volume, moles, pressure. * R is the universal gas constant that relate the four properties of gases in one relationship. Write down the formula equal to R. PV = R nT * What is the unit that you used for R? Atm.L\k.mol * Hydrogen gas has properties very nearly like an ideal gas. Write down the equation for the production of H2 gas Mg(s) + 2HCl(aq) MgCl2(aq) + H2(g) * In our experiment, the total pressure of the gas was

saturated liquid refrigerant-134a. The piston is free to move, and its mass is such that it maintains a pressure of 900 kPa on the refrigerant. The refrigerant is now heated until its temperature rises to 70oC. Calculate the work done during this process. The freely-moving piston can be interpreted as giving a constant pressure process such that P1 = P2 = P = 900 kPa. For a constant pressure process, the concept that the work is the area under the path is particularly simple. That area is a rectangle

subjected to internal pressure. This experiment aids the understanding of how a cylinder withstands internal pressures and how the behaviour of stresses varies at different points along the cylinder radius. Theory Using Lame's equations for a thick cylinder subjected to an internal pressure, the following equations, based on pressure and geometry, may be obtained to calculate hoop and radial stresses: σθ= PK2-1(1+ R22r2) σr= PK2-1(1- R22r2) Where: P = Internal pressure R1 = Internal radius

CHM 1101 Introductory Chemistry Dawn Fox Medeba Uzzi August, 2007 Compiled and edited by Medeba Uzzi Authors’ Note This document is an initiative by the authors in an attempt to deal with what they think may be one of the reasons contributing to the relatively high failure rate in the introductory Chemistry course (CHM 1101) at the University of Guyana. It was brought to our attention that many first year students taking CHM 1101 are unable to efficiently cope with the frenetic pace

investigate the distribution of radial and hoop stresses and strains throughout the walls of a thick- walled cylinder under internal pressure and to compare experimental results with the theoretical Lamé predictions. The experiment aims to teach students about: Stress and Strain distributions in the walls of a thick cylinder under internal pressure. How to predict the stress and strain in thick cylinder. The use of strain gauges in mechanical design. Shear stress in thick cylinders

since the acquisition in late June or significantly accelerated. You can see the reservoir of acquisition efforts abroad began to increase, this is actually a good time to return the funds. If you always store food to be up, its loan pressure, as well as some storage pressure force majeure will allow food store's profits, so when the State Reserve force recently acquired wheat actively send food storage is the best choice. From nearly two years of milling enterprises' survival environment, this year's

Early on Friday morning, the students of Mr. Jackson’s grade 12 chemistry class in room 269 were getting ready to complete an lab experiment. The experiment required the usage of the bunsen burners. The students were put into groups and promptly followed the procedure on what they had to do. One group of students had left their station in order to speak with the teacher. However, within seconds, the bunsen burner that they had left unattended proceeded to tip over sparking a fire. The fire quickly
