States of Matter
|
Three forms of matter are, solids, liquids, and gases.
|
|
|
Gas
|
Also known as vapor, has no fixed volume or shape; rather it conforms to the volume and shape of its container.
|
|
|
Liquid
|
Has a distinct volume, independent of its container but has no specific shape.
|
|
|
Solid
|
Has both a definite shape and a definite volume.
|
|
|
Pure Substance
|
It is matter that has distinct properties and a composition that doesn't vary from sample to sample.
|
|
|
Elements
|
Cannot be decomposed into a simpler substance.
|
|
|
Compounds
|
Substances composed of two or more elements and contain two or more kinds of atoms.
|
|
|
Mixtures
|
Combinations of two or more substances in which each substance retains its own chemical identity.
|
|
|
Components
|
The substances that make up a mixture.
|
|
|
Law of constant Composition
(Law of definite proportions) |
The observation that the elemental composition of a pure compound is always the same.
|
|
|
Alloys
|
A mixture of two or more metals.
|
|
|
Reactions
|
When a chemical structure changes.
|
|
|
Solutions
|
Mixtures, but all of the molecules are evenly spread out through the system.
|
|
|
Emulsions
|
Another type of mixture, like oil and water.
|
|
|
Solute
|
The substance to be dissolved.
|
|
|
Solvent
|
The substance doing the dissolving.
|
|
|
Solubility
|
The amount of solute that can be dissolved by the solvent.
|
|
|
Colloids
|
These are solutions with much bigger particles.
|
|
|
Molecule
|
The general term used to describe atoms connected by chemical bonds.
|
|
|
Physical Forces
|
The force that creates the change in the compound.
|
|
|
Chemical Forces
|
This happens when a compounds bonds are built and broken down.
|
|
|
Filtration
|
The separation between two or more substances.
|
|
|
Distillation
|
A process in which one substance is being boiled away from another and then collected.
|
|
|
Ionic Bond
|
A chemical bond between two atoms where one or more electrons are passed from one atom to another.
|
|
|
Suspensions
|
Heterogeneous fluid mixtures containing solid particles with large enough sedimentation.
|
|
|
Homogenous Mixtures
|
In which two or more substances, that form the mixture are evenly distributed through the mixture.
|
|
|
Amalgams
|
Alloys that combine mercury and other metals on the periodic table.
