Answer: A. The gas particles move faster, have the same molecular composition, and have weaker attractions between them than the liquid particles.

Explanation:

Gas particles move faster than liquid particles because they have more kinetic energy and weaker attractions between themselves than liquids do. As a result of this fast movement, they frequently collide with one another and end of going even faster.

This kinetic energy that they have was gained when they were moving from liquid state to gas due to the presence of energy as temperatures increased. The temperatures gave the molecules more kinetic energy which increased their speeds as they became gas.
