How would you classify the following events? event 1: water boils at 100 degrees celsius event 2: a nail rusts when left outdoors event 1 is an example of a chemical change and event 2 is an example of a physical change. event 1 is an example of a chemical change and event 2 is an example of a chemical change. event 1 is an example of a physical change and event 2 is an example of a chemical change. event 1 is an example of a physical change and event 2 is an example of a physical change.

 Event 1 is an example of a physical change and Event 2 is an example of a chemical change.

Explanation: Physical change is one in which there is no change in chemical composition of the substance. There is only a change in phase change.

Chemical change is a change in which there is a change in chemical composition and there might or might not be a phase change.

On Boiling, the water molecules remain bonded in the same form and only covert from liquid to gaseous form, thus is a physical change.

On Rusting of iron nail, the iron changes to iron oxide by combining with oxygen, there is a rearrangement of atoms and thus is a chemical change.
