Absolute versus relative densityDensity is mass per unit volume. To determine an object's density (absolute), simply divide its mass by its volume. For example, 1000 kilograms of water occupies one cubic meter. We can therefore say that water's density is 1000 kilograms per cubic meter (kg/m3), which equals one kilogram per liter (kg/L), which also equals one gram per milliliter (g/mL).

Now, let's say you have some other substance that also occupies one cubic meter but weighs 2000 kilograms. It has a density of 2000 kg/m3. In other words, relative to water, the substance is twice as dense as water. Now you have an idea of what relative density is.

If we use water as a reference, we can compare other substances' densities to the density of water. Simply divide the substance's absolute density by the absolute density of water to get the relative density of the substance (relative to water). Relative density is a unit-less quantity; it is just a number. If a substance is denser than water, its relative density will be greater than one. If it's less dense than water, it will have a relative density less than one.

Relative density is also known as Specific Gravity.

What is the difference density and relative density?

DENSITY : density is the ratio of mass and volume of the substance density=mass/volume RELATIVE DENSITY : It is the ratio of density of a substance to the density of water


Will wood float on water?

It depends on the relative density of the wood versus the water. In general, yes.


What is the difference between relative density and density?

Nothing really. Density is stated by a material's kilograms per liter relative to pure water which is used to define a density of 1.


What is the difference between relative density and density, and how do they relate to each other?

Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of another substance, usually water. Relative density is also known as specific gravity. The relationship between relative density and density is that relative density is a comparison of densities, while density is an absolute measure of mass per unit volume.


What is the difference of relative density and density?

Density is a measure of how much mass is contained in a given volume of a substance, while relative density compares the density of a substance to the density of a reference substance (usually water). Relative density is dimensionless and is often used to identify substances or determine their purity based on their comparison to a standard substance.


What is the difference between density and relative density?

Density: the ratio mass/volume for a material, expressed in kg/m3 (SI). Relative density: the ratio between the density of a material and the density of pure water at the same temperature.


How do you calculate the relative density of a substance?

To calculate the relative density of a substance, you divide the density of the substance by the density of water. The formula is: Relative Density Density of Substance / Density of Water. The relative density is a measure of how dense a substance is compared to water.


What is the Relationship between relative density and density?

the relation between relative density and density is that relative density of a substance is its density itself without its unit.


How is the relative density of an object determined?

The relative density of an object is determined by comparing its density to the density of water. It is calculated by dividing the density of the object by the density of water. If the relative density is less than 1, the object will float in water; if it is greater than 1, it will sink.


How can one determine the relative density of a substance?

To determine the relative density of a substance, you can divide the density of the substance by the density of water. The relative density is also known as specific gravity and helps compare the density of a substance to that of water.


How do you find relative density of liquid?

To find the relative density of a liquid, you need to compare its density to the density of water. The formula for relative density is the density of the liquid divided by the density of water at a specific temperature. By measuring the mass of a given volume of the liquid and comparing it to the mass of an equal volume of water, you can calculate the relative density.


How is density different from relative density?

Density is a measure of how much mass is contained in a given volume of a substance, while relative density is the ratio of the density of a substance to the density of a standard substance (usually water). Relative density is a dimensionless quantity used for comparison purposes.
