Because molecules will move from one side to another to come to an equilibrium, or balance of concentration, the moves from side B to side A, so the water level on side A goes .

Water, up

Explanation:

In the process of movement water in the diffusion of water the net movement of water goes from higher concentration to the low concentration area. The movement of water  move form one side to other side until it reaches an equilibrium and the level of water on the other side goes up.

Hence, the water molecule will move from from side B to side A until it reaches equilibrium and the water level on side A goes up.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
