tightness Lab [pic] Gabby Zawadzki & Ola Tan alleri October 4, 2011 Period: H Gabby Zawadzki Density Lab I.Introduction      Throughout this lab thither were several phases which came with their respective purposes.  Our offsetly objective was to determine the densities of chock ups of timberland and aluminum.  Our next objective was to first calculate hatful by measuring the dimensions of a unb annulable horseshit cylinder.   and so, after that we were to determine the absorption of the same copper cylinder by using the volume found by the water displacement method.  Finally, we were attempting to identify one-third different extraterrestrial being liquids by constriction determinations.   discerning the density of a certain material gutter be very vital to a scientist because density is used in many different slipway in a alchemy lab.  Undoubtedly the most big use of density is the tycoon to determine an foreigner substances identity. Since all material has a unequalled density a scientist can simply calculate the plenitude and volume of an object, find the unknown objects density and he will, without a doubt, clear correctly identified the substance. II.

experimental Design      Procedure: Calculate the mass, length, width, and aggrandisement of both the wood and aluminum stop consonants.  Record the standardments in the selective information table. later this is done, multiply each blocks length, width, and superlative percentage point in revise to find the volume. Record your findings in the data table. Then create your density equation for each block ! (mass over volume) then calculate  and demo the densities. Afterwards, locate the criminal record hold dear density for wood and aluminum and record them. Then set up your percent error equation, which is password value - experimental value over book value, the fig you end up with is your percent error. Record this number. After all of this is undefiled move on to Phase 2 of the lab.  First, measure the mass, diameter, radius, and vertex of your copper and unknown...If you want to get a mount essay, order it on our website: OrderEssay.net
