Washing shoes is a physical change because the composition and chemical structure of the shoes remain the same before and after washing. The change is reversible and does not alter the material at a molecular level.
Washing clothes is a physical change, not a chemical change. The dirt and stains on the clothes are being physically removed, but the molecular structure of the clothes remains the same.
The key here is what happens to the matter. Does it change into a different material or just change shape? If the metal changes into a new substance like iron into rust then it would be chemical but this is definitely a physical change. - - - - - Car crashes can cause both physical and chemical changes. The bending of the car is a physical change, but if the wreck catches fire that's a chemical change.
i tink that it is a physical change
Smashing a car is a physical change because it alters the physical form or shape of the car but does not change its chemical composition. The car can still be repaired or restored to its original state by reshaping the damaged parts.
A crashing car is a physical change because the collision alters the car's shape and form, but the chemical composition of the materials remains the same. No new substances are produced as a result of the crash, so it is considered a physical change.
Am I cute?

A car crash is physical.
Spray painting a car involves a chemical change because the paint chemicals react to form a new substance that bonds to the surface of the car's body. This is different from a physical change, where the paint would simply be a new layer on top of the car without a chemical reaction occurring.
The car become modified.
