Gas (steam).
Water molecules have the highest kinetic energy in the liquid phase, as they have enough energy to move around freely but are still bound together by intermolecular forces.
If the molecules in question have a solid phase, for example water which goes from liquid to solid, namely ice, then least kinetic energy is the solid phase, with minimum kinetic occurring at 0 Kelvin (absolute zero).
When water reaches a boil, its temperature remains constant at 100 degrees Celsius until all the water has evaporated. During this phase change, the kinetic energy increases to break the intermolecular bonds holding the water molecules together. Once all the water has evaporated, the temperature will start to rise again as the kinetic energy of the water molecules increases further.
Kinetic energy
100 degrees Celsius corresponds to the boiling point of water, when water molecules have the highest average kinetic energy in the liquid state before transitioning to gas. At this temperature, the water molecules are moving the fastest, resulting in the largest average kinetic energy among temperatures below the boiling point.

in the gas phase because during this phase there is the highest temperature bc the particles are moving the fastest

Steam at 100C
The kinetic energy of water molecules in ice is less than the kinetic energy of watermolecules in water and that is less than the kinetic energy of water molecules in stream.That is because the range of temperatures where ice exists, -273C to 0C, is less than the range where water exists, 0C to 100C, which is less than the range where water gas exists, 100C and up. Kinetic energy climbs continuously with temperature through each phase.Kinetic energy is the energy of motion, KE=mv2/2.All molecules have an average kinetic energy proportional to the absolute temperature, particularly, Translational kinetic energy =3kT/2.There is no maximum. Increasing temperature increases molecular kinetic energy until the energy destroys the molecule and then the fragments will have an average kinetic energy 3kT/2.
As water is heated, the water molecules gain kinetic energy and they move faster. Eventually, they get enough kinetic energy to move fast enough to escape the liquid phase and become a gas/vapor. This is the boiling point.
By looking at the states of matter ( solid ,liquid or gas) we can determine that a giben sample will have how much energy. Molecules in solid have least kinetic energy. Molecules in vapor (gas) have highest kinetic energy. Liquids have moderatee kinetic energy.
The water has its maximum kinetic energy at the bottom of a waterfall where its velocity is highest. It has minimum gravitational energy at the top of the waterfall before it starts to fall, as it has not yet gained significant potential energy from being at a higher elevation.
When water reaches a boil, its temperature remains constant at 100 degrees Celsius until all the water has evaporated. During this phase change, the kinetic energy increases to break the intermolecular bonds holding the water molecules together. Once all the water has evaporated, the temperature will start to rise again as the kinetic energy of the water molecules increases further.
The phase of matter that has the least kinetic energy is the solid phase. You know that temperature is a measure of kinetic energy among molecules of a substance and solid is the phase of matter that occurs at the lowest temperature.
Kinetic energy
Gases spread out faster than liquids, and liquids spread out faster than solids. Gases, liquids, and solids are the three main phases of matter. A material moves to a different phase if its kinetic energy is changed enough (Kinetic energy is a measure of heat or temperature). For example, if you heat an ice cube (solid water), it will melt into water (liquid water). Gases have the highest kinetic energy. The molecules inside a gas are the fastest moving of the three phases. That means gas will spread out the fastest.
