pure substance

a sample of matter, either a single element or a single compound, that has definite chemical and physical properties

heterogenous mixture

A mixture with uneven distribution of different substances, solids, liquids, gases.

homogenous mixture

a mixture in which the composition is uniform throughout


a homogeneous mixture of two or more substances


a mixture in which fine particles are suspended in a fluid where they are supported by buoyancy


a mixture in which the particles are dispersed throughout but are not heavy enough to settle out

physical property

a property used to characterize physical objects


a liquid's resistance to flow


the ability of a material to allow either heat or electricity to flow through it


the property of a metal that indicates that it can be bent and rolled into sheets

melting point

physical property - the temperature at which a substance changes from a solid to a liquid


a process that separates materials based on the size of their particles

physical change

a change from one state (solid or liquid or gas) to another without a change in chemical composition

chemical change

a change that produces matter with a different composition than the original matter


the ability to burn

chemical property

a property used to characterize materials in reactions that change their identity


a solid that forms and settles out of a liquid mixture


of definite shape and volume


a substance in the fluid state of matter having no fixed shape but a fixed volume


matter that does not have a definite shape or volume

pressure vs volume

high pressure low volume

temperature vs pressure

temperature inccrease pressure increases

volume vs temperature

volume increases temperature decreases

phase change

a change from one state (solid or liquid or gas) to another without a change in chemical composition
