lets say you have a brick and you brake it in have. that is a physical change because it changed its apperence or physical charictaristics.
a chemical change is when it changes to solid to liquid. Or liquid to gas. Like melting an ice cube is a chemical change because it was a solid now its a liquid.
A physical change is when something changes to a different state (solid, liquid or gas), but it does not change chemical composition; for example, it remains H2O. In a chemical change, new chemical bonds are formed.
Yes, reactivity to vinegar is an example of a physical property because it describes how a substance behaves without altering its chemical composition. In this case, the reaction between vinegar and a substance demonstrates a physical change rather than a chemical one.
A physical change is melting.A chemical change is combustion.
Boiling is a physical change, not chemical.
Vaporization is a physical change, not chemical.
Concrete hardening is an example of a chemical change. When water is added to the cement mixture, a chemical reaction occurs between the water and the cement particles, resulting in a new substance with different properties than the original components.

Physical. If water evaporates, it is still water. It does not change into a different substance. A Chemical change is when something changes into a different substance. For example, when wood is burned, it changes into a different substance(ash).
Chemical change.
In a physical change, the substance is still the same substance after the change. But in a chemical change, the substance became another substance with different properties from the original substance.Physical change is changing the appearance of something. Example - Rip a piece of paper - physical change. Burn gasoline - chemical change.
How something reacts depends on a lot of different things. Physical reactions are much different than chemical reactions for example.
No, a decaying compost pile is not an example of a physical change. The process of composting results in a different physical appearance or state -- which is physical change -- but it is not reversible and necessitates a change in structure -- which is chemical change.
Rusting is the oxidation of a metal and is an example of a chemical change.
