Term | Definition |
States of Matter | liquid, gas, solid, are the different kinds |
Gas | no fixed volume or shape |
Liquid | a distinct volume independent of its container but has no specific shape |
Solid | a definite shape and volume |
Solutions | groups of molecules that are mixed up in a completely even distribution |
Compound | substances composed of two or more elements |
Pure Substance | matter that has distinct properties and a composition that doesn't vary from sample to sample |
Elements | cannot be decomposed into simpler substances (building block) |
Mixture | combinations of two or more substances in which each substance retains its own chemical identity |
Homogenous mixture | solutions are also mixtures, but all of the molecules are evenly distributed |
Alloys | mixture of two or more metals |
Emulsions | mixture of oils and waters |
Solute | the substance to be dissolved |
Solvent | the one doing the dissolving |
Solubility | the amount of solute that can be dissolved by the solvent |
Colloids | solutions with much bigger particles, usually foggy or milky when looked at |
Molecule | general term used to describe atoms connected by chemical bonds, every combination of atoms is a molecule |
Covalent compounds | happen when the atoms share the electrons |
Ionic compounds | happen when electrons are donated from one atom to another |
Electrons | negatively charged particles of the atom |
Matter | anything that has mass and takes up space |
Physical forces | create the changes (alone cannot break down compounds) |
Chemical Forces | bonds are built and broken down |
Heterogeneous mixtures | in which the two or more substances that form the mixture are not evenly distributed |
Suspensions | heterogeneous fluid mixtures containing solid particles large enough for sedimentation |
