a. What is the trend in boiling point of the fractions?
As we go down the fractionating column the boiling point becomes higher due to the molecules getting bigger, which also is why the when we go down the fractionating column the oils get more viscous.
b. Define viscosity (source your definition)
The ability of a liquid to flow, for example water has low viscosity and honey has high viscosity

c. What is the trend in viscosity of the fractions?
The Lower we go down the fractionating column the higher the viscosity of oil is
d. What is the trend in colour of the fractions?
The lower we go down the fractionating column the darker and thicker the color gets
e. Why is crude oil separated into fractions?
in order to make it useful (by using every level of oil it contains)
f. What process is used to separate crude oil into fractions?
Fractional Distillation
g. What physical property allows this process to work?
Different fractions have different boiling points.
