Abstract The purpose of this experiment was to identify whether density is an extensive or intensive physical property. By using water displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper

Precision‚ Accuracy‚ and Density Measurements This experience is intended to introduce the proper use of the most used laboratory equipments and glasswear that is come upon in the lab. As well‚ to determine the mass‚ volume and density of water by using various types of measuring glasswear‚ such as beakers‚ graduated cylinder‚ pipet‚ etc... The measurement of the density of water will determine the precision and accuracy of these measuring glasswear. Also‚ there will be a density calibration graph‚ used

Population ecology is the branch of ecology that studies the structure and dynamics of populations. In population ecology a population is a group of individuals of the same species inhabiting the same area. In contrast to genetics‚ where the population is a group of interbreeding individuals of the same species‚ which is isolated from other groups and in human demography‚ the population is the set of humans in a given area. Population density is a common biological measurement and is often used

Title: Density‚ Alcohol Content and the Archimedes Principle (Performed 09/11/13) Report submitted by: Purpose: Part I was to examine three different objects of the same material in order to identify the type of metal. We used the water displacement method and the buoyancy method according to Archimedes Principle. Part II was to find the density of ethanol by mass. We used a 25.0mL graduated cylinder and a 25.00mL volumetric flask to measure the volume. We used two different pieces of glassware

2014 Period 4 Lab #1: Density Determinations for Solutions Theory: The density of a sample of matter is very useful when trying to find the identity of an unknown substance. The units of density are quoted in (g/mL) for liquid samples of matter. For that reason if the volume is known of a liquid‚ determining its density is easily determined by weighing it accurately. Density can also be used as a tool for finding the concentration of solutions in some cases. The density is different in a substance

Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same

The word “Population Growth” has its origin from the latin words ‘Populus’ meaning people. According to ecological term; “population is group of people of the same species occupying a particular space”. Population is subdivided further into demes or local population which is group of interbreeding organism in demes; they share a common gene pool. Population density is defined as a number of individual per unit area or per unit volume of environment. When the size of the individual is uniform the

EXPERIMENT-1 DENSITY OF LIQUIDS PREPARED BY BURAK COBAN PURPOSE: In this experiment we will learn how can we find the density of liquids and liquids of density how change effect of temperature‚ pressure‚ mass‚ volume and concentration. For this reason we will take NaCI solutions with different concentrations and we will measure their densities‚ so we will find out the effects of concentration on density of solutions. THEORY: Density is a physical property
