Measurement of the Densities of Water and Alcohol Phuc Truong and Shane Steele Data Collected: September 8‚ 2014 2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass

The Density Challenge: A Complete Inquiry Activity Introduction Density has been an important part of science for a very long time. Density was discovered by Archimedes‚ a Greek mathematician‚ around 250 BC while determining whether a craftsman had replaced some of the gold in the King of Syracuse’s crown with silver. Density is the compactness of a substance. The new concept of density he discovered was used to expose the fraud. The purpose of this experiment is to make

Exploring Density Simulation Exploration: Login to the PHET Website. A basic property of any homogeneous substance is its density: the ratio of its mass to its volume. The density of a liquid or solid is an intensive property‚ which means that the density does not vary with the size of the sample but only depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another. The mathematical relationship is: Density= massvolume

The density of fractions 1‚ 2‚ and 3 are as follows: 1.49‚ 1.325‚ and 1.34 g/mL. These values areincorrect because the density should not have been over 1.0 g/mL. This is because the density of water is 1.0 g/mL‚ and the product should have had a mixture of ethanol and water‚ making the density lower. The measured weight of the vials and ethanol were incorrect due the scales.There are many factors that can cause a scale not to read the correct value. The first is the airflow underneath the weighing

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

The physical environment has determined to some extent‚ the distribution and density of Australia’s population. Discuss. People do not live evenly spread through the world. Australia is one of the counties that considered has a low population density. This is due to approximately 23 million population were distributed unevenly. Besides the physical environment‚ there are also a variety of other factors that have actually worked together to distribute in the Australia’s population that cannot be
