a. What is the trend in boiling point of the fractions?
The boiling point goes higher as the fractionating column goes down
b. Define viscosity (source your definition)
resistance of a liquid to sheer forces (and hence to flow)
/ ability for liquid to flow

c. What is the trend in viscosity of the fractions?
The viscosity gets higher as the fractionating column goes down
d. What is the trend in colour of the fractions?
The colour gets darker as the fractionating column goes down
e. Why is crude oil separated into fractions?
Because crude oil by itself is useless because it's a mixture so needs to be separated to fractions to be
more useful
f. What process is used to separate crude oil into fractions?
Fractional Distillation
g. What physical property allows this process to work?
Difference in boiling points
