9-11-2018 Chemistry work https://www.youtube.com/watch?v=jJeiYaSFCf0 watch the video above on railway buckling and explain the scientific reasoning behind why Railway bucking occurs and how atoms in the steal mixture used to make railway tracks behave before and during bucking. In your answer, state physical or chemical changes are responsible for this phenomenon. Students can have a class discussion and support their ideas by stating related facts to back their claim. Then students must write down and explanation supporting their claim that explains this observation.
