Answer:
Liquid to gas.
Explanation: Self-explanatory but the statement "As atoms gain energy, they move faster and slide past one another more easily." refers to liquid and the second statement refers to gas so therefor, its liquid to gas.
Phases of matter are the various arrangement of the molecules. The conversion of the matter is reversible. When matter gains energy, and breaks free then liquid gets converted into gas. Thus, option A is correct.
What is a change of state of matter?
The change of state of matter is the physical change that is not fixed and can be reversed back. The changes include sublimation, melting, freezing, evaporation, vaporization, condensation, etc.
The movement of the atoms and particles can vary to convert the phase of matter. The fast movement of atoms results in heat that breaks the bond of the liquid surface.
The particles of liquid start getting vaporized due to high temperature into a gaseous state. This is because the intermolecular forces in the gas are the weakest followed by liquids and solids.
Therefore, option A. liquid to gas is converted through vaporization.
