Is it possible to predict physical or chemical changes? i don't really understand how to predict a change from the information my science teacher is giving me. the textbooks say what physical and chemical changes are but not how that means we can predict them.

Yes, it is possible to predict physical or chemical change.

Explanation:

Physical change -there is a difference in the appearance(shape, color, texture), or simple display of a sample of matter without a change in composition(what it is made of)

Chemical change- When bonds are broken and new ones are formed a chemical change occurs.

for example- When two or more reactants are mixed and a change in temperature, color, etc. is noticed, it is a chemical change.

BUT changing a color of a car for example is not chemical but physical because you are not messing or changing the inside.
