you stick a thermometer in the liquid
yes different liquids have different freezing temperatures
Distillation.
This depends on each material: at low temperatures liquids become solids and gases also liquids and after this solids.
These liquids have different chemical composition and structure.
At standard temperatures and pressures, most metals are not liquids (the exception is mercury).
Yes, but at different temperatures.
Not necessarily. Both liquids and gases can exist over a wide range of temperatures.
Liquids freeze at different temperatures but it is not likely that any will freeze at 100degrees C as that is the teperature at which water boils.
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
Yes but they require specific temperatures to react.
Different liquids will vaporize at different temperatures.
Liquids take the shape of the container they are in.
