Document Summary
The structure of those particles determine the properties of matter bind together to form molecules. Chemistry= the science that seeks to understand the properties of matter by studying the structure of the particles that compose it. Substance= a speci c instance of matter (ex. sand, water, air) State of matter: solid/liquid/gas (s/l/g) depends on relative position and how strongly the atoms interact with one another. Xed volume & rigid shape slightly weaker attractions b/t particles than solids. Xed volume but not xed shape --> assume shape of container particles weakly attracted to each other large spaces between the molecules in a gas make gases compressible always assume the shape & volume of their container. Composition of matter: depends on the type of particles. Pure substance = made up of only one type of particle. Mixture= composed of two or more particles in proportions that can vary from one sample to another.
