Explanation:
btw this is secondary school science level :
solid:
•solids have a definite shape and volume.
• they cannot be compressed
•high density
•particles vibrate in a fixed position
•high melting point
Liquid:
•no fixed shape
•partcles are free to move over eachother but are still attracted to one another
•almost incompressible
•have fixed volume but no fixed shape
•denser tagt solids
•there is space between particles
Gas:
•easy to compress
•expand to fill their containers
•particles are free to move around
•Do not have a fixed volume or shape
•gasses can diffuse- their particles move from an are of high concentration to low concentration
•low density
these are just some things of the top of my head. hope it helps
