a. What is the trend in boiling point of the fractions?
There are longer chain molecules and the boiling point increases as you go down the fractions
b. Define viscosity (source your definition)
Viscosity Having a thick, sticky consistency between solid and liquid (en.wiktionary.org/wiki/viscous)
c. What is the trend in viscosity of the fractions?
As you go down the trend, the substances become more viscous meaning that the become more thick and sticky.
d. What is the trend in colour of the fractions?
As the boiling points get higher, the colour of their substances get darker and darker. (As shown in the image above)
e. Why is crude oil separated into fractions?
Crude oil is separated into different fractions because each of the fractions have a different use.
f. What process is used to separate crude oil into fractions?
The Process is called Fractional Distilation
g. What physical property allows this process to work?
The different boiling points
The different boiling points
