SOLID LIQUID AND GASS

SOLIDS
In a solid the particles fit very closely together. They constantly twist and vibrate however they do not move past the particle beside them. Because the particles are close together:

  • They attract their neighbours - this is why solids tend to keep their own shape and stay the same shape.
  • Solids are very difficult to break or compress ; the gaps between particles are already very small.

LIQUIDS

In a liquid the particles are still close together but a little further apart than in a solid. The particles mix with other particles. Therefore, liquids can change shape to match their container. Even tough they can mix with other particles there are still little space between them, so liquids are also difficult to compress.

Gases

In gases the particles are much further apart than in solids or liquids there much more 'free'. There is a lot of space in between the particles and they are constantly moving about every once in a while bumping into each other.
