Webeler and published by . This book was released on 1971 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the product of viscosity and normal density have been made for pure He4 and for three He3-He4 mixtures (He3 mole fractions x3 of 0.005, 0.0475, and 0.1005) over temperature intervals which included their respective Lambda points. The measurements were made using a torsional crystal technique in which a piezoelectric, cylindrical quartz crystal was immersed in the sample fluid and driven at its resonant frequency in a fundamental torsional mode of vibration. The precision of the viscosity and normal density -against-T measurements for the mixture was greater than any previous measurements in the vicinity of experimental Lambda temperature. Doubly reduced plots of viscosity and normal density against T showed a slight but definite tendency for such curves to rotate clockwise about the (1,1) point with increasing x3 up to about 0.05. Values of viscosity were derived from the measurements by computing normal density as a function of reduced temperature. For each mixture, both viscosity and d viscosity/dT were continous across experimental Lambda temperature. No tendency was manifest for such curves to develop discontinuities as x3 decreased. It was, therefore, inferred that both viscosity and d viscosity/dT of pure He4 are continuous across experimental lambda temperature of pure He4. A further result obtained here is that up to mole fractions of 0. 1, the Lambda viscosity of the mixture viscosity (x3) bears a linear relation to the Lambda temperature (x3).--P. [i].

Available in PDF, EPUB and Kindle. Book excerpt: This work was begun quite some time ago at the University of Oxford during the tenure of an Overseas Scholarship of the Royal Commission for the Exhibition of 1851 and was completed at Banga lore when the author was being supported by a maintenance allowance from the CSIR Pool for unemployed scientists. It is hoped that significant developments taking place as late as the beginning of 1965 have been incorporated. The initial impetus and inspiration for the work came from Dr. K. Mendelssohn. To him and to Drs. R. W. Hill and N. E. Phillips, who went through the whole of the text, the author is obliged in more ways than one. For permission to use figures and other materials, grateful thanks are tendered to the concerned workers and institutions. The author is not so sanguine as to imagine that all technical and literary flaws have been weeded out. If others come across them, they may be charitably brought to the author's notice as proof that physics has become too vast to be comprehended by a single onlooker. E. S.

Pandorf and published by . This book was released on 1981 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a comprehensive analysis of three Experimental Series on the measurements of the effective viscosity of liquid He(4) with minute He(3) impurity taken with a Couette viscometer at temperatures between 0.05K and 2K, and at viscometer velocities which span the liquid helium critical velocities. A comprehensive theory of the velocity independent effective viscosity of liquid He(4) with minute He(3) impurity is developed for parallel plate geometry and is found to well represent the experimental measurements. The velocity independent viscosity measurements taken at temperatures above 0.8K were in agreement with the experimental measurements of the coefficient of viscosity made by Woods and Hollis Hallet. As the temperature T was lowered below 1.8K, the viscosity rose rapidly, approaching a T to the minus 9th power temperature dependence. Then below 0.8K the rapid rise quickly diminished. The diminution in the effective viscosity of liquid He4 of high purity is so rapid that it extrapolates to a nearby frictionless fluid at temperatures below 0.1K. This nearly frictionless property of liquid He4 should provide unprecedented opportunities for the development of inertial instruments of the highest precision.

Available in PDF, EPUB and Kindle. Book excerpt: Atkins' Physical Chemistry: Molecular Thermodynamics and Kinetics is designed for use on the second semester of a quantum-first physical chemistry course. Based on the hugely popular Atkins' Physical Chemistry, this volume approaches molecular thermodynamics with the assumption that students will have studied quantum mechanics in their first semester. The exceptional quality of previous editions has been built upon to make this new edition of Atkins' Physical Chemistry even more closely suited to the needs of both lecturers and students. Re-organised into discrete 'topics', the text is more flexible to teach from and more readable for students. Now in its eleventh edition, the text has been enhanced with additional learning features and maths support to demonstrate the absolute centrality of mathematics to physical chemistry. Increasing the digestibility of the text in this new approach, the reader is brought to a question, then the math is used to show how it can be answered and progress made. The expanded and redistributed maths support also includes new 'Chemist's toolkits' which provide students with succinct reminders of mathematical concepts and techniques right where they need them. Checklists of key concepts at the end of each topic add to the extensive learning support provided throughout the book, to reinforce the main take-home messages in each section. The coupling of the broad coverage of the subject with a structure and use of pedagogy that is even more innovative will ensure Atkins' Physical Chemistry remains the textbook of choice for studying physical chemistry.

This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The birth of this monograph is partly due to the persistent efforts of the General Editor, Dr. Klaus Timmerhaus, to persuade the authors that they encapsulate their forty or fifty years of struggle with the thermal properties of materials into a book before they either expired or became totally senile. We recognize his wisdom in wanting a monograph which includes the closely linked properties of heat capacity and thermal expansion, to which we have added a little 'cement' in the form of elastic moduli. There seems to be a dearth of practitioners in these areas, particularly among physics postgraduate students, sometimes temporarily alleviated when a new generation of exciting materials are found, be they heavy fermion compounds, high temperature superconductors, or fullerenes. And yet the needs of the space industry, telecommunications, energy conservation, astronomy, medical imaging, etc. , place demands for more data and understanding of these properties for all classes of materials - metals, polymers, glasses, ceramics, and mixtures thereof. There have been many useful books, including Specific Heats at Low Tempera tures by E. S. Raja Gopal (1966) in this Plenum Cryogenic Monograph Series, but few if any that covered these related topics in one book in a fashion designed to help the cryogenic engineer and cryophysicist. We hope that the introductory chapter will widen the horizons of many without a solid state background but with a general interest in physics and materials.
