When a car is turned into a wreck, this involves a physical change because the molecular composition of the car doesn't change. After the crash it will still consist of steel, petrol, etc. However, if one was to set fire to the car, it would undergo a chemical change: its molecular composition would change because the molecules would bind with the oxygen molecules in the air.
