Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

Density is how compact particles are inside an object. Objects can be different sizes but have the same density because the density depends on how close particles are together‚ not the size of an object. The density of water is 1 g/㎤. Any object with a density less than that will float. Any object with density more than that will sink. Carbon dioxide‚ or CO2‚ also played a big role in this experiment. Many soft drinks contain CO2. Studies show that Sierra Mist had the most carbonation out of

Population Density Population density is defined by the number of people and the area size in which they reside. The effects of urbanization on the human race vary between cultures. However‚ there is clearly a relationship between population density and human behavior (Rosenbnerg‚ 2011‚ para. 1). Whether the answer is moving to a less dense area‚ or adapting to an urban area depends on individual personality and preference. For centuries‚ Americans have dealt with overcrowded cities in order
