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 is in its liquid state, and when it boils, it transforms into steam (water vapor). In the gaseous state (steam), the particles are much farther apart than in the liquid state, which allows them to move freely and independently. Additionally, the kinetic energy of the particles in steam is greater, resulting in faster movement compared to the liquid state.
