Defined as anything that has mass and takes up space.
A form of matter that flows, has a fixed volume, and takes the shape of its container.
Matter that has a definite shape and volume. The shape does not depend on its container and the particles are pack tightly together.
A form of matter that takes both the shape and volume of its container. Easily compressed.
A mixture that is not uniform in composition, if you were to sample on portion of such a mixture, its composition would be different from that of another portion. Example: salad
One that has a completely uniform composition and its components are evenly distributed throughout the sample. Example: salt water
The simplest form of matter that can exist under normal laboratory conditions. These cannot be separated into simpler substances by chemical means are are the building blocks for all other substances.
Substances that can be separated into simpler substances only by chemical means/reactions.
A change from one state (solid or liquid or gas) to another without a change in chemical composition. (can be reversed)
A process in which one or more substances are changed into one or more different substances. (cannot be reversed)
The Law of Conservation of Mass
In any physical change or chemical reaction mass can neither be created nor destroyed in an ordinary chemical or physical process, it is conserved. In every case, the mass of the products equals the mass of the reactants.
