a. What is the trend in boiling point of the fractions?
The higher in the column, the lower the boiling point. This is because fractions which are located in higher place have small molecules (structure)
b. Define viscosity (source your definition)
Viscosity describes how well the liquid flows. E.g Water and ethanol have high viscosity. Honey has low (REMEMBER THE "SLOW") viscosity
c. What is the trend in viscosity of the fractions?
Viscosity of the fractions gets lower as it goes down the column
d. What is the trend in colour of the fractions?
The lower in the column, the darker
e. Why is crude oil separated into fractions?
Because each fractions have different boiling points
f. What process is used to separate crude oil into fractions?
Fractional distillation is used to seperate the crude oil into different fractions
g. What physical property allows this process to work?
Different boiling points for each fractions
