vapour/steam
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).
Gas (steam).
The molecules of a hot gas have the most kinetic energy. The molecules of a hot solid will contain the most energy per volume.
The kinetic energy of the molecules is greatest in gases.
Kinetic energy does not depend upon the phase of matter; it depends upon the amount of matter, and the speed with which it is moving. One pound of matter, whether gas, liquid, or solid, moving at a specific speed, has the same kinetic energy.

The kinetic energy is lowest in solids, higher in liquids, and highest in gases.
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.
Particles of matter have their least kinetic energy in the solid phase and their greatest kinetic energy in the gas phase.
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.
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.
average kinetic energy of molecules is roughly equivilant to temperature. as water reaches boiling point the temperature stops increasing. Instead the energy your putting in makes a phase change from liquid to gas.
The kinetic energy of the molecules is greatest in gases.
