Gases
Solid: coming from a state of lower kinetic energy; going to a state of higher kinetic energy. Liquid: coming from a state of higher kinetic energy than solids; going to a state of lower kinetic energy. Gas: coming from a state of higher kinetic energy; going to a state of lower kinetic energy.
The physical state, or phase, that has the greatest kinetic energy is gas. In a gas, the molecules are more free to move and they move more rapidly than in the other phases, and it is this motion that constitutes kinetic energy.

The kinetic energy of molecules is directly related to their physical state. In general, molecules in a higher energy state (higher kinetic energy) tend to be in the gaseous state, where they have more freedom to move around. Conversely, molecules in a lower energy state (lower kinetic energy) tend to be in the solid or liquid state, where they have less freedom of movement.
When any substance goes from solid to liquid to gas, the kinetic energy of the molecules increases.Molecules in the gaseous state have the most kinetic energy.Molecules in the solid state have the least kinetic energy.
In the solid state, particles are tightly packed and have the least amount of kinetic energy. In the liquid state, particles are less tightly packed and have more kinetic energy than in the solid state. In the gas state, particles are far apart and have the most kinetic energy.
Kinetic energy is energy produced by motion/activity. Molecules become more active as they heat up. Therefore, molecules in a gaseous state would have the greatest kinetic energy.
A hot gas would generally have the most kinetic energy, followed by a hot liquid. This is because higher temperatures increase the average speed of the particles, leading to greater kinetic energy. Solids and cool gases/liquids would have lower kinetic energy due to the reduced movement of their particles.
