the significance of bond formation and breaking in chemical reactions?

How does the temperature drop affect the state of water in the experiment?

What occurs when the beaker freezes to the wood during the experiment?
