the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.

A physical change is reversible, a chemical change is not.
Physical change involves a change in the form or state of matter without changing its chemical composition, such as melting ice to water. Chemical change involves a change in the chemical composition of a substance, resulting in new products being formed, such as burning wood to produce ash and smoke. Observing changes in properties, such as color, odor, or temperature, can help distinguish between physical and chemical changes.
A chemical change results in a change in chemical composition, while a physical change does not.
a physical change is reversible but a chemical change is irreversible
Physical change is a change in the structure. Chemical change is a change in the composition. Melting is a physical change. Complexing is a chemical change.
chemical
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Physical
One distinguishing feature between physical and chemical changes is that a physical change can be reverse or turn back to its original form, but chemical change cannot be return to its form because the material change.
