Why does specific heat has the same numerical value in metric and british systems?
Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.
How do you calculate volume with specific gravity and mass?
An abstract, esoteric mathematical operation known as "division." Divide mass by density, and you get volume. A note for purists: Technically speaking, specific gravity is not density, it is a ratio of densities. However, since one of the materials in the ratio is water, and its density is well known, it's easy to calculate the density of a material from its specific gravity.
What is the ratio of Two triangles that are similar and have a ratio of similarity of 310 what is the ratio of their areas?
If the ratio of similarity is 310, then the ratio of their area is 96100.
What is eqivalent ratio?
an eqivalent ratio is an ratio that is equal or you can simplfiy it
What affects the angle of refraction?
The angle of incidence.The difference in the optical densities of the media.
What are the Ratio of densities?
It is called relative density. If the second substance is pure water (at normal temperature and pressure) then the ratio is the specific gravity.
What is the importance of knowing the densities of substance?
All matter has density, which is the ratio of an objectâ??s mass to its volume. Knowing the densities of substances will help to better understand the concepts involved in buoyancy, radiation shielding, heat insulation and ballast.
What are some examples of physical quantities that do not have units?
This often happens if you take the ratio of two quantities. In that case, the units disappear. For example:* A coefficient of friction, defined as the ratio between two forces * The specific gravity, defined as a ratio between two densities
Which has the higher density one bushel of apples or ten bushels of apples?
That would be a trick question. Their densities would be the same, since density is not a measurement of volume, but a ratio involving volume.
What does density tell you about salt water?
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
How many pounds in 1L?
Pounds measure weight, and liters measure volume, so they do not have a fixed ratio. You need to know what liquid you are measuring, as different liquids have different weights and densities.
Why specific gravity has no unit or dimensionless?
Because it's the ratio of two densities ... the density of the substance of interest to the density of water. In any ratio, the units of both quantities are the same, so the ratio winds up being a dimensionless number.
What is agricultural productivity?
It is measured as the ratio of agricultural outputs to agricultural inputs. While individual products are usually measured by weight, their varying densities make measuring overall agricultural output difficult.
What is the meaning of suspicious densities?
suspicious densities are seen in both upper lobe
What is relative densities?
Relative density is the ratio of the density of a substance to the density of a given reference material.If a substance's relative density is less than one then it is less dense than the reference; if greater than 1 then it is denser than the reference. If the relative density is exactly 1 then the densities are equal
Why does specific heat has the same numerical value in metric and british systems?
Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.
Names of the five elements with the highest densities?
The five elements with the highest densities are osmium, iridium, platinum, rhenium, and neptunium.
