Answer
The space between particles in steam is bigger than in water. As water heats up and transitions to steam, the particles move farther apart due to increased energy, leading to a gas state.

Answer
The density of steam is less than water. This is because the increased distance between particles in steam results in a lower mass per unit volume compared to liquid water.
