Darn it. Studying's not going well.
Let me summarise what i learnt.

Chapt 2:
- elements are made up of tiny particles.
- particles in solids are closely packed, in a fixed position and can only vibrate about their fixed positions
- Particles in liquids are further apart, can move short distances and are not arranged in a fixed position.
- Particles in gases are far apart, can move freely and occupy any available space.

Ahhh i can't do it!!!
Oh and i found the answer for "what is light".
Light is a form of energy!!! Yay!!!
Ok no more distractions.
BYYYYEEEEEE!!!!!!!!
