The correct choice is **D**: The particles will have more space between them and will be moving at higher speeds as steam.
In more detail:
- **In liquid water at 100°C**: The water molecules are relatively close together, with intermolecular forces holding them in a relatively ordered arrangement, though they can still move past one another. The kinetic energy of the molecules allows them to move, but they are constrained by these intermolecular forces.
- **In steam at 100°C**: When water boils and turns into steam, the molecules are much further apart compared to the liquid state. The intermolecular forces are significantly weaker in the gaseous state, allowing the molecules to spread out. Additionally, the molecules in steam are moving faster because they have higher kinetic energy due to the heat.
Thus, at 100°C, steam consists of water vapor molecules that are more spaced out and moving at higher speeds compared to the molecules of liquid water.
