If its average density is less than that of the surrounding fluid, it will float. This is because the fluid, having a higher density, contains more mass and hence more weight in the same volume. siaf torinoWebNumerous lower-density objects or substances float in higher-density fluids: oil on water, a hot-air balloon in the atmosphere, a bit of cork in wine, an iceberg in salt water, and hot wax in a “lava lamp,” to name a few. A less obvious example is mountain ranges floating on the higher-density crust and mantle beneath them. sia from the chandelier

"WebIf the object displaces an amount of water equal to its own weight, the buoyant force acting on it will be equal to gravity—and the object will float. But, if the object weighs more than the water it displaces, the buoyant force acting on it will be less than gravity, and it will sink. " - Floating objects in air
