STATES OF MATTER


Matter is any substance in the universe, from the smalles dust to the largest planet.It has mass and takes up space.It can exist in the form of solid, liqued or    
    gas.



solid
SOLID
   If a solid is put into containers of different shapes, the solid does not take the    
  shape of the containers.This shows that solid has fixed shape.Solid can be   
  weighed using a triple beam balance. This shows that solid has mass.


liquid
LIQUID

 The size of a solid cannot be changed if you squeeze it. You cannot squeeze a big 
 solid into a small container.This shows that solid has fixed volume.When water is 
 poured into various containers of different shapes, it will take up the shape of the 
 containers.This shows that liquid does not have fixed shape.


gas
GAS
 Most gases cannot be seen.They occupy space and have mass.An inflated balloon   
 shows that air occupies space.Gas has no fixed shape.The shape of gas depends on 
 the shape of the container.
