Answer:
The ice form of water is most dense, and the vapor form of water is the least dense.
Explanation:
The molecular cohesion in ice is stronger than in liquid or vapor, forcing the molecules of water to remain closely bonded making it dense. The vapor form of water is weaker that liquid and ice since the molecules are nearly free roaming or loosely bonded making it not very dense.
Cheers.
when considering the states of matter, solids are more dense than gases and liquids. Gas is least dense.
