It tells you the volume and the weight of the substance. eg- Q. Which weighs more? A tonne of coal or a tonne of feathers? A. They both weigh the same. It is the amount of volume it has and how much it weighs.
Density refers to the ratio of weight (or, more accurately, mass) to volume of a substance. That is: the mass of the substance per unit volume.
Mathematically:
ρ = m/V, where:
ρ (rho) is the density,m is the mass,V is the volume.
The standard unit for density is kilograms percubic metre (kg/m³)
Density is a property of a material.
It indicates how densely packed is the object. A denser material is always heavier and well packed in comparison to a less dense material.
Density is measured in units of kg/m3 (kilograms per cubic meter) in SI and g/cc (grams/cubic centimeter) in CGS. It is the ratio of the mass to the volume of the material. Density for water is considered as 1g/cc.
A substance with high density indicates that the particles are packed close to one another (e.g. solids), while substances with low densities have their particles spaced far apart since density is the measure of mass per unit volume.
It tells you how heavy it will be for its volume (density = mass / volume).
A common application of this is determining whether an object will float. If an object is less dense than the liquid it is in, it will float.
The density of a substance represents the number of grams of mass
packed into every cubic centimeter of the substance.
How heavy it is
weight of the object
density
The concentration of matter in an object is called the density.
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 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
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 .
density tells us how packed the object is
It means that the object has an equal density to the water.
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.
You can tell that it is less dense than water which has a density of 1 cc
density
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.
Yes, because density is measuring the volume of the object. So it shows how much percent of the object is submerged.
If an objects density is 1 or less, it will float on water
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
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.
To tell whether a golden object is real gold, to know if an object will float or sink on a certain water source.
