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.
What else can I help you with?
Why can two objects with the same mass and volume have the same density?
the volume could be different that could lead to the same density. For example: d=m/v so you would have a mass of 10 for compound A and a mass of 5 for compound B, and the volume of compound A is 2 and the volume of compound B has a volume of 1. Therefore both densities equal 5.
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.
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.
What is mass divided by its volume?
Any extensive quantity divided by volume is called that quantity density .A baby's mass is small, a baby's volume is small ; but its average mass density (mass divided by volume) is the same as for anyone - anyone composed of the same materials, in the same fractions.
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?
the volume could be different that could lead to the same density. For example: d=m/v so you would have a mass of 10 for compound A and a mass of 5 for compound B, and the volume of compound A is 2 and the volume of compound B has a volume of 1. Therefore both densities equal 5.
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.
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.
If density increases and mass stays the same then what happens to the volume?
the density increases
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 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.
