Describe the difference in boiling point, colour and viscosity between the fuel oil and gasoline fractions.
The fuel oil fraction has a higher boiling point. It is also dark brown in colour while the gasoline fraction is yellow. It is also more viscous (thicker and flows less easily) due to the fuel oil molecules being larger and the chains being longer.
