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.
its because of the liberation of electrons in the submolecular level of a quimical reaction

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.
it is an change that change the change
no it does not change at all no it does not change at all better answer no it does not change at all
