Answer
When water turns into steam, the particles move from being relatively close together to being much further apart. Thus, the correct description is that the space between the particles in steam is bigger than in water.

Answer
As water boils and turns into steam, the density decreases because steam occupies a greater volume due to increased spacing among particles. Thus, the correct description is that the density of steam is less than that of water.
