A chemical property of wood is that it is flammable. A physical property is that it is an insulator of heat.
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.
This would be a chemical change. The other type would be a physical change. In a physical change the identity of the material does not change.
Wood is a material (substance) not a chemical compound (it is not a pure substance made of one compound) and surely it is not a change at all, neither chemical nor physical.
ChemicalTo determine it, you must alter the identity of the substance. See the Related Questions link to the left of this answer: "What is the difference between a chemical and physical property?"PhysicalElements cannot be altered, without disrupting the physical structure of the atom, so the atomic structure between the protons, neutrons, and electrons are physical.Barney9So which one is it...? Chemical or physical?~Physical. Barney9's answer was a little confusing.. but overall, you can identify an element without disrupting the atomic structure of it's atoms.
B: Physical Property
it is chemical change

well, first of all you would need to know what the raft is being made of. take wood for an example. so you need to list the physical and chemical properties of wood. physical properties can be observed or measured. so one physical property of wood might be it's volume, or it's state, or it's strength, or it's hardness, or many other things that can be measured or observed. next you need to find the wood's chemical properties a chemical property describes how a substance changes into a new substance, either by combining with other elements or by breaking apart into new substances. so a chemical property of wood might be it's flammability, or it's reactivity.
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, chemical is one that affects the chemical make up of the substance.
True. Flammability is a chemical property of matter. It is not a physical property of matter. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases. After burning, it is no longer wood.
It is a change of a physical property - for example the variation of temperature.
That is a chemical property. A physical property could be its mass, volume, density, physical state, or that it can tear easily. A physical property is one that does not change the chemical composition of the substance.
physical: electrical insulatorchemical: composed mostly of complex carbohydrates
This would be a chemical change. The other type would be a physical change. In a physical change the identity of the material does not change.
A physical property is one that can be changed without altering the chemical formula of the substance, e.g., gas to liquid. A chemical property is one that is unique to that substance and altering it will change that substance chemically, e.g. density or molar mass.
Wood is a material (substance) not a chemical compound (it is not a pure substance made of one compound) and surely it is not a change at all, neither chemical nor physical.
