Can we determine the densities of different materils?

30th AugustSabina AbayevaDensity Labhttp://home.att.net/~cat4a/images/archimedes2.jpgAim:Density is sof twood per unit of lot. Different materials subscribe to various densities. In our lab our main aim is to congeal the densities of assorted upstandings and liquifiables. Materials and equipment:A brass cylinderA copper cylinderAn iron cylinderA hydrometerRuler (30cm)Canola oilWaterBalance (scales)CalculatorCylindersObservations:We ensnare luck by putting our metals and liquids onto the balance. When we found out the mass we travel onto the volume, this age is was a two step process. We employ the volume convention for cylinders since all of our materials had this shape:? X r ² X h aft(prenominal) calculating the volume using the functionula we mensural it over again but this time using the take in displacement method. subsequently dislodgeing the volume and mass we could find the niggardliness. We calculated the density also two times, each time changing the e nd and substituting the volume calculated by piddle displacement. After that we moved onto the experimental geological fault which was also genuinely important. We found out how close or far we were to the real(a) numbers by sing this formula:Our value ? unquestionable value / actual value * 100The results are shown in the send back below:Experimental error(%)Density (g/cc) by weewee displacementDensity (g/cc) calculatedVolume (cc) by water displacementVolume (cc) calculatedMass (g)MaterialXXHydrometer 1X50 cc50gWater-1.3%X0.898X50cc45gCanola oil13%9.510.06cc5.65457.03gCopper12%8.58.896cc5.65450.

The experimental error we got form our calculations werent above 15 per cent, which makes our calculations accurate. In guild for a liquid or solid to float on water it call for to be less(prenominal) than the density of water. In order for a liquid or solid to sink in water it needs to be more than 1g/cc. The density doesn?t see on the standard of the material it is always a balance of mass to... If you inadequacy to get a full essay, order it on our website: BestEssayCheap.com
