If an object floats it is less dense than the substance it's floating in.
yes polystyrene is ls less dence than water because it floats
Yes, That is True. eg; That has a Density Rating. a Rating for How Hard it is
ICE ... Think of a glass of water with ice cubes in it. They float! Water actually expands when it is frozen, making it less dense.
it means the liquid is heavier. It floats in the liquid.
when a object float it has density
Yes. When water freezes, it becomes less dence and floats. When warm, or room temperature, it is liquid and is more dense. This is a rare quality among substances, where most do the opposite and become more dence when they freeze.
If an object floats in water it will also float in the much denser mercury
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
i think you mean how does an object float if you did here is the answer most solids float on liquid because it has air in it (sponge) or it is lighter than the liquid.
The Density.
Color
If the object is floating, then the buoyant force is equal to the object's weight.
