Disung dishing chemical and physical change There ar sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample. You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change. Each sketch is drawn as if the sample were under a microscope so powerful that individual atoms could be seen. Also, you should assume that you can see the entire sample, and that the sample is in a sealed box, so that no matter can enter or leave. Sample of Substance X Change 1 Change 1 is: impossible O a physical change O a chemical change Change 2 Change 2 is: O impossible O a physical change. O a chemical change. Change 3 Change 3 is: O impossible O a physical change O a chemical change
