If the density of the unknown is more than the density of water , it will sink
If the density of the unknown is less than the density of water, it will float.
Things do not float unless their densities are below that of water which is 1.00 g/ml.

What makes things float in water?
Buoyancy force is what causes things to float in water. To calculate buoyancy, use Archimedes' Principle: the buoyancy force of a submerged (or partially submerged) object is the weight of the volume of water that the object displaces. In other words, find the volume of the object that is under water, and multiply that by the density of water (1000 kg/cubic meter) and gravity (9.8 meter/sec/sec). It is also density that makes things float in water. If the object has less density than water, it will float.
Would 1.4 gmL sink or float in water?
As a general rule, anything that is more dense than the medium they are floating in will sink and things that are less dense than the medium will float. So, if you are looking into whether or not 0.85 g/ml will sink or float in water, which has a density of 1.0 g/ml, then the answer is it will float. The mechanism that will keep the object afloat is the bouancy of the medium. The force of bouancy is equal to the weight of the displaced fluid.
Why does oil float on the water?
Because the specific gravity of oil is lower than that of water. The density of water is 1 g/cm 3 and since the density of oil is less than 1 g/cm 3 it will float. if the density was more than it would sink.
What determines whether something floats or sinks?
by dividing mass by volume you get density which is how you determine as the density increases the chance of floating decreases It will remain suspended if the mass and the volume is equal It will sink if the mass weighs more than the volume and it will float if the mass weighs less than the volume
How does an object's density determine whether the object will sink or float in water?
the simple rule is that if your density is higher than the substance it will sink and if it is lower it will float density= mass divided by volume. Example:Mass 7.5g Volume:2cm3 so 7.5 Divided by 2= 3.75g/cm3 that is your density of object
Why does some things float on water while others dont?
Some objects will float on water as the density of the object is less than that of water. Conversely, if an object is more dense than the density of water, then it will sink.
What is buoyancy and how is it affected by density?
Buoyancy is the factor of things that float or sink. Density is related because if the object has more density than water, it will sink. But, if it has less density than water, the object will float.
Why do some things float and why do other things sink?
The object which have more density than water it sinks and which have lower density than water it floats.
What are the reason why some things float in the water?
Certain things float in water because their density is less than the density of water. If something experiences more upthrust in water than its weight(upthrust>weight) or upthrust=weight, then it floats in water.
Why do things float in salt water?
It's all about density.Salt water has more density than regular water. Lower density floats on higher density
Does kerosene float on water-?
no, beacuse there is more sugars patick present in it so it floats
Is it true that when the weight of an object is less than the density of water that object the object will float?
The weight does not determine if an object will float in water. If an object has a DENSITY that is more than the density of water then it will sink, if it's density is less than the density of water it will float.
How do you use the density of an object to predict whether it will float or sink in the water?
If its density is less than 1 it will float in water. If its density is more than 1, it will sink in water.
Can a egg float in cold water?
They can float in hot. Like if you boil eggs, before you set the pot, water, and eggs on the stove, you see that they don't float until the water gets warm.
Why do some things float?
They are less dense than water. More dense things sink. Density refers to how tightly the atoms are packed.
How come things sink and float?
Objects sink or float depending upon their densities. For example wood floats on water because the density of wood is less than that of water, while a piece of iron would sink in water as its density is more than water.
How does density determine if a object will sink or float?
If it is in water, the density for water is 1. If the object is less than 1, it will float. If it is more than more, it will sink. To find the density, you do mass divided by volume.
