Average kinetic energy in gas and liquid?

The average kinetic energy of particles in a gas is generally higher than that in a liquid due to the greater freedom of movement and higher thermal energy in gases. In a gas, particles move rapidly and collide frequently, leading to higher kinetic energy. In contrast, liquid particles are closer together and move more slowly, resulting in lower average kinetic energy. This difference in kinetic energy contributes to the distinct physical properties of gases and liquids, such as density and viscosity.
