Why is it necessary to run TLC in a closed container and to have the interior vapor saturated wit the solvent?

It is necessary to run TLC ina closed container and have the interior saturated with the solvent vapour to ensure maximum resolution between components and to prevent solvent evapourating off. If the solvent evapourate off, the Rf value would be lower than the expected value.

When a solvent is holding the maximum amount of solute for that given temperature?
A saturated solution
What solutions one that contains as much solute as can be dissolved in the solvent?
That solution is called saturated.
What is an over saturated solutions?
When a solute cannot be dissolved further in a solvent, at a given temeperature, the solution is saturated; if this amount of solvent is exceeded the solution is oversaturated.
Why the more the volume of solvent thefaster sugar dissolves in water?
When enough sugar is dissolved into the solvent (water) , or goes 'in to solution' , that no more will dissolve , the solvent is said to be 'saturated'. The more solvent you have the more sugar you can put into solution. No more sugar will dissolve once the solvent (now your solution) is saturated.
What is the type of solution with so much solute that no more will dissolve?
When a solute is added to a solvent until no more dissolves, the solution is said to be saturated. In some cases a solution can be made to be supersaturated by temporarily increasing the solubility of the solvent, such as through an increase in temperature.
Why is it necessary to keep the beaker used for chromatography tightly covered with para film while the solvent is rising through the TLC slide?
solvent will only rise through the TLC slide only and only if the container is saturated with the vapours of the solvent.
What do you call a solution in which the maximum amount of solvent has been dissolved any more solute added will sit as crystals on the bottom of the container?
Saturated.
What is saturated salution?
A solution in which the maximum amount of solvent has been dissolved. Any more solute added will sit as crystals on the bottom of the container.

How do you know solution is saturated?
The solution is saturated when no more solute dissolves in the solvent.
How do you know when solution is saturated?
The solution is saturated when no more solute dissolves in the solvent.
How do know when a solution is saturated?
The solution is saturated when no more solute dissolves in the solvent.
What is an over saturated solutions?
When a solute cannot be dissolved further in a solvent, at a given temeperature, the solution is saturated; if this amount of solvent is exceeded the solution is oversaturated.
What is over saturated solution?
When a solute cannot be dissolved further in a solvent, at a given temeperature, the solution is saturated; if this amount of solvent is exceeded the solution is oversaturated.
What is it when a solute can't dissolve anymore into a solvent?
Saturated
