TOPIC:- imperfection in solid’s NAME:-MILAN RAJAWAT Regd. No.:-11004886 Section:-M2R16 Roll No.:-B16 Subjet:-MEC208 INTRODUCTION For a crystalline solid we have tacitly assumed that perfect order exists throughout the material on an atomic scale. However‚ such an idealized solid does not exist; all contain large numbers of various defects or imperfections. As a matter of fact‚ many of the properties of materials are profoundly sensitive to deviations from crystalline

DRY ICE Introduction The topic I have chosen to write this report on is dry ice (also known as liquid nitrogen). This topic has quite an interest to me in a sense that I am curious about the dry ice as a whole. I have seen it being used but always thought about the manufacturing behind it. I am hopeful in finding out information such as what exactly dry ice is‚ how the dry ice is made/formed‚ what it has use for‚ and who was behind the making or discovery of dry ice. Some questions that I

Anyone on a clear liquid diet is doing that due to medical procedures such as surgery‚ having the flu‚ or sometimes other stomach disorders until they can go on solids again. The clear liquid diet is only that: foods that will go down easily and don’t require a lot of digesting. The clear liquid diet helps the person on it to stay hydrated enough for the body to function‚ and also provides you with electrolytes that are needed as well. This type of a diet is usually for the shorter term until whatever

Liquid Nitrogen Randi Pinter Community College of Aurora Rebecca Hoenigman Chem 101-360 Sitting in a classroom with a guest speaker‚ wondering what was in the tank and why there were carnations nearby. As a young student‚ guest speaker days were an exciting thing to be a part of. The full history of the lesson may have been lost in time; but when the speaker dipped a carnation in a tub of liquid that was pouring smoke onto the classroom floor‚ the results of his actions had the power to make a

Angela Pierre Chem 112 Lab Due: 03/05/2015 Lab Report 14 Questions 1. Part A.3. Some of the cyclohexane solvent vaporized during the temperature versus time measurement. Will this loss of cyclohexane result in its freezing point being recorded as too high‚ too low‚ or unaffected? Explain. -The freezing point will be higher because the loss of solvent means that the molarity of solute is too high. The melting point will be lower than expected. 5. Part B.2. The solute dissociates slightly in the

ORGANIC CHEMISTRY LAB 2: Separation of Organic Liquid Mixtures Introduction: In this experiment‚ a mixture of two compounds‚ cyclohexane and toluene‚ was separated into fractions by the techniques of simple and fractional distillation. The individual fractions that were gathered from the distillation were analyzed using gas chromatography (GC) and used to compare the efficiencies of the two different distillation techniques. The ultimate goal of this experiment was to determine whether simple

A solid argument consists of a claim‚ reasons/evidence and conclusion. “Reasons are beliefs‚ evidence‚ metaphors‚ analogies‚ and other statements offered to support or justify conclusions. When a writer has a conclusion she wants you to accept‚ she must present reasons to persuade you that she is right and show you why. You cannot determine the worth of a conclusion until you identify the reasons” (Browne & Keeley‚ 2012‚ p.28). Absent reasons or conclusion the argument is weak‚ unclear‚ pointless

THE PURITY AND PURIFICATION OF SOLIDS MELTING POINTS ABSTRACT Melting points of different mixtures of naphthalene and biphenyl were examined in this lab. Samples of these various mixtures were collected and tested by different individuals in the lab in order to find the eutectic point of biphenyl. Unknown substances were then tested using the mixture melting point method in order to determine their identities. INTRODUCTION The melting point of a solid is the temperature where the substance
