A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.
SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.
yes
well that only depends on the form
yes
Ionization is a chemical change, as it involves the process of gaining or losing electrons to form charged particles (ions). This differs from physical changes, which do not alter the chemical composition of a substance.
Physical change is the change in which only physical properties changes ,like color, hardness, density etc. Chemical changes affect the composition as well as chemical properties of matter and result in formation of new substance. Examples of chemical changes are : Burning of coal Burning of Paper Electrolysis of water
A physical property can be observed without changing what the substance is made of. A chemical property can only be observed by altering a substance through a chemical change.
undergoes a chemical reaction, resulting in the formation of new substances with different chemical properties. This usually involves a rearrangement of atoms and the breaking and forming of chemical bonds, leading to a change in the composition and structure of the material. In contrast, physical changes only affect the physical state or appearance of a substance without altering its chemical composition.
In a physical change, the substance retains its chemical composition, but its physical state may change, such as melting or freezing. In a chemical change, the substance undergoes a change in its chemical composition, resulting in the formation of new substances.
A physical change
Physical change of the paint, not the door.
it is a chemical change
An acid is a chemical compound, not a physical or chemical change.
It is a physical change.Density is not a chemical property. Instead, it is a physical property.
