A) Temperature is increasing.

B) Kinetic energy is increasing.

C) Space between molecules decreases.
Eliminate

D) Molecular attraction is decreasing.

Answer 1

Answer:

C) Space between molecules decreases.

Explanation:

Space between molecules decreases. In fact, as we move from A to B and then C, the space between the molecules increases as does the kinetic energy. The molecules are moving faster and they are spreading farther apart as he molecular attraction decreases.

Answer 2

Explanation:

The answer is space between molecules decreases.
