all particles in matter are identical (fixed composition)

two or more substances physically mixed together

simplest form of matter from which more complex substances are made (listed on the PT)

two or more atoms chemically bonded to one another in a fixed proportion

temperature at which a solid becomes a liquid

temperature at which a liquid becomes a gas

a fluid's resistance to flow; a physical property only of liquids

a measure of how well a solute dissolves in a solvent

measure of compactness or consistency of a material

how easily a substance will set on fire

how easily a substance reacts, usually with an acid or base

how easily a substance reacts with oxygen

process by which the atoms of one or more substances are rearranged to form different substances

Matter is neither created or destroyed during a chemical change. It only changes forms.

measure of the average kinetic energy of particles in an object

matter composed of positively and negatively charged particles with extremely high kinetic energy

the amount of energy needed to turn a solid into a liquid at its melting point

the amount of energy needed to turn a liquid into a gas at its boiling point

the phase/state transition from liquid to gas

caused by pressure change, occurs only at the surface of a liquid

caused by a temperature change, occurs throughout the liquid

a homogeneous mixture that has the same composition, color, density, and taste throughout.

substance that is dissolved

substance that is doing the dissolving

solution of metals dissolved in other metals
