## Related Questions An object that sinks into a fluid has higher density than the fluid. The density of an object that sinks is greater than the density of the liquid in which it sinks. If an object sinks in a fluid then it has a density greater than the fluid. This assumes the object is solid and not shaped like a boat. The object's density.If less than the density of the fluid, the object floats.If more than the density of the fluid, the object sinks. If the object's density is greater than the density of the fluid you put it in, then it sinks. If less, then it floats in that fluid. yes, if its density is greater than the fluid it is immersed in, it sinks -- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.  The density of the object and the density of the fluid you drop it into. Buoyancy and pressure determine whether the object floats or sinks. An object will sink in a fluid medium if its density is greater than that of the medium. As an object sinks in a fluid the buoyant force on it would remain the same. Density will determine if an object sinks because it explains how much matter is involved per unit of volume. The object can have any density that is higher than the density of water. (Density of water: 1g/mL) It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight. Formula for Buoyant Mass m(b) m(b) = m(object) x (1- (p(fluid)/ p(object))) m(object)= true mass of the object p(object)= average density of the object p(fluid)= average density of the surrounding fluid If the fluid density is greater than the average density of the object, the object floats. If less, the object sinks. Formula for Buoyant Force: F(buoyant) = -pVg p = density of the fluid V = volume of the object being submerged g = standard gravity on Earth (~ 9.81 N/kg) Archimedes Principle: "When a solid body is partially or completely immersed in water, the apparent loss in weight will be equal to the weight of the displaced liquid." Formula for Density of immersed object relative to the density of the fluid object is immersed in: Relative Density = Weight / (Weight - Apparent Immersed Weight)  -- When the density of the stuff is less than the density of the fluid you drop it into, then it'll float in the fluid. -- When the density of the stuff is greater than the density of the fluid you drop it into, then it'll sink in the fluid. Because the density of ice is about 90% the density of sea water. A solid object sinks into a fluid until the fluid it displaces weighs the same as the entire object. That's what floating is. But if it is denser than water, it can never displace enough water to equal it's own weight, so it sinks entirely and falls to the bottom. You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.  Measure the volume of the object which is same as the volume of the displaced liquid in which that sinks. And measure the mass of the same object from a weighing machine. then use density = mass/volume Buoyancy and pressure determine whether the object floats or sinks. If an item floats, Then it is less dense than the liquid it floats in. One can prove this using bernoulli's equation. To determine the weight of the floating object, take the volume of water displaced by the portion of the object below the fliud surface then multiply that by the density of the fluid. This process gives you the bouyant force on the floating object and therefore the weight. Then take that weight and divide it by the total volume of the. Object to get its density. Also note that if an item is suspended below the surface but. Above the bottom of the fluid body, then the item and fluid have equal density. If the item sinks to the bottom it has higher density than the fluid.  If an object placed in water sinks - then it has a density greater than water.
