What evidence is there that marker ink is a mixture?

If you do a paper chromatography using marker ink, the result will produce different colors. This indicates the different components used in making the marker ink. Chromatography is a separation process that takes advantage of the difference of the movements of the components in a mixture.

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy
