Why Does a Less Dense Float

Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. … That’s because your body displaces ( moves ) the water.

Does it float if its less dense?

If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float. Density is a characteristic property of a substance and doesn’t depend on the amount of substance.

How is a dense substance able to float on a less dense substance?

An object made of a dense metal, such as a ship, can float on a less-dense substance, such as water, if The shape of the object (with a large volume) gives it an overall density less than that of the less-dense Substance. The displacement of water by a large boat results in a large buoyant force.
