1. FiltrationANS It removes large, insoluble particles from a
liquid. eg. sand from wter
substance if
2. evaporation/crystallisationANS leaves behind crystals of a
dissolved heated gently
3. DistillationANS condesing and evaporating a solvent and then cting it
colle
ntspoi
4. Fractional distillationANS separates liquids due to their boiling
5. chromatographyANS causes a substance for rise up paper due pillary action.
to ca lighter particles move further up .
6. solidANS vibrate about fixed
positions regular lattice arrangement
cannot be compressed
7. liquidANS no regular arrangement and can move past each
1/9
, other cannot be compressed
8. gasANS particles are far
apart move randomly at fast
speeds can be compressed
9. what is needed to overcome the electrostatic forces of attraction
between the particles to melt/evaporate?ANS heat energy ng model.
10. what model of the atom did JJ Thomson designANS Plum
puddi sphere of positive mass and negative particles randomly
inside.
