Molecules have the highest amount of energy in the gas phase because the molecules are moving faster and have more kinetic energy compared to the solid and liquid phases.
The solid phase state has the lowest kinetic energy because the particles are closely packed together and have the least amount of movement and vibrational energy compared to the liquid and gas phases.
Plasma, then 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.
In the gas phase, molecules have the highest amount of energy as they possess greater kinetic energy and move more freely compared to the solid and liquid phases.
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).
atom
The solid phase typically has the least molecular energy compared to the liquid and gas phases. In solids, molecules are close together and have minimal kinetic energy, leading to lower overall energy levels.
