If it is more dense than water, like gold or iron or Mercury or granite, it will sink. If it is less dense than water, like styrofoam, oil or coconuts, it will float.

The density of water is very very close to 1 gram per millilitre, or 1 kilogram per litre.

Out of interest, ships float becasue they have a lower density than water. Although they are iron, the air within the ships hull makes them less dense than water.

no they dont float like normal people


How can you predict whether an object will float or sink in a fluid?

Measure the mass and volume of both to determine each's density (mass/volume). If the object is less dense; it will float, if it is mroe dense; it will sink.


Does the shape of a sustance determine if it will sink or float?

no the shape of a substance does not determine if it will sink or float. The density of the substance determines if it will sink or float. If the object weighs more than 1.0 g it will sink. If it weighs less than 1.0 g it will float.


Does mass determine whether an object will float or sink?

The density of the object (mass/volume) compared to the density of the liquid.


Hoe does an objects density determine whether the object will sink?

If an objects density is less than the density of what it is put in it will float. If the objects density is greater it will sink.


How can you determine if something will float or sink?

the volume of the instrument


How can you use density to determine whether an object wil float or sink in a fluid?

If the density of the object is less than the density of the water it is placed in, the object will float and vice versa.


How does the relative density of objects determine whether objects float or sink in liquids?

If the density of the object is greater than that of the liquid then it will sink. If the density of the object is lower it will float. To calculate density; density=mass(g)/volume(cm3)


Will kilogram float in water why?

The mass of an object alone is not enough to determine whether it will float in water. You need to know the object's mass and its volume; in other words, its density. A kilogram of solid lead will sink in water. A kilogram of styrofoam will float. If an object is less dense than water it will float; if it is denser it will sink.


Can you use volume alone predict whether an object will sink or float?

No, because you can predict if an object will sink or float mostly on density.


How can you use density to determine if an object will sink or float a fluid?

If the density of an object is lower than water then it will float, if the density is higher it will sink.


What determines whether an object will sink or float in fluid?
