How does one kind of matter become a different kind of matter?
when it breaks into pieces.
when it goes through a physical change.
when it goes through a chemical change.
when it becomes frozen.
When matter goes through a physical change, such as melting, freezing, evaporation, or condensation, it can become a different kind of matter but retains its chemical composition.
On the other hand, when matter undergoes a chemical change, such as a reaction with another substance or a change in its molecular structure, it transforms into a different kind of matter with a new chemical composition.
So, matter can become a different kind of matter through physical changes or chemical changes.
