One of the physical properties of matter is density. Density is defined as a measure of how much mass is contained in a given unit volume. A physical property can be measured without changing the chemical identity of the substance. Since pure substances have unique density values, measuring the density of a substance can help identify that substance. Density is determined by dividing the mass of a substance by its volume. Density, volume, and mass have a clear relationship that can clearly be shown…

There is a strong correlation between obesity and brain performance.Being overweight or obese causes poor brain performance. When there is an excess of cholesterol in the human body, there will be delays in motor skills, memory, and constant exhaustion. Simply being overweight or obese causes all these negative effects. Being overweight or obesemeans weight numbers are greater than what is considered healthy. In other words,the higher the weight number, the higher the chance of catching a disease…

The density of water is its mass divided by its volume. In this case, the mass of water was determined by subtracting the final mass of the glassware with water by the initial mass of the glassware without water. The volume was determined by observing closely which line (marked on the sides of each glassware) the water reached and reporting the most precise measurement. Based on the class data, the average densities of water and its standard deviations were: 50-mL beaker – avg: 0.90 g/mL, stand dev:…

Abstract The purpose of this experiment is to find a correlation between a solution’s salt concentration and its density. The objectives are: First review use of electronic balance. Next learn to calibrate the glassware. Than learn to use a volumetric flask. After that learn how to determine density. Finally learn how to calculate percent error. It is known that density equals mass divided by volume which is a simple formula that gives half of the desired information. The equipment that was used…

determine whether boiling point, density, mass, and volume are intensive or extensive properties two experiments will be conducted. One experiment will be dedicated to identify if boiling point is an intensive or extensive property by boiling water at different quantities. The other experiment will identify if density and mass are intensive or extensive properties by utilizing a grape. The experiment will consist of measuring the mass and volume of a grape to determine the density. Both of these experiments…

AIM To investigate the relationships between the shape of an object and the time taken for a substance to diffuse into its center and to investigate the correlation between surface area and volume in regards to cellular transport. BACKGROUND THEORY / INTRODUCTION Cells are the basic unit of life of which all living organisms are built upon, they are the smallest living organizational unit and they all come from pre-existing cells which has been supported by several scientists in the formation of…

determine the correlation between a solution’s salt concentration and its density. Also, it was to determine what equipment would be best to use to measure volume precisely and accurately. Densities of a series of known salt solutions were trialed three times and then averaged. By following the procedures, the unknown salt solution was determined and graphed to calculate the percent salt to the sample. Introduction In chemistry there are often times an unknown solution’s density must be determined…

Latzer (2013). In relation to mass communication, media convergence incorporates insights and methods to describe, characterises and understanding of digital media (Latzer, 2013). Convergence adequately describes the relationship between mass media and digital media. Mass media refers to ability to communicate openly and internationally to many receivers within a limited amount of time. The latest digital forms have expanded speed, capacity, and transmission efficiently of mass media platforms (Mcquail…

GS104 Lab Report Experiment # 1 Measurement, Length, Mass, Volume, Density & Time David Case: January 17, 2015 Experiment #1 Measurement, Length, Mass, Volume, Density, & Time Objectives: To make basic distance, mass, density, and time measurements.

Purpose The purpose of performing part I of this lab was to study the relationship between surface area/volume with regard to rate of diffusion. We used treated agar blocks to model artificial cells because their surface area and volume could be easily measured, and they visually show the amount of diffusion. By using blocks of different sizes (and with different SA: V ratios, we can compare the rate that diffusion occurred for each block. Background Information All molecules are constantly in motion…
