After a dye diffuses uniformly throughout a glass of water, the dye molecules are no longer moving. True or false?
Anton [14]
The answer is false, liquid molecules continue to move even after the concentration is uniform.

Diffusion happens because there’s a concentration gradient between the dye and the water, therefore dye molecules moves to the water area. But note that this is only the net movement of the molecules, which means, even if more molecules are moving towards water, there are still some dye molecules that are moving in the opposite direction.

So, after the concentration is equal, the motion of the dye molecules does not stop, they still move in random directions, but there’s no net movement instead, as there’s no concentration gradient. Remember molecules are always moving in all directions , it just depends on whether there’s a net movement or not. If there’s no net movement, the amount of molecules moving to each and every direction is always equal.

Deforestation is people cutting down whole forests of trees, andmaking it even less likely for humans to survive. Trees supplyoxygen, absorb carbon dioxide, and hold down the soil from washingaway or making landslides. The destruction and cutting down of forests is often done to clearland for farming, mining, roads, and grazing of cattle. That causesincreased atmospheric CO2 levels, a factor in global warming. The Cutting down and clearing of trees The action or process of clearing forests_ also _The state ofhaving been cleared by forests. Verb. To Clear of Forests or trees . The conversion of forested areas to non-forested lands. e.g. Cutting down a forest to make pastures. the cutting down of trees is called deforestation Deforestation means clearing of forests and using that land forother purposes. defforestation is cutting of trees. deforestation is when rain forests get destroyed and ruined 1.
