Specific gravity and density will have the same value when the two substances under investigation have identical densities. Let's look at this. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Liquid water has a maximum density at about 4 °C. And there is 1 gram in a cubic centimeter or a milliliter of water. We say water has a density of 1 gram/cubic centimeter. Other substances can have their mass discovered when a known volume is weighed, and then the density of those substances can be discovered and recorded. Specific gravity is a comparison of the density of a substance to the density of water. The specific gravity of a material will not have units associated with it. It is a purenumber. If a substance has a spee gee (lab speak for specific gravity) of 2, it will have 2 times the density of water. A cubic centimeter of this material will weigh 2grams, and will have a density of 2 grams per cubic centimeter. But, to repeat, spee gee has no units associated with it. The only time that specific gravity and density will have the same value is when the substance under inspection has the same density of water at 4 °C. That's the only time density and spee gee will have the same value. And note that we're talking value here, and without regard to units. Density has units of mass per unit of volume, and specific gravity has only a numerical value, only magnitude, and nounits associated with it.
No, volume and density are not the same. Volume is the amount of space that an object occupies, while density is the amount of mass per unit volume of a substance. In other words, volume tells us how much space something takes up, while density tells us how much mass is concentrated in that space.
Density is expressed in Mg/m3 (or g/cm3).
Specific gravity is relative, has not unit: this is the ratio density of a liquid/density of water at a given temperature.
Density: mass / volume
Specific gravity: density, compared to the density of water. That is, divide the density by the density of water.
For example, in SI units, iron has a density of about 7900 (kilograms / cubic meter meter, and (since water has a density of 1000), a specific gravity of 7.9.
Specific gravity and density are not the same. Density is given as mass divided by volume, and specific gravity is a ratio of the density of a substance to the density of water.
Specific gravity is defined as the density of a substance, divided by the density of water.
Density is the weight per unit volume at the same temperature, where as the specific gravity is the weight of same volume of water at the same temperature.
No, imagine an equal sized block of steel, and of Styrofoam. They are both the same size, so they have the same volume, but the steel block has a higher density so it's heavier.

Why can two objects with the same mass and volume have the same density?
Density is a property that represents the compactness of a substance. If two objects have the same mass and volume, it means that they have the same amount of material packed into the same amount of space, resulting in the same density. Density is calculated by dividing mass by volume, so if mass and volume are equal, density will also be equal.
If mass stays the same and density decreases then the volume does what?
If mass stays the same and density decreases, then the volume must increase. This is because density is mass divided by volume, so if density decreases while mass remains constant, the volume must increase to maintain the same mass.
What is mass divided by its volume?
Mass divided by volume is density. Density is a measure of how much mass is contained in a given volume and is often used to characterize materials and substances. Mathematically, density is calculated as mass divided by volume (density = mass/volume).
Is it possible to have diffferent volumes yet same density?
Since Density=Volume/Mass, and the mass increases as the volume increases they will always have the same density no matter how big it is.
Why does a pool of water have the same density as a cup of water?
The density of water remains constant regardless of the volume or shape of the container it is in. This is because the mass of water and its volume stay the same, resulting in the same density for both a pool and a cup of water.
If two objects have the same volume and density do they ave the same mass?
Yes, if two objects have the same volume and density, they will have the same mass. This is because mass is calculated by multiplying density and volume; therefore, having the same density and volume means the objects will have the same mass.
Why do two samples with the same substance with the same volume HAVE to have the same mass?
Because they are of the same substance they have the same density density = mass/volume
If A sponge and a brick that are the same size they have the same what?
no; they have the same volume but their mass is quite different; density is mass/volume and the sponge has much lower density
If 2 objects have the same density what else must be the same?
If two objects have the same density, then their mass and volume must also be the same. Density is calculated by dividing an object's mass by its volume, so if the density is the same for two objects, it means that the ratio of their mass to volume is equal.
Why does mass and volume affect density?
The density of a substance is its mass divided by its volume. So for the same volume the higher the mass, the higher the density.
Why can two objects with the same mass and volume have the same density?
Density is a property that represents the compactness of a substance. If two objects have the same mass and volume, it means that they have the same amount of material packed into the same amount of space, resulting in the same density. Density is calculated by dividing mass by volume, so if mass and volume are equal, density will also be equal.
How does a change in mass or volume effect density?
If mass increases while volume stays the same, density increases. If volume increases while mass stays the same, density decreases. Density is calculated as mass divided by volume, so any change in mass or volume will affect the density of a substance.
Changing the mass or volume of an object changes its density and?
Changing the mass or volume of an object will alter its density. If mass increases and volume stays the same, density will increase. Conversely, if volume increases and mass stays the same, density will decrease.
If mass stays the same and density decreases then the volume does what?
If mass stays the same and density decreases, then the volume must increase. This is because density is mass divided by volume, so if density decreases while mass remains constant, the volume must increase to maintain the same mass.
If density increases and mass stays the same then what happens to the volume?
the density increases
If two balls have the same mass but one has larger volume which ball has the largest density?
The ball with the larger volume and the same mass will have the lower density. Density is defined as mass divided by volume, so as volume increases with constant mass, density decreases.
If the volume of an object increases what will the density do?
If the volume of the object increases while its mass remains constant, the density of the object will decrease. This is because density is calculated by dividing mass by volume, so if volume increases and mass stays the same, the resulting density will be lower.
