Physical changes do not change the kind of matter or its properties. Ex. cut a piece of paper and you sill have paper.
Chemical changes cause the atoms to recombine and form new substances with different properties. Ex. burn wood, it isn't wood anymore, it is ash and smoke and heat energy. ASH wasn't there before burning.

∙ 11y agoNo. A change is either physical or chemical, but not both.
Wiki User
∙ 10y agoYes, as result of chemical rections physical properties or circumstances, like temperature, color, hardness, conductivity etc. etc. might change.

Is the reaction between aluminum and copper chloride a physical or chemical change?
All chemical reactions are chemical changes.
Why do you think the sublimation of dry ice and expansion of gases are not chemical reactions?
Because they are changes of state - physical changes - VERY easily reversed.
What are the physical and chemical changes of an apple?
If you cut an apple and keep, the colour changes to brown. This is physical change. Apple has iron (in the form of ferrous salts). The colour is due to the formation of harmful ferric compounds and this is a chemical change (conversion of ferrous to ferric).
Is reactions a chemical or physical?
Chemical reactions are chemical processes.
Are exploding fireworks an example of a physical or chemical change?
Explosions are a form of either combustion or decomposition (or both) reactions, and they are chemical changes.
Can chemical and physical changes be called chemical and physical reactions?
yes it can be called physical and chemical reaction
What reaction is in antacids chemical or physical?
Chemical reactions are of course chemical changes.
How else are nuclear reactions unlike chemical reactions?
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
What chemical reactions are reversible?
All physical changes are reversible.
What are physical and chemical changes from a to z?
All physical and chemical reactions , see text book from A to z .
Is bleaching a sheet and pillowcase a chemical change or physical change?
These are chemical reactions (changes).
Are physical changes chemical reactions?
No, physical changes normally refer to changes other than chemical reactions. If you have a loaf of bread and cut it in half, that is a physical change but not a chemical change. If you eat the bread and digest it, that is a chemical change.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
What are examples of chemical reaction?
Reactions that are not chemical reactions are physical reactions. These reactions involve a change in only the physical state of an element, not its chemical properties. Thus, physical changes include freezing, condensation, sublimation, hammering a metal into a sheet, cutting sodium metal, etc.
Can a physical change become a chemical change?
A lot of chemical reactions are initiated by physical changes - specifically, heating something.
Is the reaction between aluminum and copper chloride a physical or chemical change?
All chemical reactions are chemical changes.
What happens with the sulfuric acid and is it a chemical change or physical change?
The chemical reactions of sulfuric acid are chemical changes.
