States of matter
Transcript of States of matter
-Matter is an object that takes up space and has mass
States of Matter
There is space between the atoms
of a liquid and they move slightly
all of the time.
Liquids fill the shape of any container they are in.
Gases have volume and fill up space.
Space is between the gases and atoms, so that it can move around very quickly.
When liquid turns to gas, the molecules spread out and become less dense.
In solids, the molecules appear to be still,
but they are actually moving very slowly
Solids are more dense than liquids
Plasma does not hold it's shape and can be made out of electricity or electrical charges.
Plasma is found in stars and on the sun
Plasma is also found in flames, fire lightning, and polar auroras
All matter is made of atoms, which are made of small particles of matter.
Matter is an object that takes up space and has mass.
The states of matter are solid, liquid, gas and plasma. Plasma is the only state not found on Earth.
The molecules in each state move at different rates due to it's form.
The density of matter depends on how tight the atoms are.
Phase changes occur when one state of matter becomes another (solid to liquid, liquid to gas liquid to solid)
