Yiziphi izinhlobo ezahlukene zokudlulisa ukushisa?

ukudluliselwa Heat ngokwemvelo evumela ukuba khona yonke ngesimo lapho thina sonke ejwayele. Kunzima ukusho ukuthi izwe ngabe unjani, zinyamalale Inqubo yokudlulisa ukushisa okwesikhashana. Ake sihlolisise lokho kukhona izinhlobo ezahlukene zokudlulisa ukushisa, futhi ukuthi kushiwoni kwethemu.

Ngokusho incazelo olwamukelwa, ukudluliswa ukushisa kuyinqubo ngokomzimba lapho energy ezishisayo, noma ngenye indlela lisabalaliswe emizimbeni eziningana nge ngamazinga ahlukene bafudumale. Inqubo uyama uma zokulinganiswa lokushisa, noma ngamanye amazwi, lapho efika yakhoibrium thermodynamic.

Sibala iziphi izinhlobo eziyisisekelo ukudluliswa ukushisa: Ukubika Inkinga YeWindows, ukushisa conduction ngemisebe. Zonke ezinye ukuhluka okungenzeka inhlanganisela ngezindlela ezimbili noma eziningana eziyisisekelo. Leli phuzu kumelwe ngaso sonke isikhathi ukuba kubhekelwe.

Ukubika Inkinga YeWindows ejwayelene kuwo wonke umuntu kusukela ebuntwaneni. Ngokusobala lesiLatin elithi «convectio» kusho yokudlulisa. Ngakho-ke, uma kukhona ukudluliswa Ukubika Inkinga YeWindows ukushisa ageleza efana uqobo. Kuyinto ejwayelekile amagesi futhi uketshezi, kodwa ngezinye izikhathi kwenzeka kwezinye izinto ngobuningi. Mela usuku ehlobo kushisa: phezu komhlabathi evuthayo ufasimbe lula kubonakale - lokhu ukuhlanekezela kungenxa yokwenyuka umoya. Lapho kuqala ebusuku lapho Ukushisa umphumela yelanga iyeke lokushisa zokulinganiswa nqubo iqale phansi futhi emoyeni: inhlabathi yazisa shisisa aphansi zamatshe emkhathini (kuba okuxubile ukudluliswa ukushisa indlela) abavuka phezulu, esikhundleni wuhlelo cooler air uquqaba. Nakhu esinye isibonelo: ubeke heater esitsheni ngamanzi luwuphendule inetha. A ngokuqaphelisisa of ebonakalayo ezihambayo yamanzi. mass Zezıhlabane dengwane umthombo ukushisa, futhi esikhundleni sabo kuza ngaphansi kwezingaqhwa.

Yini enye engcono kunalokhu engxoxweni emnandi phezu inkomishi yetiye ezishisayo ku umkhuhlane ebusuku ebusika? Kwanele okwesikhashana ukusiphazamisa futhi kuthathe livela spoon onqenqemeni metal ngokushesha ebesibuyisela emuva isandla sakhe, ukugwema ukushiswa. Isizathu sisobala - ezinye izinhlobo ukushisa ngokushesha kakhulu ukufuthelana spoon metal kuze lokushisa lamanzi endebeni. Sikhuluma ukushisa conduction. Izimo lapho omunye ungahlangana nge uhlobo enjalo ukushisa ukudluliswa, inani elikhulu. Ake uchaze ukuthi: conductivity ezishisayo - ukudluliswa ukushisa umzimba ingxenye eliwu umzimba ukubanda esebenzisa izinhlayiya abamelwe (ama-electron, ama-athomu, amangqamuzana omoya). Ikesi ekhethekile - ukudluliswa ukushisa phakathi tintfo letehlukene contact. izinto ezehlukene zinezidingo conductivities ezahlukene ezishisayo. Ngakho, uma umuntu ekupheleni ukushisa inyanda yezinkuni, bese yesibili kuyoba abandayo. Kodwa uma wenza lesi silingo ngogodo metal, umphumela kuphambene. Lo mehluko wenza kungenxa umehluko Sakhiwo sangekhatsi izinto.

Uma ucabangela izinhlobo ukudluliswa ukushisa, ingasaphathwa ukudluliselwa ukushisa bemisebe. Umthombo ukushisa edonsa oscillations kagesi nge nombono ka-1000 microns (spectrum infrared). Amandla yokucucuza ukukhanya kanye lokushisa komzimba evuthayo kukhona ngokulingana oqondile. Ukuze uqonde ukuthi emisebeni ithwala ukushisa, zikwazi ukwenza ukuhlola okuncane - ukwenza womlilo ufake kuwo phakathi kwakhe nabantwana umlilo ekhanyayo. Naphezu ukuthi siyini isithiyo, ukushisa kuauka. Noma ukubheka ikati elisemandleni ubusika phezu efasiteleni elangeni, efuna. Kulula - kulezi zibonelo, amandla ezishisayo idluliswe bemisebe. Omunye isici okufana Inqubo yokudlulisa ukushisa - ekubusweni abezindaba Lesisemkhatsini. Uma ukudluliswa kwenzeka Ukubika Inkinga YeWindows we ketshezi (igesi), kuyilapho ezishisayo conductivity - izinhlayiya, emisebeni ayidingi "umlamuleli". Ngakho, ilanga sihamba ekushiseni kwalo ngokusebenzisa cleaner iwukusebenzisa ngemisebe.
