तापीय प्रसार

ताप के परिवर्तन के फलस्वरूप पदार्थों के लम्बाई, क्षेत्रफल एवं आयतन में होने वाले परिवर्तन को में होने वाले परिवर्तन को तापीय विस्तार (Thermal expansion) कहते हैं। प्रसार के समीकरण ठोसों का तापीय प्रसार thumb|रैखिक प्रसार लम्बाई क्षेत्रफल आयतन द्रवों का तापीय प्रसार गैसों का तापीय प्रसार शून्य डिग्री सेल्सियस के प्रारम्भिक तापमान पर आदर्श गैस के लिए, आयतनी ताप प्रसार गुणांक = 1/273,15 K−1 विभिन्न पदार्थों के ताप प्रसार गुणांक पदार्थ रैखिकगुणांक αat 20 °C(10−6 K−1)आयतनी गुणांक αVat 20 °C(10−6 K−1)टिप्पणीअलुमिनियम23.169अलुमिनियम नाइट्राइड4.2 a-axis, 5.3 c-axishttp://www.ioffe.ru/SVA/NSM/Semicond/AlN/thermal.html AlN thermal properties at Ioffe institute 25 नवंबर 2018 https://web.archive.org/web/20181117040716/http://www.ioffe.ru/SVA/NSM/Semicond/AlN/thermal.html 17 नवंबर 2018 dead13.7AlN is anisotropic Benzocyclobutene42126पीतल1957Carbon steel10.832.4CFRP– 0.8 Ashraf Ahmed Behrouz Tavakol Rony Das Ronald Joven Pooneh Roozbehjavan Bob Minaie Study of Thermal Expansion in Carbon Fiber Reinforced Polymer Composites Proceedings of SAMPE International Symposium Charleston, SC 2012AnisotropicFiber directionConcrete1236Copper1751Diamond13Ethanol250750Young and Geller College Physics 8th Young Geller 0-8053-9218-1Gallium(III) arsenide5.817.4Gasoline317950Glass8.525.5Glass, borosilicate3.3 http://www.schott.com/tubing/german/download/schott-brochure-technical-tubing-english.pdf Technical Glasses Data Sheet PDF schott.com 25 नवंबर 2018 https://web.archive.org/web/20151211123647/http://www.schott.com/tubing/german/download/schott-brochure-technical-tubing-english.pdf 11 दिसंबर 2015 live9.9matched sealing partner for tungsten, molybdenum and kovar.Glass (Pyrex)3.2Raymond Serway John Jewett Principles of Physics: A Calculus-Based Text https://books.google.com/books?id=VaroJ5BNuZAC 2005 Cengage Learning 0-534-49143-X 506 25 नवंबर 2018 https://web.archive.org/web/20170710212350/https://books.google.com/books?id=VaroJ5BNuZAC 10 जुलाई 2017 liveGlycerine485Gold1442Helium36.65Ice51Indium phosphide4.613.8Invar1.23.6Iron11.835.4Kapton20http://www.matweb.com/search/datasheettext.aspx?matguid=305905ff1ded40fdaa34a18d8727a4dc DuPont™ Kapton® 200EN Polyimide Film matweb.com 25 नवंबर 2018 https://web.archive.org/web/20181126005427/http://www.matweb.com/search/datasheettext.aspx?matguid=305905ff1ded40fdaa34a18d8727a4dc 26 नवंबर 2018 dead60DuPont Kapton 200ENLead2987Macor9.3http://www.corning.com/docs/specialtymaterials/pisheets/Macor.pdf Macor data sheet PDF corning.com 25 नवंबर 2018 https://web.archive.org/web/20110612081709/http://www.corning.com/docs/specialtymaterials/pisheets/Macor.pdf 12 जून 2011 liveMagnesium2678Mercury61182Molybdenum4.814.4Nickel1339Oak54http://www.forestry.caf.wvu.edu/programs/woodindustries/wdsc340_7.htm https://web.archive.org/web/20090330062350/http://www.forestry.caf.wvu.edu/programs/woodindustries/wdsc340_7.htm 2009-03-30 WDSC 340.
