physical change
a change in size, shape or the state of matter is a physical change. True for A+.
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.
No. Any change of state (solid to liquid, liquid to gas, etc.) is a physical change.
No, the fat solidifying in a chip pan is a physical change, not a chemical reaction. The change from liquid fat to solid fat is due to the cooling of the fat, not a chemical transformation.
Yes becasue when the atoms inside the wax start to change, they all form and become a solid. this is what is now called replacement.
Solidifying.

Solidifying or freezing
Frying bacon is a chemical change. In addition to simply heating the bacon, frying it causes certain molecules to react and change. For instance, some protein molecules may be broken down. This is why cold fried bacon tastes different than cold raw bacon.
This observation refers to a physical change. The melting and solidifying of the wax is a reversible process that does not change the chemical composition of the wax molecules.
Yes, this is a chemical reaction in the sense that a lowering of the temperature causes fat to move from a more liquid form to a more solid form.
Crumple is a physical change.
This is properly called "freezing". Occasionally, it can be called "solidifying", but that's not really correct.
