are density and unit weight the same?

When you talk of density you are relating an object to its quantity of mass per unit volume. ... Specific weight or unit weight is the weight of a substance per unit volume of material such as water at earth gravity at 5 degress centigrade is 9.807 kN/m.

Mass density is mass per unit volume - water's is 1 kg/m3. Weight density is weight per unit volume - water's is 62.4 lb/ft3. ... The water pressure is the same one meter below the surface of any water.

I guess there is no relationship between weight and density because weight is the force exerted on an object by earth and density of an object is the ratio of its mass and volume. Unit of weight is Newton and that of density is Kg/m^3. Both are distinct.

What is the difference between density and specific gravity? Density is the relations hip of a substance's mass to its volume and has specific units whereas specific gravity refers to the comparison of a substance's density with that of water's and has no specific units.

density is simly mass per unit volume of a body,where as specific weight is the weight per unit volume of a body. ... A body will have same density in moon and earth, but will have different specific weights.

Density measures the amount of mass per unit of volume in a substance. Concentration describes the amount of a substance dissolved in another substance. Changing the concentration of a solution changes the density of the solution.

DENSITY is a physical property of matter, as each element and compound has a unique density associated with it. Density defined in a qualitative manner as the measure of the relative "heaviness" of objects with a constant volume.

Both pound and kilogram are units of measurement of weight or mass. A pound is an imperial unit of mass or weight. ... A kilogram (kg) is stated to be 2.2 times heavier than a pound (represented as lbs). Thus, one kilo of mass is equal to 2.26lbs.

Mass density is related to heaviness or lightness of an object. Usually, when we refer to density we mean a mass density which would be mass per unit volume. ... Optical density is related to the speed of light.

Bulk unit weight is the weight including both water filled voids and air pockets and of course all the mineral and organic mass. Saturated unit weight is measured when all the air pockets are filled with water 100%.

The mathematical equation is D = M / V. Density is equal to the mass, whether in grams, pounds or another unit, divided by the volume that mass occupies.

When used as nouns, density means a measure of the mass of matter contained by a unit volume, whereas thickness means the property of being thick (in dimension). Density as a noun (physics): A measure of the mass of matter contained by a unit volume.

Density is directly related to the mass and the volume. In fact it, tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.

Density is the mass of an object divided by its volume. Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).

In summary, density and specific gravity are properties used to help identify minerals. Density is a measure of the mass of a certain volume of the sample. Specific gravity is a unitless measure, and it is the ratio of the mass of a substance to the mass of an equal volume of water.

Density and mass are compleatly different. They are related as. Mass is the matter which is filled up in a body, whereas density determines what mass is filled in the body per unit volume. ... Mass is the matter which is filled up in a body, whereas density determines what mass is filled in the body per unit volume.

Most recent answer. Bulk density of any material is the weight of PARTIALLY COMPACTED material per unit volume. Bulk density of material is not equal to it's specific gravity as specific gravity is weight of FULLY COMPACTED material per unit volume.
