Yes. Outside very special experiments, matter (mass) can neither be created no destroyed.
Yes, both for physical AND chemical changes!
neither physical or changes its property
neither physical or changes its property
Mass is not created or destroyed in chemical or physical changes.
law of consevation of mass states that the total mass before a chemical reaction is the same as the total mass after the chemical reaction
The mass.
A physical property is part of the make up of something that has a physical mass. No decomposing is not a physical property but rather both a physical change and a chemical change hence changing the chemical properties . The physical change is when the mass changes due to the brake down of the chemical and physical properties.

Mass is not created or destroyed during chemical or physical changes.
The law that states mass cannot be created or destroyed in chemical or physical changes is the Law of Conservation of Mass, also known as the Principle of Mass Conservation. This law implies that in a closed system, the total mass remains constant before and after any chemical or physical process, even if the substances undergo a change in form or state.
A physical change to an object is a change in properties not involving the chemical makeup. In other words, a physical change is any change you can make to an object without changing the actual substance. (I.e. state of matter, size, shape, color . . .etc.) A chemical change is a change that forms a new substance through a chemical reaction. A chemical reaction is often signaled by bubbling or fizzing, but the only real way to prove a chemical reaction is by coming up with a new substance. So physical changes leave you with the same substance (slightly altered in appearance/texture etc.), but chemical reactions give you a new substance.
The transformation of dough into bread involves both physical and chemical changes. The physical changes include the expansion of the dough during baking due to the release of gases, while the chemical changes involve the reactions between proteins and starches in the dough leading to the formation of a stable bread structure.
