Lets do Solids first!!!!!!!!

Page 3: Science week

*

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!

Page 9: Science week

* 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.
