a. What is the trend in boiling point of the fractions?
Each fraction has a different boiling point and has you go up the fractionating column the temperature goes from high to low.
b. Define viscosity?
The state of being thick, sticky, and semifluid in consistency because of internal friction.
c. What is the trend in viscosity of the fractions?
The viscosity becomes thicker as you go down the fractional column for each fraction.
d. What is the trend in colour of the fractions?
The fractions are range from dark to light as you go up the column.
e. Why is crude oil separated into fractions?
Crude oil is separated into fractions so that it could be used.
f. What process is used to separate crude oil into fractions?
Fractional distillation is used to separate crude oil.
g. What physical property allows this process to work?
The fact that each fraction has a their own boiling point.
