Objects with tightly packed molecules are denser than those where the molecules are spread out. (Their molecules are closer together than water molecules are.) Molecules in water are loosely placed, thereby giving the water its fluidity, while on the other hand, the molecules that fill up solids are very tightly packed, leading to the concreteness of solid objects like a rock. Similar to water, an object floats in the air when it is less heavy than air, causes enough displacement of air to make room for its surface, and maintains buoyancy. _______ means the action of an object when it becomes submerged in a liquid or fall to the bottom of a liquid.
