The most important are changes of phase: melting, boiling, freezing.
Chemistry is the scientific study of the composition structure and properties of matter and the changes that it undergoes.
chemical change.
no
Yes, when matter undergoes a chemical change, the composition of the matter changes at the molecular level. New substances are formed with different chemical properties than the original substances.
Energy.
Gas
When matter undergoes a chemical change, the composition of the matter changes. When matter undergoes a physical change, composition of the matter remains the same.
A chemical change involve a change of composition.
The scientific study you are referring to is called chemistry. Chemistry explores the composition, structure, and properties of matter, as well as the changes matter undergoes during chemical reactions. It is a fundamental science that helps us understand the world at the molecular level.
yes it does
Chemistry
When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
