Answer
In steam, the space between particles is greater than in water. This is due to the increased kinetic energy of the particles in steam, which moves them further apart compared to the more closely packed arrangement of particles in liquid water.

Answer
The density of steam is less than that of water. As the water transitions to steam, it occupies a larger volume while the mass remains the same, resulting in a lower density.
