What is it called when you separate liquids by boiling and condensing them at different temperatures?
Fractionation. One other specialized application is called distillation. I'd put it differently. Distillation refers to any boil and condense process. Alcoholic spirits are distilled and in many cases the idea is not to separate the components too much. Simple distillation does separate liquids at different temperatures though you would not normally refer to it as fractionation. To do fractionation effectively the cycle must be repeated many times, which can be done automatically with a fractionating column. The components that emerge in succession are called fractions.
How does normal boiling points differ from other boiling points of the same liquid?
The normal boiling point is the boiling point at sea level, or more precisely, at 1 atmosphere pressure. At higher elevations, or at lower atmospheric pressures, the boiling point is lower. At higher atmospheric pressures, the boiling point is higher.
Which has a higher boiling point 0.50 NaCl or 0.50 MgCl2?
The magnesium chloride solution has a higher boiling point.
What happens if boiling point is higher than melting point?
The boiling point is always higher than the melting point.
What relation does the boiling point of an amine have to a similar hydrocarbon?
The boiling point would be higher!
What is a process column?
A process column is a vertical cylinder in which a reaction takes place. The reaction is commonly one of filtering or selection, as measured by ionic charge; or molecular size and so on. Often an ion-exchange resin is used as the process material. A particular type of process column is the fractionating column, beloved of the petrochemical industry. These are tens of metres high, and rely on the fact that as the pressure reduces up the column, the boiling point of the (liquid) will change. Thus the high b.p material comes off lower down, and lower b.p. come off at higher levels.
How are hydrocarbon molecules separated?
using fractional distillation. first crude oil is heated up until it turned to gas and the residue (bitumen) goes through the most bottom pipe to be used for tar macing roads. The fractionating column has different fraction that are at different temperatures (gets colder as you go up). And because hydrocarbons got different boiling point (the longer the hydrocarbon, the higher the boiling point), the gas then travels up and as certain hydrocarbons got to the fraction below their boiling point they turn from gas to liquid and go through the pipe to be used.The fractional distillation goes in this order:-(shortest chain/lowest boiling point)LPGPetrolParaffinLight Gas OilDieselLubricating SubstancesBitumen(longest chain/highest boiling point)Hope this help! (if not don't blame me, I'm only 14!)

Why are fractionating towers in refineries always tall?
such towers are basically to separate the liquids having boiling points very closer (fractional distillation) so the length of the tower is useful for separation of condensing material and evaporating material, higher is the length of the tower more purity of a fraction we get.
Does chlorine or oxygen has higher boiling point?
Chlorine has higher boiling point.
Which has the higher temperature - boiling water or ice?
boiling water
Does chlorine have a higher boiling point than iodine?
iodine is having higher boiling point
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
How does salt effect boiling point?
The boiling point is higher.
What C7H16 isomer has the highest boiling point?
Heptane - longer the chain, higher the boiling point. Least amount of branches, higher the boiling point.
Which substance has higher boiling point nitrogen fluoride or NH3?
Boiling point of NH3: -33,34 0C Boiling point of NF3: -129,1 0C The boiling point of ammonia is higher.
