Chemical changes alter the chemical makeup of a substance...
physical changes only change the way something looks, it does not modify the chemical properties.
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
A chemical change results in the formation of new substances with different chemical properties, while a physical change involves a change in appearance, state, or form of a substance without altering its chemical composition. Chemical changes are usually irreversible, while physical changes can often be reversed.
Physical.
A chemical change involves a rearrangement of atoms to form new substances with different chemical properties, while a change of state is a physical change where a substance transitions between its solid, liquid, or gas state without changing its chemical composition.
Buoyancy is a physical change, not a chemical change. It results from the relationship between an object's density and the density of the fluid it is placed in, causing the object to either float or sink.
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.

they are different because a chemical change is a change in which you apply heat to a object to change it in form physical change is when you change a form it size or shape but do not apply heat.So you will know the differnce because when you add heat to any object its a chemical change but expccpt boiling water
A physical change is reversible, a chemical change is not.
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.

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...)
Chemical change: the structure of the molecule is chenged. Physical change: the structure of the molecule is not changed.
