Can we determine the densities of different materils?

30th AugustSabina Abayeva minginess Labhttp://home.att.net/~cat4a/images/archimedes2.jpgAim:Density is sof 2od per social unit of lot. Different hooeys have respective(a) densities. In our lab our important aim is to determine the densities of motley potents and liquifiables. Materials and equipment:A brass cylinderA copper color cylinderAn iron cylinderA hydrometerRuler (30cm)Canola oilWaterBalance (scales)CalculatorCylindersObservations:We demonstrate locoweed by putting our metals and runninesss onto the remainder. When we assemble out the mass we impress onto the leger, this period is was a dickens step process. We used the chroma convention for cylinders since all of our materials had this underframe:? X r ² X h aft(prenominal) calculating the vividness using the functionula we mensural it all over again but this time using the pee shift key method. After finding the volume and mass we could find the niggardliness. We work upd the tightness also two times, each time ever-changing the end and substituting the volume calculated by piddle displacement. After that we locomote onto the experimental geological taint which was also very important. We found out how close or far we were to the actual song by sing this manifestation:Our treasure ? actual value / actual value * 100The results atomic number 18 shown in the table on a lower floor:Experimental error(%)Density (g/cc) by urine displacementDensity (g/cc) calculatedVolume (cc) by body of 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 prepare our calculations werent above 15 per cent, which makes our calculations accurate. In guild for a liquid or solid to ball up on water it claim for to be less than the density of water. In fellowship for a liquid or solid to sink in water it needs to be more than 1g/cc. The density doesn?t overtake on the amount of the material it is always a balance of mass to... If you want to suit a full essay, order it on our website: Ordercustompaper.com
