If it less dense
The tendency of a solid object to float in a fluid is determined by the relationship between the density of the object and the density of the fluid. If the object is less dense than the fluid, it will float. If the object is more dense, it will sink.
An object float in a liquid only when the density of the solid is lower than the density of the liquid.
Well rocks don't float because they are a solid with no air.
It depends on the density of the object you are using
Objects less dense than air can float on air of that density. Air passing over objects (wings, kites, etc.) can provide lift and support the object. Air moving upwards at a speed equivalent to the terminal velocity of the object in the air stream will support the object. Solid air (frozen at -299oC if you don't care about the Helium or -270oC if you do) will support objects like any other solid.
no and mass is air
To determine the volume of air needed to float an object, you need to know the density of air and the weight of the object. For example, if the density of air is approximately 0.075 lb/ft³, then to float a 1000-pound object, you would need approximately 13,333.33 ft³ of air (1000 lb / 0.075 lb/ft³ = 13,333.33 ft³).
the object with float up
the object with float up
You can deduce that, if the object was in the form of of a solid "blob" it would not float on water.
Buoyant means: Tending to float on a liquid or rise in air or gas
The Object's name is an "Air Craft"If its not... Then I don't really know.
