_______________________________________________________________

Summary..

Solid

-Fixed SHAPE and VOLUME
-Hard
-High density
-Cannot be compressed

Molecules
-Closely packed together in a regular pattern
-Vibrate in fixed positions

Liquid

-Fixed volume
-No fixed shape
-High density
-Cannot be compressed

Molecules
-Not arranged in a regular pattern
-Slightly further apart, compared to solids
-Have attractive forces between the molecules thus difficult to separate from each other

Gas

-No fixed SHAPE or VOLUME
-Low density
-Compressible

Molecules
-Far apart
-Move randomly in high speed
