"A person can make you feel something in 2 months which someone else can't in 2 years" Cognito teaches some of the toughest concepts , which students like me can't understand, in 2 mins Meanwhile our teachers can't do it in 2 months Time doesn't matter, character does.

REMEMBER, the pencil line is drawn to prevent the ink from rising which would hide the correct results of the experiment. The solvent is below the baseline to avoid the spots from being removed off the baseline

I have a few questions 1. Does temperature affect the Rf value? Given the stationary phase, solvent, and solutes stay the same. 2. Does the Rf value stay constant with the same conditions but different baselines? 3. Why are there usually some of the solute as a trail when paper chromatography is performed 4. Does the solute eventually just stop? Or can it keep going if you leave it. If it can keep going, can the solvent front change too? Or is it always constant with the same stationary phase and solvent?
