I Coefficient komugqa ukunwetshwa - kungenzeka ukubala zonke

Wonke umuntu umsindo ngokuqinisekile ajwayelekile amasondo ekalishi. Noma umsindo amasondo tram. Wonke umuntu uyazi ukuthi isizathu igebe at kwalapho phakathi komzila. Futhi lokho obhakwe? Impendulo ilula - isinxephezelo ukunwetshwa wesitimela lapho sishiswa ngakho. Lokhu kubuye Eqinisweni eyaziwa ukuthi ngesikhathi Ukushisa komzimba ukwandisa futhi zizincane kakhulu uma selehlile. Ngezinga elithile, la ukunwetshwa noma nokuncipha kuphindwe ukuvaleka kwegebe ukunwetshwa komugqa.

Theory yamangqamuzana ukunwetshwa umzimba lapho ukufuthelana ngenxa ukwanda ukuthi lingakanani ijubane lokuya zama-athomu nezinhlayiyana ezincane. Ngenxa yalokho, wathi eheleni vibration amplitude ama-athomu ukwanda, kanti ngenxa yalokho - ukwandisa izilinganiso komugqa emzimbeni. Futhi njengoba iyokwanda kungaba azimisele kusetshenziswa indlela, olusebenzisa Coefficient ukunwetshwa komugqa.

Manje sinesizathu ukuchaza ezingokomzimba Coefficient. Ubonisa indlela ukwandisa lapho ukufuthelana-1 ° C we obuphelele umzimba. Inani lale amancane ihlukile impahla ngayinye. Ngakho, komugqa ukunwetshwa Coefficient steel kuyinto 0.000011 ukuba 1 ° C. Yini ngempela value enjalo singakuqonda ngokubheka isibonelo esilula. Uma Umhlaba yenkabazwe ukugoqa yensimbi wire kabani Ubude 40-000, ukwanda lokushisa ngo-1 ° C kuzokhulisa ubude bentambo ku ayi-400.

I komugqa ukunwetshwa Coefficient kubaluleke kakhulu noma imuphi unjiniyela. It ikuvumela ukuba acabangele ushintsho ubukhulu iconsi nezinga lokushisa komzimba. Ngakho, uma kungakapheli nonyaka lokushisa emzini izoshintsha ukusuka plus amahlanu degrees Celsius ukuba degrees amahlanu Celsius, kuzobangela ukushintsha okuphawulekayo endleleni ubude komzila efanayo. Uma kunjalo okuqinile, umphumela uyoba ukugoba yabo. Lokho ukugwema into enjalo futhi wenze igebe phakathi komzila ngesikhathi kubekwa yabo.

Ukuze izinto ezahlukene kuzohluka ukubaluleka Coefficient. Ukuze steel ukubaluleka kakade ekhonjiwe, a komugqa ukunwetshwa Coefficient aluminium kuyoba 0.0000024 ukuba 1 ° C.

Nokho, ingxoxo ethulwa nezibonelo ahlupheke othile owodwa sidedness. Uma sikhuluma okwandisa ubukhulu umzimba lapho ukufuthelana, okwandisa hhayi kuphela ubude, kodwa futhi ezinye izinhlangothi - ukuphakama nobubanzi. Ukwanda usayizi kuzoholela uphakamise izwi, bese sikwazi ukukhuluma ukunwetshwa ivolumu zemizimba. Iqiniso liwukuthi umqondo kunalokho awusebenzi ukudla okuqinile futhi uketshezi.

A eksperimenti lelula ukuthi izoqinisekisa lokhu, wonke umuntu angakwazi ukwenza bebodwa. Beka iketela phezu komlilo, bagcwala amanzi kuze kube phezulu. Lapho amanzi lifudumeza up, iyokwanda ivolumu "abaleke" kusukela iketela. Kodwa kukhona ukusetshenziswa omuhle walokhu umphumela. Kuyaziwa thermometer uketshezi - ngalowo mgwaqo ukuthi wezokwelapha. Nabo futhi, zakhelwe umphumela nekwandzisa umtsamo lapho sishiswa ngakho.

ngezinye izikhathi Le nqubo bambalala onjalo ukwanda kuholela nemiphumela ebuhlungu. Ukuze bavale isikhala ukwanda kubalulekile ukusebenzisa amagadango akhethekileko. Abaningi babone uchungechunge olude amapayipi (umugqa) babeka phezu. Kungazelelwe aphume blue tube ukwakha amazombe omkhulu. Leli akulona amazombe elula, inani layo akuvunyelwe kuchazwa, ukubala kwaba isilinganiso esetshenziswa sokwanda komugqa. Kufana umugqa amazombe isinxephezelo ukwanda usayizi ipayipi.

Ungakwazi ukunikeza izibonelo eziningi ukusetshenziswa inqubo eqondile futhi volumetric ukunwetshwa, kodwa lezi zibonelo kwanele ukuba baqonde okushiwo lomkhuba. Yiqiniso, curious kakhulu ukuziphatha ezingasadingeki izinto ezithile, amanzi afanayo. Iqina lapho ivolumu akusho wehlise kodwa uyanda. Lena esinye isici esiqinisekisa izakhiwo esiyingqayizivele yamanzi.

Ngakho, kulesi sihloko ngesisekelo izibonelo elula ezichaza kabanzi ezithathwe ukuphila ngisho nomqondo onjalo njengoba kuchaziwe ukunwetshwa komugqa ukudla okuqinile kanye lwento ukunwetshwa Coefficient. Izibonelo ukusetshenziswa ukunwetshwa kwezobuchwepheshe kanye ekuphileni kwansuku zonke, unikezwa umbono oda ubukhulu Coefficient wathi.
