Answer
The space between particles in steam is bigger than in water. In the gaseous state, particles have more kinetic energy and move further apart compared to the liquid state.

Answer
The density of steam is less than that of water. As particles spread further apart in steam, the overall mass per unit volume decreases, leading to lower density.
