Zipping up a zipper is a Physical change , Because Just because you are unzipping it and zipping it back up it is still a zipper and it is not changing the look or the form of how it is!.
Physical duhhhh
Physical change
Physical
Chemical properties describe how a substance will undergo chemical reactions and with what. Chemical changes are when one or more substances change to some other substance or substances.
That is what I wanted to know, this is what i think? Some Physical changes: -You can shape lead -It dislovels Some Chemical changes: -It does NOT burn -It turns into Lead Oxide Those are some but I need help with the rest... and takers? This might also help you... Phyical-You do the change. Chemical-It changes it's self.
Chemical Change
Yes silicon can undergo physical and chemical changes.
chemical. it changes the actual composition of the rock. :)
It's so physical ! Because is a property indepedent of chemical changes.
You can tell the difference by knowing that a physical property changes shape and that a chemical property changes the substance.
Lustre is a physical property, because... Look up a few definitions of "chemical property." In every one you will find that it involves chemical reactions, or changes in the identity of a substance. Lustre (shininess) is a property that can be observed without any chemical changes to the substance, so it can't be a chemical property.
It is a chemical change
It is a physical property. Changes that occur in a material without changing the identity of the material are physical changes.
Chemical properties describe how a substance will undergo chemical reactions and with what. Chemical changes are when one or more substances change to some other substance or substances.
Physical change. The wax was solid and now it is a liquid. All phase changes are physical changes.
it is a chemical property because it changes the chemical structure of the molecules in the base
neither physical or changes its property
It is a physical CHANGE, not property. A property of matter is something like inertia.
the properties that change are physical and chemical properties!!! :)
Rusting is a chemical property because it is irreversible. It changes the identity of the substance.
