Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. … If the relative density
is exactly 1 then the densities are equal
; that is, equal volumes of the two substances have the same mass.
What does a specific gravity of 1 indicate quizlet?
The closer the specific gravity it is to 1.0grams/mL the
closer it is to be pure water
. If a solution has a higher specific gravity, what does this means? The higher the specific gravity the denser the liquid and greater the force of buoyancy will be on a object floating in/ on it (the higher it will float).
What does a specific gravity of 1 mean?
If the specific gravity is equal to one’, this means that
the object will neither sink nor float — it will hover in the liquid
.
What substance has a specific gravity of 1?
The specific gravity of a liquid is the relative weight of that liquid compared to an equal volume of
water
. The specific gravity of water is de facto 1. Liquids that are lighter than water have a specific gravity less than 1 and those heavier than water have a specific gravity greater than 1.
What does it mean if the specific gravity ratio is closer to 1?
The specific gravity of a substance is the ratio of its density to a specified reference substance. … When the specific gravity ratio for a given material is greater than 1, that means
the material will sink in the reference substance
.
What unit is specific gravity?
It has the
SI unit kg m
– 3
or kg/m
3
and is an absolute quantity. Specific gravity is the ratio of a material’s density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg m
– 3
). It is therefore a relative quantity with no units.
What is the use of specific gravity?
Specific gravity can be used
to determine if an object will sink or float on water
. The specific gravity of water is equal to one. If an object or liquid has a specific gravity greater than one, it will sink. If the specific gravity of an object or a liquid is less than one, it will float.
What is a specific gravity test?
Urine specific gravity is a
laboratory test that shows the concentration of all chemical particles in the urine
.
What is the normal range for urine specific gravity?
Normal Results
In general, normal values for specific gravity are as follows:
1.005 to 1.030
(normal specific gravity) 1.001 after drinking excessive amounts of water. More than 1.030 after avoiding fluids.
What is not required for specific gravity?
Specific gravity has no units because
it’s a ratio of density divided by density
, so all units cancel out. Therefore, the specific gravity of gold is simply 19.3. Anything with a density greater than 1,000 sinks in pure water at 4 degrees Celsius, and anything with a density less than 1,000 floats.
Which fuel has highest specific gravity?
The heavier (more specific gravity) the crude oil, the higher its C/H ratio.
Paraffins
have the highest heating value and the aromatics the least 5.4 MJ/kg. Propane higher heating value is 42.4 MJ/kg while benzene is 50.4 MJ/kg and difference is 0.8 kJ/kg (Table 2).
What is the highest specific gravity?
Osmium
has the highest Specific Gravity among minerals approved by the IMA, ice has the lowest.
What liquid has the highest specific gravity?
Fluid Temperature ( o C) Specific Gravity SG | Toluene 25 0.865 | Turpentine 25 0.871 | Water, pure 39.2 o F (4 o C) 1.000 | Water, sea 77 o F 1.025 |

Why do we test specific gravity?
A urine specific gravity test
compares the density of urine to the density of water
. This quick test can help determine how well your kidneys are diluting your urine. Urine that’s too concentrated could mean that your kidneys aren’t functioning properly or that you aren’t drinking enough water.
What are the factors affecting specific gravity?
Factors that affected USG included
age, diet type, sex, fasting status, drinking avidity, refractometer type, and the interaction between sex and diet
– increasing dietary moisture content lowered USG only in female cats. Most factors minimally affected USG.
