Research on Density Essay
ABSTRACT
The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined, and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since the density of an object may be found using its mass and its volume. The experiment yielded two different density values, however when error analysis was conducted, the water displacement method was proven to be more accurate.

Table 2: Measurements of Dimensions of the Given Object DIMENSION Length b Width w Height h Table 3: Initial and Final Volumes of Water INTIAL(mL) 500.0 Calculations: Volume1 = area of face of solid x width = (1/2b x h) x w = (1/2 x 10.0cm x5.0cm) x 3.5 = 87.50 cm3 Volume2 = Vf  Vi = 520.0mL 500.0mL = 20.0mL Density = Mass/Volume D = m/V D1 = m/V1 ; m=5.32g, V1=87.50cm3 FINAL(mL) 520.0 MEASUREMENT(cm) 10.0 3.5 5.0
Therefore D1= 5.32g 87.50cm3 = 0.0608 g/cm3 D2 = m/V2 ; m= 5.32g, V2= 20.00 mL Therefore D2 = 5.32g 20.00mL =0.266g/mL

The Density Of Water Density
1446 Words  6 PagesIntroduction: In this lab, we looked into the density of water. Density is defined as “…the mass per unit volume of a substance.” (“Water Density”, 2015). The equation for density isD=M/V, meaning density (D) = mass (m) ÷ volume (v). According to Mader (2013) “Water is more dense at 4°C than at 0°C. Most substances contract when they solidify, water expands when it freezes because in ice, water molecules form a lattice in which hydrogen bonds are farther apart than in liquid water.” (p.31).…

In the first activity, we were tasked with finding the density of a cylinder…

The Implications Of Density Dependence
1336 Words  6 Pagespurpose of this study is to document the implications of density dependence in crawfish frog populations in two different environments: restored prairie and disturbed farmland, to find out equilibrium population size is most sensitive to which life stage and to study whether the strength of density dependence varies with environment. We hypothesize that strength of density dependence will determine the equilibrium population size. Strength of density dependence can vary from weak to strong depending on…

The Density Den ( Experiment 4.3 )
888 Words  4 PagesThe Density Den (Experiment 4.3) Taken from Obook (aim, materials and method) Date: Monday 15th June Partners: Nicole and Grace Introduction:  When people think of Archimedes they often think of the famous tale of his bath, and how he helped discover density whilst unknowingly using the displacement method.  Density is the mass and volume of substances which is different in the 3 states of matter. The density of the 3 matters can often be affiliated with the amount of space inbetween the particles…

Measurement Of Density And Density
1428 Words  6 PagesMEASUREMENT OF DENSITY Lichang Wu Feb. 22, 2015 Abstract The purpose of the lab was to determine densities of materials. Density is the amount of matter in a given amount of space. Density is a physical property that is independent of the amount of material present. The formula for density is density=mass/volume(d=m/v). Introduction Density is a measurement of the amount of mass that have a specific volume. Density is used for identifying substances. Density is reported as g/ml…

Lab Report on Density Measurement
2170 Words  9 PagesINTRODUCTION 1.1 Background of the Experiment Mass density describes how heavy an object is. Defined by the Greek letter ρ, read as rho, density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids, density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1. The SI unit of density is kg/m3. However, its CGS units, g/cm3 or g/ mL, are the most commonly used ones in the laboratory. The…
