Is it possible for the same object to float in one fluid and sink in another?
How can something float in one fluid but not in another fluid? A: An object will float in a fluid if its average density is less than that of the fluid. An ice cube will float in water but will sink in ethanol; ice is only a tiny bit less dense than water, and the ethanol is less dense still.
Why do some solids float on water while other sink?
Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. Hollow things often float too as air is less dense than water. When an object floats, it pushes water out of the way ( displacement ).
Do objects with the same mass float or sink in the same position?
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in….
Object | Density (g/cm3) | Sink or Float |

Will every solid with the same dimensions have the same density?
1 Expert Answer Density is defined as mass per unit volume. In other words, you take the mass divided by the volume (its dimensions). This means that if two objects have the same dimensions, but different masses, they will have different densities.
How can two objects with the same mass have different density?
Density is defined as mass per unit volume. In other words, you take the mass divided by the volume (its dimensions). This means that if two objects have the same dimensions, but different masses, they will have different densities.
How can 2 objects with different masses and volumes have the same density?
Density can change based on temperature and in some cases pressure. But all other things being equal, if you get two samples, one with double the mass of the other, it is also likely to have double the volume, so the density (the ratio of the two) remains the same.
What happens when object has same density as water?
What happens if the object has the same density as the fluid? If an object has the same density as the fluid, then the buoyant force will be equal to the gravitational force and the object will not be pushed up or down. It will remain in whatever position in the fluid it is released from.
What happens if two objects have the same density but different sizes?
Originally Answered: If there are two objects that have the same density but is different in sizes, which one is more likely to float on water, the bigger one or the smaller one? Well, it depends on what the water’s doing, and how small you’re talking.
Does bouyancy equal the weight of the displaced liquid?
Yes, you’ve answered your own question that bouyancy equals the weight of the displaced liquid. In the case of something that sinks, it’s the volume of the object because the entire object is submerged. For a floating object, the volume of the liquid displaced is that of the submerged portion of the object, such as the underwater part of a ship.
How does buoyancy depend on density of water?
The weight of water it displaces (which = the buoyancy) is the same as its weight. In a denser fluid, less of the object is in the fluid (it displaces a smaller volume which still weighs as much as it does). If an object is displacing more that this, it moves upwards, if less it falls downwards.
How much does a solid of density 5000 kgm3 weigh in air?
A solid of density 5000 kg m-3 weighs 0.5 kgf in air. It is completely immersed in water of density 1000 kg m-3. Calculate the apparent weight of the solid in water. Two spheres A and B, each of volume 100 cm3 are placed on water (density = 1.0 g cm-3).
