For the temperature to go down, the average kinetic energy must decrease which means that the kinetic energy of the gas molecules must decrease. Since energy is neither created nor destroyed, and energy is not "lost" due to gas molecule collisions (they are elastic), then the KE must be transferred to the molecules of some other substance at a lower temperature.
The two properties of the ink components that determine their movement along the chromatography paper/fabric are:
the solubility of ink constituent in chemical solvent.
the mixture of colour constituents in the ink.
Explanation:
Chromatography is the process in which the chemicals of the mixture are separated on the basis of constituents.
Capillary action let the colors of ink separate into their constituents. When ink is subjected to solvents it gets dissolve and gets separated.
The property of ink that led to determine their movement is:
Ink is made of many dyes of different colours, pigments etc.
The chemicals that has the best solubility in the chemical will move up on the chromatography paper and fabric.
The heat transfer to thermal energy to the ice cube causes its molecules to move faster.
Hope this helped! :)
DNA is the molecule that carries the genetic code. These are found in the nucleus of cells. They copy themselves during replication when a cell divides and splits.
