B) Fill in the gaps with the terms you hear.
The hydrocarbons with low boiling points begin ---- ---- immediately. They are ----. So, it is safely not to heat with ---- ---- ----. As the ---- rises, it is in the side arm where it cools and ----. This happens at about 40 degrees Celsius. The hydrocarbons, which boil at this temperature, ---- ---- the side arm and form the first fraction. It is ---- ---- ----. The temperature stays at around 40 until all the hydrocarbons with this boiling point are vaporized.
