Gas
Entropy - symbol S is a measure of randomness or disorder of particles. Gases have the highest disorder or randomness and hence the highest entropy.

entropy is greater the more possible arrangements for energy there are, which increases as the molecules become more mobile, so entropy is high in a gas, lower in a liquid, and lowest in a solid.

Vapors always have more entropy than liquids of the same substance at the same temperature, because the number of energy states accessible to molecules in the vapor phase is much greater than in the liquid phase.
Entropy is a measure of the disorder or randomness in a system. The phase of matter with the highest entropy is generally considered to be the gas phase, as the particles in a gas have the highest degree of freedom and randomness compared to liquids and solids.
The transition of water (or of anything) from the liquid phase to the gas phase does constitute an increase in entropy.
The gas phase. That is true of any substance. Gases, because they are free to move about the entire volume of any container have much more entropy than either liquid or solids (and liquids have more than solids). The more ways the atoms are free to move around, the more entropy they have.

I2
the gas phase
Increasing the temperature increases the atmospheric partial pressure of the gas, shifting the equilibrium towards the gas phase. This reduces the concentration of gas in a solution as the gas molecules move into the gas phase.
This is called entropy.
