Ashley Robins 9/13/11 Honors Chemistry Period 4 Density Lab Purpose: 1. To determine the density of a solid using different laboratory techniques for measuring volume. 2. To use the intensive property of density to identify an unknown substance. Procedure: 1. Obtain a bag marked with a number containing a cube and a cylinder from the teacher. Record the number on the bag in the data table. Density of a cube: Using a balance‚ record the mass of the cube to the nearest tenth of a gram

Williams Ozuma Environmental Impacts of Offshore Drilling Offshore drilling Energy bonanza or Environmental disaster? if any choice is going to be made‚ one fact that makes the environment much germane than the offshore energy bonanza is that unlike energy‚ the environmental does not have a substitute and if it is destroyed we would have no where to live. Industrial extraction of hydrocarbons did not move offshore until the early 1950s. The first offshore platform was built off the

Experiment 1: Density | Purpose: To determine the density of the following liquids and solids. Data/Observation: Part A Sample | Distilled Water (g) | Methanol (g) | Glycerol (g) | Mass of empty cylinder | 41.1 g | 40.4 g | 41.1 g | Mass of cylinder + liquid | 51.2 g | 48.2 g | 53.8 g | Mass of liquid | 10.1 g | 7.8 g | 12.7 g | Calculations: Density of liquid = Mass/Volume = g/mL Distilled Water = 10.1g/10mL = 1.01 g/mL Methanol = 7.8g/10mL = 0.793 g/mL Glycerol = 12.7g/10mL

Density: Using Experimental Techniques to Solve an Inquiry based problem 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

Determination is a positive emotion that involves persevering towards a difficult goal in spite of obstacles.[1][2] Determination occurs prior to goal attainment and serves to motivate behavior that will help achieve one’s goal. Empirical research suggests that people consider determination to be an emotion; in other words‚ determination is not just a cognitive state‚ but rather an affective state.[3] In the psychology literature‚ researchers have studied determination under other terms‚ including

Effects of offshore drilling Offshore drilling also known as Seaward boring is a topic that has brought controversy for a few decades‚ the drilling in United States coast has been detrimental in helping the economy and political stand in the country; however this process is extremely dangerous to the environment‚ individuals and animals‚ Case in point‚ the oil slick in the Gulf a couple of years prior significantly harmed nature and marine life Boring ashore is an immense extend in itself in addition

Pande Putu Adysti Kardi Compare & Contrast 5/4/2014 Should the Government Expand Off Shore Drilling in the U.S.? The crude oil industry has become prominent since mid 19th century. Ever since the Industrial Revolution‚ the development of drilling methods has brought oil into a drastically larger extent of mass production. Petroleum is one of the important extracted compositions of crude oil in the U.S. Until today‚ it is globally used mainly as fuels in transportation. Other uses include heating

Period 7 9/17/13 The Density of Metals Lab BACKROUND: Density is a constant relationship between the mass and volume of a specific type of matter. Measurements of both mass and volume can be obtained for a metal sample. The relationship can be shown graphically by plotting the volume of a sample on the horizontal x-axis and the mass of the sample along the vertical y-axis. Plotting the values for several samples‚ a linear relationship can be seen for a density (slope=density). PURPOSE: During this

The ratio of the mass per unit volume is density‚ d and is written as (D = m/v). Using the metric system‚ the ratio for solids and liquids is expressed in g/mL or g/cm. Matter expands and contracts according

Nutrition Density Essay After having calculated the nutrient density of seven food groups in a spreadsheet‚ the food group that came to have the highest Nutrient Density was the vegetable group obtaining an average of 7.76712 Nutrient Density. The food group that came to have the lowest Nutrient Density was the “junk food” group‚ having an average of 0.24845 Nutrient Density. One of the factors that contribute to foods having a high or low Nutrient Density is the amount of calories. I noticed that
