Answer:
a pH meter is the correct answer
Explanation:
i just did the test
Answer:
percolation evaporation condensation and precipitation
Explanation:
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.
Erosion is the process of eroding or being eroded by wind, water, or other natural agents. Erosion can dissolve rock, weakening it or turning it into tiny fragments. Deposition is the process by which sediments settles out of the water or wind that is carrying it, and is deposited in a new location. <span>Deposition transports previously eroded sediments, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment. </span>
