States of Matter - Plasma
solid and gas are the most common states of matter on Earth.
However, much of the matter of universe is in the form of
hot plasma. Therefore reference is sometimes made to the 4
states of matter. Plasma is a state of matter, similar to gas,
in which a certain portion of the particles are ionized.
Ionization is the formation of, or separation into, ions by
heat, electrical discharge, radiation, or chemical reaction.
States of Matter - The 4 states of matter
states of matter are therefore:
- Gas - A Gas is a state of matter has no definite shape or volume (A gas
will expand to fill a container)
- Solid - A Solid is a state of matter that has its own definite shape and
- Liquid - A Liquid is a state of matter that has a definite volume (a
liquid will take the shape of a container)
- Plasma - Plasma is a state of matter similar to gas in which a certain
portion of the particles are ionized
States of Matter - Changes to the states of matter
elements are solids, only 11 are gases and 2 are liquids.
Changes, such as pressure and temperature, can alter the States
of Matter (Physical States) of an element and can determine its
relative density (mass or concentration), viscosity (how well it
flows) and malleability (how easy it is to bend).
States of Matter - Physical and Chemical Properties
substances exist as solids, liquids and gases which have diverse
Chemical Properties. Matter can
undergo physical and chemical changes.
States of Matter - CompoundsO).
compound is a combination
of two or more elements. A lot of common, everyday matter,
occurs as mixtures which are combinations of two or more
the compound we know as water 2 atoms of Hydrogen combines with
1 atom of oxygen (H2
States of Matter - Phase Changes
phase or state of matter can change when the temperature
changes, these are called Phase
Changes. For example, when a solid melts and becomes a liquid,
it goes through a phase change in which the state of matter, or
substance, has been altered. Changes in temperature to water can
change it from a liquid (water) to a solid (ice) to a gas (water
vapour / steam).
States of Matter - Chemical Formulas
reactions convert one chemical substance into another. A
Chemical formula is a type of
shorthand for representing the elements in a compound.
example, the chemical formula for water is H2
