The similarity between the particles in liquid water at 100°C and steam at 100°C is that both consist of water molecules. The difference is that in liquid water, the molecules are closely packed together and have a fixed volume, whereas in steam, the molecules are spread out and have a greater kinetic energy.

Okay, so like, the particles in liquid water and steam are kinda the same because they're both made of water molecules, right? But the thing is, in liquid water at 100°C, the molecules are all squished together and stay in one place, so they have a set volume, like they won’t change size. But in steam at the same temperature, the molecules are all spread out and moving around a lot more, which means they have more energy. So yeah, they’re similar but kinda different too!
