It is possible to predict a physical change or chemical change because they have very unique properties and differences.
A physical change is a change that alters the physical properties of matter especially form and state.
A chemical change is a change in which new kinds of matter is formed.
Here are some of the properties and indicators of the these change;
- A physical change is easily reversible
- Chemical changes are not easily reversible
- Physical changes leads to the production of no new kind of matter.
- Chemical change produces new kinds of matter
- Physical change involves no change in mass
- Chemical change involves a change in mass
- Physical change requires little to no amount of energy
