Background The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. A mixture melting point is useful in confirming and used to indentify an unknown compound‚ which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition

temperature difference‚ while no heat will be exchanged between bodies of the same temperature‚ which are then said to be in "thermal equilibrium". Apparatus -1 glass thermometer * calorimeter * stop watch * and hot water Procedure- 1) we took hot water from the lab We put it into a calorimeter and put a glass thermometer into it. 2) We measured the intial temperature to be 81 degree celcius.

Equilibrium Kurt Wimmer’s film Equilibrium (2002) is set in color. It tells a story about how suppressing emotions eliminates war‚ and any books‚ art‚ or music is forbidden. Those who are caught being a sense offender has committed a crime punishable by death. The film demonstrates the true source of man’s inhumanity to man. The internal struggle within the characters throughout the film such as with the main character Cleric John Preston (Christian Bale)‚ contributes to the theme of the Truth of

Physics Lab Report Format General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a “one size fits all”‚ therefore this sample lab report should only be used as an example. Any lab report should have the following features:

Engineering Laboratory (Lab) Report Department of Engineering Faculty of Engineering and Science‚ University Tunku Abdul Rahman (UTAR) 1. Introduction Laboratory (Lab) reports are the most frequent document written by engineering student. These reports can contribute a significant amount of marks and yet little time or attention is devoted in understanding on how to write them well. The aim of this document is to provide a general guideline on writing a lab report. A lab report should not be

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

CHEMISTRY LAB REPORTS How to Write a Lab Report Lab Reports gives the explanation of the experiment done Lab reports are an essential part of all laboratory courses and usually a significant part of your grade. If your instructor gives you an outline for how to write a lab report‚ use that. Here ’s a format for a lab report you can use if you aren ’t sure what to write or need an explanation of what to include in the different parts of the report. A lab report is how you explain what you did

Yeast Lab Report Guidelines 1. Lab reports are to be computer-generated and double-spaced. All sections of the report must be written in paragraph form. 2. Do not use encyclopedias (Internet or otherwise)‚ dictionaries ((Internet or otherwise)‚ or personal web pages as sources for the report‚ this includes Wikipedia. You may use a textbook‚ lab manual‚ and/or article(s) in a published journal. You can find journal articles by going to the library website: http://www.lib.clemson.edu/ and selecting
