Here are the answers for 1(b): i) An X should be drawn inside the column at the very bottom, where the bitumen collects. This is because bitumen has the highest boiling point and highest viscosity, so it remains liquid and collects at the base of the column. ii) The fraction labelled A is kerosene. iii) The fraction with the lowest boiling point is refinery gas. iv) One use of the bitumen fraction is for road surfacing (or roofing). That's 2 down. 3 left today — send the next one.
