A physical change to an object is a change in properties not involving the chemical makeup. In other words, a physical change is any change you can make to an object without changing the actual substance. (I.e. state of matter, size, shape, color . . .etc.)
A chemical change is a change that forms a new substance through a chemical reaction. A chemical reaction is often signaled by bubbling or fizzing, but the only real way to prove a chemical reaction is by coming up with a new substance.
So physical changes leave you with the same substance (slightly altered in appearance/texture etc.), but chemical reactions give you a new substance.
Chemical and physical changes are not similar.
Chemical change: a process in which the nature of molecules is changed.
Ex.: burning, precipitation, decomposition.
Physical change: a proces which don't imply a change in the nature of molecules.
Ex.: melting, boiling, freezing.
they both alter an object in some way or they both change there main object.
THE CORRECT ANSWER WOULD BE>>>> there is no change in the total mass involved in the change
i think its tat both changes require energy....
Chemical changes can cause physical changes (IE change color) however physical changes cannot cause chemical changes. Otherwise their is no similarity.
They are both used to classify substances.
Chemical broooooooooooooooo niga
it is a chemical change
Chemical I think
physical as the chemical structure does not change.
Physical - there are no chemicals involved
Chemical broooooooooooooooo niga

Dissolving is a physical process.
physical as the chemical structure does not change.
It is a physical process; on the other hand dissociation in water is a chemical process.

It's a physical change why are some people f$#@%ing stupid and saying a chemical change??
