Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Liquid Nitrogen Liquid nitrogen is nitrogen in a liquid state at a very low temperature. Its chemical formula is N2. Manufacturing of Liquid Nitrogen Liquid nitrogen is made by cooling and compressing air straight from the atmosphere. The type used to produce large amounts of liquid nitrogen looks vastly different but really happens is that air squashed and cooled . When you squash it‚ air molecules are forced closer together. If you also cool it down the molecules can slow down enough to

Lab 3 Viscosity Measurement Arbnor Emini B1‚ acjz758@city.ac.uk Abstract The flow rates of a series of dilutions of glycerol solutions (100% glycerol and 98% glycerol concentration) were measured using a viscometer. The intrinsic viscosity of the solution was found along with other quantities such as shear stress and shear rate for example. The objective of this laboratory experiment was to measure and determine the viscosities of glycerol/water solutions using a rotational viscometer. Introduction

Allison Oneal Chemistry I June 20‚ 2013 Dr. Michael May Properties of Gases I. Abstract The purpose of this experiment is to examine the properties of several gasses‚ which were the products of a reaction‚ and examine the way the gasses react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Experiment Before I began the experiment I gathered all my supplies from the given list in the lab manual.
