a change in the chemical properties of substance results in a?
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
What doesnt change during the composition of a substance?
The composition of a chemical compound is not changed during a physical change.
How does burning produce new materials?
Burning is a term which generally describes the chemical reaction combustion. Combustion always involves the reaction of a substance with an oxidizing agent to yield products which are either components of the original substance or different compounds which contain the same atoms. So, the process of combustion always yields a substance which is different from the original compound (i.e. forms a new substance) along with a lot of heat. This heat allows the substance to continue burning until no reactants remain or something inhibits the reaction - usually by removing access to one of the reactants or removing energy form the system. Most organic matter will burn to produce large quantities of carbon dioxide and water.
Does the mass change when something goes from solid to a liquid?
No, the mass of a substance remains constant when it changes from a solid to a liquid. The particles are simply rearranging from a fixed pattern in a solid to a more fluid arrangement in a liquid, but the total number of particles remains the same.
What is a chemical change of matter?
when you heat up water then it turns into water vaporThe above is NOT a chemical change but a PHASEchangeIf you disassociate water into Hydrogen and Oxygen with electrolysis that is a chemical change.If iron rusts, that is a chemical change too (but several a rather complex reactions)

What to do if the boy doesnt know you?
Make sure that changes, and changes fast. If you want any chance with him you're going to have to get out of that admiring in the distance phase and become a part of his life, be it just an acquaintance, if he digs you he'll make some effort too.

What doesnt change on an object when gravitational force changes?
mass
Is the fermenting of cheese a physical change?
"A physical change is any change not involving a change in the substance's chemical identity. Matter undergoes chemical change when the composition of the substances changes: one or more substances combine or break up (as in a relationship) to form new substances" From This I gather that its a physical change as the cheese isn't changed into another substance, The cheese doesnt change, for example it doesnt taste or smell different, But its physical propertys do change it looks different

it doesnt
Why doesnt sand dissolve?
Mainly because it's composed primarily of silicon (the same substance as glass), a substance that's insoluble in water.
