Carmen is heating some water and trying to measure the temperature of water using a celsius thermometer. which measurement can she expect once the water begins to boil?

32°c
100° c
212°c
373°c

The 2nd option

Well a chemical change is when substances are combined and the final product is permanent

For example ... baking a cake is a chemical change because the ingredients in the cake can't be separated as separate substances like they were in the beginning

A physical change is where the substances isn't changes, but just the appearance.

For example... origami or cutting paper is considered a physical change because even though it was cut or folded it is still paper.  

One similarity is that the physical and chemical changes are categorized under characteristic changes
