The SI unit for amount of substance is \\(mole\\). It has the unit symbol \\(mol\\). The mole is defined as the amount of substance that contains an equal number of elementary entities as there are atoms in 0.012kg of the isotope carbon-12. This number is called Avogadro's number and has the value \\(6.02214179(30) \\times 10^{23}\\). The only other unit of amount of substance in current use is the \\(pound-mole\\) with the symbol \\(lb-mol\\), which is sometimes used in chemical engineering in the United States.

The higher the turbidity, the higher the risk of the drinkers developing gastrointestinal diseases, especially for immune-compromised people, because contaminants like virus or bacteria can become attached to the suspended solid. The suspended solids interfere with water disinfection with chlorine because the particles act as shields for the virus and bacteria. Similarly suspended solids can protect bacteria from UV sterilisation of water. Fluids can contain suspended solid matter consisting of particles of many different sizes. While some suspended material will be large enough and heavy enough to settle rapidly to the bottom container if a liquid sample is left to stand (the settleable solids), very small particles will settle only very slowly or not at all if the sample is regularly agitated or the particles are colloidal.

The concepts of work and energy are closely tied to the concept of force because an applied force can do work on an object and cause a change in energy. Energy is defined as the ability to do work. Work is done on an object when an applied force moves it through a distance. Kinetic energy is the energy of an object in motion. The net work is equal to the change in kinetic energy." ; qudt:symbol "A" ; a qudt:QuantityKind ; rdfs:isDefinedBy ; rdfs:label "Work"@en ; skos:broader quantitykind:Energy . quantitykind:WorkFunction qudt:applicableUnit unit:AttoJ, unit:BTU_IT, unit:BTU_TH, unit:CAL_IT, unit:CAL_TH, unit:ERG, unit:EV, unit:E_h, unit:ExaJ, unit:FT-LB_F, unit:FT-PDL, unit:FemtoJ, unit:GigaEV, unit:GigaJ, unit:GigaW-HR, unit:J, unit:KiloCAL, unit:KiloEV, unit:KiloJ, unit:KiloV-A-HR, unit:KiloV-A_Reactive-HR, unit:KiloW-HR, unit:MegaEV, unit:MegaJ, unit:MegaTOE, unit:MegaV-A-HR, unit:MegaV-A_Reactive-HR, unit:MegaW-HR, unit:MilliJ, unit:PetaJ, unit:PlanckEnergy, unit:QUAD, unit:THM_EEC, unit:THM_US, unit:TOE, unit:TeraJ, unit:TeraW-HR, unit:TonEnergy, unit:V-A-HR, unit:V-A_Reactive-HR, unit:W-HR, unit:W-SEC ; qudt:hasDimensionVector qkdv:A0E0L2I0M1H0T-2D0 ; qudt:informativeReference "http://en.wikipedia.org/wiki/Work_function"^^xsd:anyURI ; qudt:isoNormativeReference "http://www.iso.org/iso/catalogue_detail?csnumber=31897"^^xsd:anyURI ; qudt:latexSymbol "\\(\\Phi\\)"^^qudt:LatexString ; qudt:plainTextDescription "\"Work Function\" is the energy difference between an electron at rest at infinity and an electron at a certain energy level.
