That is because they have no constant value; at least temperature is of great influence so it should be stated.

What are importances of specific density in foods?
every matter has its own specific density which is determine previously and a given sample is tested if its specific density varies from standard density it is a sign of adulteration in food so with the help of specific density of food we can found adulteration in food , but this method is not quiet reliable as a mixture of two substance can have same specific density as original food material but still it is used to have random check of food sample.
What are the Densities of Methane from 20-120 degrees C?
The density of methane gas at +25 degrees Celsius is 0.656 kg/m3. The density of methane liquid -90 degrees Celsius is 162 kg/m3. The SI density standard is kg/m3.
What is mass divided by unit volume called?
This is the density. ---------------------------------------- Density is an important physical and specific property of materials. Density is an intensive property irrespective on the form and dimension of the sample.
What are two factors same for the density of a pure substance to stay constant?
Density is an intrinsic property of each type of material, defined as the total mass divided by the total volume. Obviously, two samples of the material which have the same mass and same volume will have the same density, but that is not that answer to this question. This question is about the thermodynamic state of a material and the answer is temperature and pressure. The thermodynamic state of a system is a set of properties that are reproducible when the thermodynamic variables have been specified. Density is one such property. Specifying the temperature, pressure and specifying the quantity and type of material of a system determines density at equilibrium. The equilibrium condition is critically important in that assertion. It is a fundamental premise of thermodynamics that the state of a simple system at equilibrium can be completely characterized by specifying two independent property variables, such as temperature and pressure, and the quantities of the chemical constituents. Any system then with the same thermodynamic state has the same intrinsic properties such as density, heat capacity, thermal conductivity, viscosity, and other characteristics.
Comparing the density of a liquid to the density of water is?
This is the determination of the specific density (the ratio liquid density/water density).
Why you have to find average density of each liquid?
The density is a specific property of all materials; the density is very important for the technology and science.

Is density a physical or a chemical property?
Density is a physical property, specifying only mass per unit volume, but density often varies with chemical factors.
An important characteristc of urine is its specific gravity or density which is?
1.001-1.035
What are the Densities of Methane from 20-120 degrees C?
The density of methane gas at +25 degrees Celsius is 0.656 kg/m3. The density of methane liquid -90 degrees Celsius is 162 kg/m3. The SI density standard is kg/m3.
What is the purpose of conducting specific gravity test?
Specific gravity refers to the ratio of the density of a substance to the density of a reference substance. The purpose conducting specific gravity test is to determine if the test fluid will be heavier or lighter than the standard fluid.
What is relative density. What is the SI unit of relative density?
The ratio of thee density of a substance of the density of a standard , usually water for a liquid or solid and aur for a gas. The SI unit of relative density is g/ m3
The fundamental density is the ratio of the mass of a substance to its volume this is known as what?
its density. note. density is often expressed as the ratio of the density of the substance to the density of water at standard temperature and pressure. This is known as the specific gravity of the substance. It is a dimensionless number so it has no units.
What is the definition for density?
: Mathematically: :: where: :: ρ is the density, :: m is the mass, :: V is the volume. Different materials usually have different densities, so density is an important concept regarding buoyancy, metal purity and packaging. In some cases density is expressed as the dimensionless quantities specific gravity (SG) or relative density (RD), in which case it is expressed in multiples of the density of some other standard material, usually water or air/gas.
What is mass divided by unit volume called?
This is the density. ---------------------------------------- Density is an important physical and specific property of materials. Density is an intensive property irrespective on the form and dimension of the sample.
What 12 400milligrams to liter?
There can be no standard conversion. A milligram is a unit of mass. A liter is a unit of volume. For a specific substance, you can do the conversion if you know its density (mass = volume x density).
How does volume affect specific gravity?
Specific gravity is otherwise known to be "Relative Density". It is the ratio of the density of a substance to that of water as water has been taken as standard. So though volume gets changed there is no chance to get change in the relative density as it is the characteristic property of the substance.
