Nope. All that happens in chemical reactions is that atoms are rearranged into new molecules or compounds. You can't destroy atoms in a chemical reaction so whatever you begin with is what you end up with.
During a physical change, the atoms remain bound to one another in their original molecular arrangement. If they were molecules they stay as molecules if they were in an ionic interaction they are still ionically bound.
The molecules may break bonds with one another. The water molecules may have enough energy to break the bonds that bound them to other molecules and become a gas.
Summary, atoms keep their original bonding before and after a physical change; molecules may or may not.
No. A physical change only changes the shape or texture of an object. A chemical change alters the atomic composition of an object.
They remain bonded to each other in their molecular arrangement
Only chemical reactions can rearrange the atoms.
yes they do...a physical change occurs only on the outside (appearance) of the substance but a change on the molecular level (molecules) would require a chemical change
Chemical
Chemical - It's the iron atoms reacting with the oxygen atoms in the air. For future reference, a chemical change is irreversible, whereas a physical change can be reversed, usually quite easily.
chemical and physical change.
Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
The mass can increase. The particles can arrange in different ways. The mass can decrease. The atoms can bond to different atoms.
A physical change is a change where the atoms might get separated but there is no change in it's chemical. It all depends on what you did with the atoms (For example, poisoning something is a physical change), and if the thing itself is edible.
Chemical
Chemical
The transformation of a liquid to a gas.
Temperature remains constant during the change in phase (physical state).
Change of state is always physical. You have not lost or gained any atoms. Therefore its physical.
Atoms have a negative charge when they gain electrons during chemical changes. Atoms are a basic unit of matter, and everything is made of atoms.
atoms, are rearranged during a chemical change.

what does physical change mean
No the substances like molecules donot chane during physical change .
During chemical reactions atoms remain unchanged.
