to classified weather it is a chemical or physical change :))
The most important are changes of phase: melting, boiling, freezing.
it undergoes change, cause these changes may be temporary and easily reversible or may permanent and very difficult to reverse.
I really dont know lol
sorry don"t know
chemical change = chemical reaction. ( the composition of matter always changes). In a chemical change the matter in one thing changes, for example you will know a chemical change has occurred when the color or odor has changes or when a new gas is given off.
The study of matter and the changes
Not unless there's something about the matter that you really need to know. Examples: -- If you need to know whether the matter will fit through the door, then it's important to measure its width and height. -- If you need to know whether the matter is safe to eat yet, then it's important to measure its internal temperature. -- If you're buying some of the matter and you need to know what it should cost, then it's important for somebody ... either the buyer or the seller ... to measure its length, weight, area, or volume.
Chemistry
The study of properties of matter and how it changes is called chemistry.
What important contribution did Lavoisier make to Dalton's atomic theory of matter? Lavoisier helped the atomic theory of matter, by stating that matter is not destroyed or created, it just changes form. Located inside the nucleus, has a positive charge, and 1 amu.
Chemistry - the study of the properties of matter and how matter changes
Scientists want to know all about matter and universe.Also this is important for all technologies.
