Classification of Matter

anything that has a mass and takes up space

solid, liquid, gas

holds shape, fixed volume

shape of container, free surface, fixed volume

shape of container, volume of container

-matter is made up of particles that are extremely small -these particles are always moving -when the temperature increases, the movement of the particles increases -the particle are held together by forces

smallest particle of matter, cannot be divided chemically rare to find atoms alone, in nature usually bound to other atoms

bounded atoms (2 or more) held together by chemical bonds

water, ammonia, carboon dioxide, methane

made up of only one type of particle (atom or molecule) , possesses its own properties

elements and compounds

a pure substance contains only one type of atom, not possible to separate into other substances

hydrogen (H), carbon (C), oxygen (O)

oxygen gas (O2), hydrogen gas (H2)

pure substance contains ( a type of molecule) at least 2 different type of atoms that are chemically bonded, can be separated using chemical techniques

water (h2O), table salt (NaCl), glucose (C6H12O6)

2 types of atoms or molecules are mixed together without chemical bond

heterogenous and homogenous

at least 2 substances that CAN be seen with naked eye

at least 2 substances that CANNOT be seen with naked eye

homogeneous mixture, impossible to distinguish between different substance

-solute -solvent

substance that dissolves in another substance, usually a smaller quantity

substance can dissolve the solute, usually larger quantity
