Relate the changes in molecular motion of particles as they change from solid to liquid to gas. As the phase changes occur, the freedom of motion of the particles

increases.

As the phase changes occur, the freedom of motion of the particles

decreases.

Eliminate

As the phase changes occur, the freedom of motion of the particles

compresses.

As the phase changes occur, the freedom of motion of the particles is

constant.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
