We refer the state of matter to atmospheric Pressure and Temperature.

Substance A is consider common as liquid if the boiling point of A is above room temperature.

Substance B is consider common as gas if the boiling point of B is below room temperature.

A gas is already boiled, so the boiling point must be below the current temperature. A liquid has not been boiled, so the temperature must be increased in order for the liquid to boil.

because if i wouldn't be then the thing you want to boil will not boil.

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


Do all liquids have the same boiling and melting point?

No. The melting and boiling points of liquids vary considerably.


Do the different liquid have different boiling points?

Boiling point is the temperature at which the atmospheric temperature becomes equal to temperature of the liquid......hence it completly depends upon the atmospheric temperature and the temperature of the liquid.....so different liquids will have different boiling points......


In fractional distillation a mixture of liquids is separated based on their?

The separation of liquids is based on the difference of boiling points.


What can you conclude about 2 liquids with different boiling points?

These liquids can be separated by distillation.


What is the boiling point of any liquids?

Boiling points vary from liquid to liquid.


Why is a range of boiling points given for each fraction?

It is because the boiling points of liquids are affected by dissolved solvents.


Temperature in which a gas becomes a liquid?

Each gas condenses at a different temp. as for water vapor it condenses at 212F or 100C


Which two or more liquids can be separated based on their boiling points?

These liquids can be separated by fractional distillation.


What temperature will steam condense into a liquid?

That depends on what type of liquid created the steam. Obviously, different liquids have different evaporation, boiling, and melting points.


Why are many organic compounds liquid or gas at room temparature?

Many organic compounds have low melting points and low boiling points. As a result, they are liquids or gases at room temperature.


What types of mixture do fractional distillation separate?

for mixtures that are miscible but have different boiling points
