After a dye diffuses uniformly throughout a glass of water, the dye molecules are no longer moving. True or false?

Biology

Anton [14]2 years ago

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.

What happens when molten material is heated from Earth’s core?
Maslowich

Correct answer: Magnetic field is created when molten material is heated from earth's core.

Due to the movement of molten iron and nickel inside the core of the earth magnetic field is generated. Due the the generation of high temperature all the molten material are in the liquid form. A Coriolis force is generated due to flow of molten liquid, which result in the formation of magnetic field.

The magnetic field of the earth is used to protect the earth from the harmful  solar radiation .
