Transcript of endothermic baking soda and vinegar

Baking Soda & Vinegar Endothermic Reaction What's going on with the Vinegar and Baking Soda? How can you be adding heat to it, and the temperature goes down? What does the temperature of the solution have to do with determining whether this is an endothermic or exothermic reaction? Video Potential and Kinetic Energy. Photo - The vinegar and baking soda bubble, forming a gas, and a soupy white goop. - The vinegar and baking soda are changing from their individual molecular structures to a new molecular structure - the soupy white goop. - NOTHING! - The molecular structure of the vinegar and baking soda combined and reacting form kinetic energy. Baking Soda & Vinegar :) http://montessorimuddle.org/2012/07/25/endothermic-reactions-vinegar-and-baking-soda/ - Temperature goes down. - It absorbs it from the surrounding air. This is an endothermic reaction. - This molecular change requires energy (heat) which it absorbs from the room. - The problem is, it can't absorb it fast enough. - It needs more heat than it is getting, therefore the temperature goes down. -The only thing you need to know is that the reaction absorbed the heat from its surroundings, therefore it is endothermic. - The dropping temperature of the solution is just evidence that it is absorbing heat, and not giving it off. - Heat energy from the surroundings is required because in the process, they are also combining to form a new molecular structure which has potential energy (the goop). - The change from kinetic energy to potential energy requires heat. - So much heat is needed that the temperature drops because it can't get the heat fast enough.
