What is meant by tailing a spot in Chromatography?
Chromatography is a method of analyzing the contents of a mixed substance. It is performed by dissolving the substance in a suitable solvent. A drop or spot of the resulting liquid is deposited near the edge of a piece of absorbent paper, such as blotting paper or special chromatography paper. The strip of paper with the spot at the bottom is then suspended over a solvent with the bottom edge of the paper in the solvent. As the solvent soaks upwards, the solvent carries some particles upwards and away from the spot. Different compounds within the mixture will travel at different rates and eventually the strip of paper will show different bands of colors, separating out and indicating some of the various components that were in the original substance. 'Trailing a spot' is a short term for this laboratory process.
How do you prove that high speed wind is accompanied by reduced air pressure?
This happens because when you blow air over the paper,the air pressure above the paper reduces.The air pressure below the paper remains the same.As the pressure below the paper is greater than that above the paper it pushes the paper up.The faster the air moves ,the more is the drop in pressure in that region
What impact did invisible ink have on society?
Invisible ink was invented by Benjamin Franklin and is currently used in government documents as a secret code. Benjamin Franklin used lemon juice as the first invisible ink. The acid in the lemon juice weakens the paper where it has been spread. Therefore, if the paper is held over a candle or another heat source, the area where the lemon juice was spread will burn more easily. This will reveal the placement of the lemon juice.

What does paper contain?
The ingredients of paper are cellulose fiber (e.g. wood pulp, linen rags), water, bleaching agent, fillers (e.g. chalk), "sizing" (e.g. clay surface coating for glossiness and ink absorbency). The paper is spread on fine mesh wire screens, pressed between rollers to squeeze out excess water, and allowed to dry to remove the remaining water. Some paper also contains acids (usually from processing to make wood pulp) and if these are not neutralized the paper will turn brown and become brittle over time. The bleaching agent makes the paper white and decolorizes inks from recycled paper.
When ink flows from a fountain pen we use blotting paper remove excess of ink on the paper. why.?
Blotting helps to dry the ink faster, and the paper can be folded or turned over without smudging the writing.
