The correct response is: The particles will have more space between them and will be moving at higher speeds as steam.
At 100°C, water (in its liquid state) has particles that are relatively close together and moving at a moderate speed. When water boils and turns into steam at the same temperature (100°C), the particles of steam are further apart due to the gaseous state, and they generally move faster compared to the liquid state. This reflects the differences in the arrangement and movement of particles in the two states of matter.
