Refimprove date April 2007 Specific properties of a substance are derived from other intrinsic and extrinsic properties or intensive and extensive properties of that substance. For example, the density of steel a specific and intrinsic property can be derived from measurements of the mass of a steel bar an extrinsic property divided by the volume of the bar another extrinsic property . Similarly, the specific gravity of a liquid is derived from the density of the liquid divided by the density of water two intrinsic properties . Uses of specific properties Reference tables Specific properties are often used in reference tables as a means of recording material data in a manner that is independent of size or mass. This allows the data to be broadly applied while keeping the table compact. Ranking, Classifying, and Comparing Specific properties are useful for making comparisons about one attribute while cancelling out the effect of variations in another attribute. For instance, steel alloys are typically stronger than aluminum alloys but are also much denser. Greater strength allows less metal to be used, which makes the choice between the two metals less than obvious. To simplify the comparison, one would compare the specific strength strength to weight ratio of the two metals. A more everyday example is grocery shopping. The two kilogram package sells for a higher price than the one kilogram package, but what matters is the specific price , commonly called the unit cost cost per kilogram . Mnemonics and Qualitative Reasoning In many instances, specific properties are more intuitive or are easier to remember than the original properties in SI or English units. For instance, it is easier ... squared. It is easy to remember that the specific gravity of water is 1.0 and that something with a higher specific gravity will sink in water.

Specific force is defined as the non gravitational force per unit mass . math mbox Specific Force frac mathrm Force non gravitational mathrm Mass math Specific force also called g force and mass specific force is measured in Metre per second squared meters second m s sup 2 sup which is the units for acceleration. Thus, specific force is not actually a force, but a type of acceleration. However, the mass specific force is not a coordinate acceleration, but rather a proper acceleration , which is the acceleration relative to free fall. Forces, specific forces, and proper acceleration s are the same in all reference frames, but coordinate accelerations are frame dependent. For free bodies, the specific force is the cause of, and a measure of, the body s proper acceleration . The g force acceleration is the same as the specific force. The acceleration of an object free falling towards the earth depends on the reference frame it disappears in the free fall frame, also called the inertial frame , but any g force acceleration will be present in all frames. This specific force is zero for freely falling objects, since gravity acting alone does not produce g forces or specific forces. Accelerometers on the surface of the Earth measure a constant 9.8 m s 2 even when they are not accelerating that is, when they do not undergo coordinate acceleration . This is because accelerometers measure the proper acceleration produced by the g force exerted by the ground gravity acting alone never produces g force or specific force . Accelerometers measure specific force proper acceleration , which is the acceleration relative to free fall, ref www.strapdownassociates.com Accels 20Measure.pdf ref , not the standard acceleration that is relative to a coordinate system.

This is sometimes referred to as unsystematic risk . In a balanced portfolio of assets there d be a spread between general market risk and risks specific to individual components of that portfolio. Determination of the extent of exposure to individual risks is made using models such as Treynor Black model Treynor Black in which the optimal share of a security is inversely proportional to the square of its specific risk. An example would be news that is specific to either one stock or a group of companies, such as the loss of a patent or a major natural disaster affecting the company s operation.

cleanup date April 2012 In thermodynamics , the specific volume of a substance is the ratio of the substance s volume to its mass. It is the reciprocal of density and is an intrinsic property of matter math v frac V m rho 1 math See also Volume thermodynamics Category Thermodynamics It is commonly applied to these cases. Specific volume is a property of materials, defined as the number of cubic meters occupied by one kilogram of a particular substance. The standard unit is the meter cubed per kilogram m 3 kg or m 3 kg 1 . Sometimes specific volume is expressed in terms of the number of cubic centimeters occupied by one gram of a substance. In this case, the unit is the centimeter cubed per gram cm 3 g or cm 3 g 1 . To convert m 3 kg to cm 3 g, multiply by 1000 conversely, multiply by 0.001. Specific volume is inversely proportional to density . If the density of a substance doubles, its specific volume, as expressed in the same base units, is cut in half. If the density drops to 1 10 its former value, the specific volume, as expressed in the same base units, increases by a factor of 10. Imagine a variable volume, airtight chamber containing a certain number of atoms of oxygen gas. Consider the following four examples If the chamber is made smaller without allowing gas in or out, the density increases and the specific volume decreases If the chamber expands without letting gas in or out, the density decreases and the specific volume increases If the size of the chamber remains constant and new atoms of gas are injected, the density increases and the specific volume decreases If the size of the chamber remains constant and some atoms are removed, the density decreases and the specific volume increases ... more details
