First let me define covalent and non-covalent bonds.
Covalent bonds are bonds BETWEEN the atoms of a chemical - the atoms share electrons.
Noncovalent bonds are the interactions between atoms (and chemicals) that do NOT involve sharing of electrons. (hydrophobic, hydrophilic, and ionic bonds are non-covalent bonds)
Physical Change: breaking wood in half, melting ice, deflating a balloon, heating/cooling something (burning NOT included), dissolving something (as long as it does not react with solvent). Physical changes do not make or break covalent bonds. Physical changes only break/make non-covalent bonds (such as hydrophobic, ionic or hydrogen bonds).
Chemical Change: burning something, changing the actual chemical makeup in any way - usually by reactions like redox (reduction-oxidation reactions), decomposition and combustion reactions among others. Chemical changes do make and/or break covalent bonds. If the breaking and/or making of covalent bonds occurs - the change is chemical - since you are actually changing the chemical into something new.

What is the difference between chemical change and physical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
What is the difference between a physical and chemical change?
A physical change is reversible, a chemical change is not.
Difference between chemical and physical change?
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
What is the difference between a chemical and a physcial change?
chemical change is easily reversible whilst physical is not reversible
What is the difference between chemical change and a physical change?
a physical change is reversible like freezing or melting but a chemical change is irreversible like baking a cake, once it's been cooked, you can't get your cake mix bake

What is the difference between a chemical and a physcial change?

What is the difference between a chemical change and physical change?
A physical change changes the physical properties of an element like color where chemical changes change the chemical properties of an element and usually can't be undone.
What is the scientific difference between a physical change and a chemical change?
A physical change doesn't modify the chemical nature of the molecule.A chemical change transform the molecule A in another molecule B.
What is one major difference in a physical change and a chemical change is?
Physical change, changes the appearance or the surface. Chemical change, changes the minerals inside the object. Physical deals with the appearance and the surface. Chemical changes the structure of the minerals inside the object.
How does a chemical differ from a physical change?
A physical change is different than a chemical change, because in a physical change, the composition of the matter did not change. While in a chemical change, the composition of the matter did change.SO basically, the composition of the matter does not change is the difference between a physical change and a chemical change.yes
