The similarity between the particles in liquid water and steam at 100°C is that they are both composed of molecules of water. The difference is that in liquid water, the water molecules are closely packed together and have strong intermolecular forces, while in steam, the water molecules are far apart and have weak intermolecular forces.
The similarity between the particles in liquid water and steam at 100°C is that they both consist of water molecules. However, the difference is that the particles in liquid water are closely packed and have weaker kinetic energy, while the particles in steam are far apart and have higher kinetic energy.
