Do all liquids boil?
No. There are liquids that boil at a few degrees above absolute zero (helium for example) and liquids that boil at several thousand degrees above absolute zero (tungsten for example)
Do all liquids expand when heated?
Liquids expand more than solids on heating
Why do different liquids have different viscossities?
Different liquids are made up of different types of molecules, which have different masses, different forces between them, etc.
Are boiling points of all liquids the same?
All liquids have different boiling point (BP). It's one of the must important characteristics of liquids. You can distinguish and also separate a mixture of liquids by boiling off one with a lower BP. The BP of every liquid depends upon the attractive forces among the atoms or molecules of the material such as hydrogen bonds, dipole attraction, London forces, etc....
Is it fesible to separate two liquids boiling points less than 5 degrees?
Yes. It's the principle on which fractional distillation works. As you heat the mixture, it will first start to boil at the lower of the two liquids boiling points, and that liquid will boil off while the temperature of the mixture will remain constant. After the first liquid is boiled off, the temperature of the remaining fluid will then start to rise till it reaches it's boiling point. The second liquid will then start to boil.
How would you separate liquids if two liquids boil at different temperatures?
Distillation.
Why is it possible to separate mixtures of liquids by boiling?
Different liquids boil at different temperatures. When the boiling points (the temperature at which a liquid boils) are sufficiently different, boiling can be used to seperate the liquids
What property of the fractions makes the fractional distillation works?
Because the mixed liquids have different boiling points allowing the different liquids to boil at different times!
Why do the fractions separate at different temperatures?
Because they have different chemical properties and boil at different temperatures
Why can't liquid boil at a low pressure?
Liquids can boil at low pressure, and in fact do so at lower temperatures than when the pressure is high.
Distillation can be used to separate solutions of miscible liquids because ?
Distillation works because liquids boil at different temperatures. Roughly speaking, in order to separate two liquids, you should heat the mixture to a temperature where one of the liquids (but not the other) is past its boiling temperature. Then the first liquid will boil off, leaving the second liquid behind; you can collect the first liquid in a condenser.
Why does liquids have any form?
Liquids have different forms because when they get above a certain temperature the could boil or freeze.
Are all liquids can be change to solid?
Yes, but at different temperatures.
What temperature should it be when a liquid turns to a gas?
Different liquids will vaporize at different temperatures.
What is the saturation temperature of vapour or the boiling temperature of a liquid?
Different liquids have different boiling temperatures, even the same liquid will have different boiling temperatures at varying pressures.
What are the different kinds of volatile liquids?
Liquid that has a high boiling point. A liquid that releases molecules as a vapor.
Does the type of liquid affect the time it take to freeze?
yes different liquids have different freezing temperatures
