more. Less
An egg floating in salt water. The salt makes the water more dense. Since the egg is less dense it floats!
Floating and sinking is related to density - if something is more dense (i.e. has more mass per volume) than the fluid it will sink, and if it is less dense then it will float. This is why wood floats in water, and helium balloons float in air - helium is less dense than air and wood is less dense than water. Steel ships float because, although they are made of steel which is more dense than water, the air inside them is less dense than water so the overall effect is floating.
If it's in a block shape and it's floating on water,then guaranteed it's less dense than water.
Ice floats in water because it is less dense than water. A wooden boat floats on water because it is less dense than water. A balloon filled with helium gas floats in the air because it is less dense than the surrounding air. A cork floating in water floats because it is less dense than water. A rock sinks in water because it is more dense than water.
Water. The denser fats fall out of solution and sink. This makes the lower section of milk more dense and leaves the less dense water floating on top.
water's density is defined as 1g/mL. if something is more dense then it will sink due to the fact that it weighs more per volume. if something is less dense then it will float because it weighs less per volume than water. Speaking in terms of atoms, if it is more dense than the molecules are closer together and can push the water molecules out of the way (so it goes to the bottom), but less dense the water molecules push against the less dense molecules causing them to rise.

Ice is less dense than water
An example of real life density is "ice floating on water." Ice floats on water because it is less dense than water. Things that are less dense float on top of things that are more dense because molecules in ice are further apart than molecules in water.
If more dense, it will sink when put into water; if less dense it floats.
Chlorine gas is less dense than water, so it will float on top of water if the two are in contact.
More Dense.
