*Science!
Lets do Solids first!!!!!!!!
*
Solid- particles arranged
such that their shape are
relatively stable. An
example of a solid can be in
the form of an object such
as butter, concrete, or
glass.As you can see on one
of these pictures that if you
have a certain kind of solid
for example ice: if you
leave it for a bit then it will
start to melt and turn into
a liquid and if you put it in
a freezer for a bit it will
come back as a solid.
Liquid is one of the three primary states of matter, with the others being solid and gas. A liquid is a fluid. Unlike a solid, the molecules in a liquid have a much greater freedom to move. The forces that bind the molecules together in a solid are only temporary in a liquid, allowing a liquid to flow while a solid remains rigid.

You can have loads of kinds
of gases. You can have the
following………
atmosphere, noble
gases, helium,neon,argon,kr
ypton,xenon
Gas is one of the three
classical states of
matter, the others being
liquid and solid .Near
absolute zero, a substance
exists as a solid . As heat is
added to this substance it
melts into a liquid at its
melting point, boils into a
gas at its boiling point, and
if heated high enough would
enter a plasma state in
which the electrons are so
energized that they leave
their parent atoms from
within the gas.
Question time!
* Why does it rain?
Warm air turns the water from rivers, lakes, and oceans into water vapour that rises into the air. That water vapour forms clouds, which contain small drops of water or ice crystals (depending on how high the cloud is and how cold it is).
As clouds rise higher and higher, the air gets colder and colder. When the water vapour in the cloud becomes too heavy, it falls back to the ground as rain or snow.
BOILING
Boiling food is the process of cooking
it in a boiling liquid, usually water.
Boiling water has a temperature of
212°, and no matter how long it boils
or how hard it boils, it never becomes
hotter; for at that point it is
transformed by the heat into
steam, and in time boils away.
FREEZING
Freezing is when you put something in
the freezer and it will change: for
example, if you put a liquid in the
freezer it will turn a solid and the
same for many, many more which will
do the same.
