Answer:
Chromatography is a method of separation of materials from a mixture. Paper chromatography is a technique of separation where, paper used as a stationary phase and solvent used to separate the sample used as a mobile phase. The sample is applied over the paper in small quantity. The components of the sample separates in a chromatographic paper due to the movement of solvent. The components of the sample moves with the solvent.
Paper chromatography is a useful technique for ink analysis. Ink consists of several dyes, which can be separated individually. When the ink is exposed to certain solvent mixtures the dyes of the ink dissolves in the mixture. Each ink components acquire distinct distance according to the retention factor. Some inks are water soluble, so the solvent used for separation should be water. Inks which are not water soluble are soluble in other solvents like alcohol.
Frost wedging
Explanation:
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Some agents of weathering are wind, water, glacier and gravity.
- In physical weathering, rocks are broken down mechanically into smaller bit.
- Freezing and thawing allows for the propagation of physical weathering.
- Water within cracks will expand when they freeze significantly.
- This will further expand and widen the cracks.
- When the ice thaws the stress is relieved.
- When the process continues on and on over the year, a rock will eventually break down.
- This is common around the temperate and polar regions.
