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.
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.
A physical change is reversible, a chemical change is not.
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...)
chemical change is easily reversible whilst physical is not reversible
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

A physical change is reversible, a chemical change is not.
a physical change is reversible but a chemical change is irreversible
a physical change is reversible but a chemical change is irreversible
The diffence between chemical and physical is that ones chemical and ones physical!!
what is the difference between a physical change and a physical property
A change of state is a physical change while a chemical change is not
A physical change involves a change in the appearance or state of matter without affecting the chemical composition, such as melting ice into water. A chemical change involves a transformation of the chemical composition of a substance, resulting in the formation of new substances with different properties, like burning wood to produce ash.
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...)
chemical change is easily reversible whilst physical is not reversible
