    Fahim Ansari 7 years, 4 months ago

    Its depends on movement of particles. Like solid particles are titly packed,so they have less kinetic energy. Liquid particles are loosely packed compare to solid and they are continously moving.so they have more kinetic energy. And same in gas , there particles are continuously moving so it have maximum kinetic energy.
