Answer:roman one :Lie Big Condenser
roman two : Indicates when the boiling point of the medium being distilled has been reached
roman three : part A bcoz we usually say cold water in
roman 4 :Ethanol because it has a low boiling point as compared to water
roman 5 : Fractional distillation
roman 6: there are like 3 applications
a] Distillation of crude oil to obtain fractions such as petroleum,cooking gas , diesel
b]recycling of used oil
c]distillation of liquid air in the manufacture of oxygen and nitrogen
roman 7; the components have different but close boiling points
hope thizz helpsssss
