I. Objective The first objective of the measurement of thermal conductivity & one-dimensional heat conduction experiment was to identify three different metal specimens by comparing their experimentally determined thermal conductivities to known thermal conductivity values of existing metals. The second objective of the experiment was to establish a connection between the thermal conductivities & temperatures of the metal specimens. Thirdly‚ the contact resistance of the interfaces between

Evelyn Ramos CHEM LAB 201-003 Professor Ruddock Experiment #4 - Chemical Reactions Performed: 3/6/13 DUE: 3/13/13 Pre Lab Questions: 1. Before you can write a chemical equation‚ what must you know? You have to know what the products and reactants are. 2. What observations might you make that suggest that a chemical reaction has occurred? If a gas is produced or precipitates are formed that indicates chemical reaction. Also‚ if color changes occur or

products produced. The uncertainty of this this measurement is ± 1 product. In order for this experiment to be controlled‚ many variable were identified and held constant. If these variables were not to be held constant than the findings of this experiment would be meaningless because there would be no way of desiring if the independent variable was the cause of the changes which were recorded In this experiment‚

Experiment #4 (10/31/14) Lab Review Objective To introduce the basic molecules of life and to test for their presence in different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes

Edward Dickson CHE101 DS-01 Experiment Date 7/21/2013 Report Submitted 7/21/2013 Title: Experiment #8: Ionic Reactions Purpose: In this lab we will work with aqueous solutions of ionic substances and determine if they are soluble. If the solution appears milky than it is known as a precipitate reaction‚ meaning it is soluble‚ and that the ions separated and became surrounded by water. Precipitates in this experiment are electrically uncharged. To identify which compounds are

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used

Experiment 1 Laboratory Techniques and Measurements Purpose: To determine measurements of different items that vary from solids to liquids and be able convert those values to other SI units of measurement. Procedure: I used a variety of scientific tools such as; a ruler‚ beaker‚ graduated cylinder‚ volumetric flask‚ thermometer‚ burner‚ and digital scale to find unknown values of measurements for each of the indicated
