Separationtechnique in whichtwo or more miscibleLiquids are separatedbecauseof different Boilingpointsis called Fractional Distillation 1
Indirectheatis provided because i
i Direct heat willnotprovide uniform rise intempiil FlammableLiquids maycatch fire
Glass beads provide large surface area forthe vapoursto condense backLeipig condenser isused to convert vapoursback into Liquid
A Errors in Apparatus
4Coldwater in should be against Gravity
4Thermometer should not touchthe Glassbeads
olDistillatingapparatus shouldnot be Air Tight
