2) What is the main difference between a 
     lyophillic colloid and a micelle?
A lyophillic colloid is a “solvent liking” 1 phase system – the colloid is soluble in the
dispersion medium. If the dispersion medium is water the colloid will be polar
eg. protein+H2O
A micelle is an organised aggregate of highly surface active materials (surfactants).
• The micelle is insoluble in the disp. medium. The surfactants will either be polar or ionic which determines the size of the micelle.   eg. sodium stearate (<100) + H2O
