a. What is the trend in boiling point of the fractions?
The higher up the column you go, the lower the boiling point
b. Define viscosity (source your definition)
The state of being thick, sticky, and semi fluid in consistency, due to internal friction http://www.google.com/search?client=safari&rls=en&q=define+viscosity&ie=UTF-8&oe=UTF-8
c. What is the trend in viscosity of the fractions?
As you go up the column the viscosity increase.
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?
Crude oil is of no use on its own.
f. What process is used to separate crude oil into fractions?
They use the fractionating column
g. What physical property allows this process to work?
The process used is heating, and the physical property are the different boiling points of the different fractions
5.9 part c. I think you got this the wrong way round!
