No.
All matter has a positive mass (
Thus, any mass/volume calculations would also be positive.
Keep in mind that air near sea level has a density of between 1.2 and 1.3 kg/m3 depending on the temperature.
Some substances will have lower densities than air, for example:
The density of Helium at 1 ATM, 0°C is about 0.178 kg/m3
The density of hydrogen at 1 ATM 0°C is about 0.090 kg/m3
Thus, balloons filled with hydrogen or helium will float in air.
In space, the density is usually measured in particles / cubic meter, and is very low.
A perfect vacuum would have a density of 0.

The concentration of matter in an object?
The concentration of matter in an object is called the density.
Will a density of 2.7 float?
Is this the density of a liquid or an object? If this is the density of a liquid and you want to make an object float, than the density of the object should be less than 2.7. If this is the density of an object you are trying to make float, than the density of the liquid should be greater than 2.7.
If the density of an object is equal to the density of the fluid in which it is immersed?
If the density of an object which is equal to one(Which is also the density of the water), the object will neither sink nor float but it will be unstable, sometimes you will see the object sink then float. In other words the object is unstable in water....XD
How can you change the overall density of an object?
In a simple way, since density = mass /volume, the density of an object can be changed by changing either mass or volume of an object .
Determines if an object will float or sink in a fluid?
Density. An object will float in a substance if its density is less than the density of the substance. The density of water is 1 kg /L or 1 g/ cm3. Anything with a density less than this will float.
What factors determine how heavy an object can be and still float?
An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.An object will float if it has less density than the density of the liquid.
An object will float if?
density of the object < density of the fluid
How do things sink and float?
it depends on the density of the object and the density of the liquid that it's in. if the density of the object is greater than the density of the liquid, then the object will sink. if the density of the object is lesser than the density of the liquid, the object will float.
How can density be use to determine whether an object will float or sink in a fluid?
When you have the density of both the object and the fluid, just see which has a higher density. If the object has a higher density than the fluid, the object will sink. If the object has a lower density than the fluid, the object will float.
When you compare the density of water or air with another object how can you tell which has the lower or higher density?
-- 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.
How do you figure out density?
To find the density of an object, you have to divide the mass of the object by the volume of the object.
Whether an object will sink or float?
To know this you first need to find the density of the object and the density of the fluid on which the the object shall be kept. If the density of the fluid is more than the object's density then the object will float. The object will sink if the reverse happens.
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.
What do you need to find an object's density?
You need the object's volume and the object's mass to find the object's density. Then, you divide the object's mass by it's volume. The formula for density is d = density m = mass v = volume
What is the effect of buoyancy to the object?
The effect of buoyancy is to reduce the apparent weight of the object when it's introduced into a fluid. Depending on the density of the object compared to the density of the fluid, the object's apparent weight could be reduced to zero (beach ball floating in the pool), or even to a negative value (helium party balloon heading for the sky).
Is an object's density directly proportional to an object's volume?
An object's density is inversely proportional to the object's volume. As the volume increases the density decreases, and vice versa.
Is an object's density directly proportional to an object volume?
An object's density is inversely proportional to the object's volume. As the volume increases the density decreases, and vice versa.
