Detailed explanation-1: -A pure substance in the gaseous state contains more energy than in the liquid state, which in turn contains more energy than in the solid state. Particles has the highest kinetic energy when they are in the gaseous state.
Detailed explanation-2: -Answer and Explanation: Plasma possesses the most kinetic energy of the fundamental states of matter. This is because the particles in a plasma move faster than the particles in a solid, liquid or gas of the same substance.
Detailed explanation-3: -Gas particles are in constant rapid motion in random directions. The fast motion of gas particles gives them a relatively large amount of kinetic energy.
Detailed explanation-4: -A gas will only have more KE than a solid or a liquid if it is at a higher temperature. A gas has more PE than the solid or liquid phase of its own substance. So the water molecules in water vapour have more PE than they have in the liquid or the solid phase, i.e. liquid water or ice.
Detailed explanation-5: -Nitrogen and helium, at 100°C, have the highest average kinetic energy because they have the highest temperature.
