A chemical change occurs when a new chemical substance forms after a specific reaction between two initial substances. Some examples of chemical changes are iron rusting and combining baking soda with vinegar to produce carbon dioxide gas.
A phase change is an example of a physical change, not a chemical, nuclear, or covalent change. During a phase change, the substance undergoes a change in state (solid, liquid, gas) without any change in its chemical composition.
A physical change that does not produce a new substance is called a reversible change. This means the change can be undone by reversing the process, such as melting or freezing.
The change in the crushed can appearance was caused by a physical change. When the can is crushed, the arrangement of its particles is altered, but no new substances are formed.
Alcohol vaporizing is a physical change because it does not involve a change in the chemical composition of the alcohol molecules. It is simply a phase change from liquid to gas.
No, flattening is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas flattening simply changes the shape or appearance of the object.

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.

No, change of state is a physical change.
no a change in shape is physical change
A change of state is a molecular change.
change change as in 'small change' or change for a larger bill = monnaie
Social change is a change in society. Cultural change is a change in culture.
