Libotlolo tsa thermos, tse tsejoang haholo e le li-vacuum flask, li fetohile ntho eo batho ba bangata ba tlamehang ho ba le eona.Li re lumella ho boloka lino tsa rona tseo re li ratang li chesa kapa li bata ka nako e telele, li etsa hore e be tse loketseng maeto a malelele, maeto a ka ntle kapa feela ho thabela seno se chesang letsatsing le batang la mariha.Empa na u kile ua ipotsa hore na thermos e khona joang ho boloka likahare tsa eona li le mochesong o laolehileng ka nako e telele?Ka blog ena, re tla batlisisa ka mahlale a bakang tahlehelo ea mocheso ho tsoa ho thermoses le ho ithuta hore na ke hobane'ng ha li sebetsa hantle hakana ho insulating.
Ithute ka ho fetisa mocheso:
Ho utloisisa hore na botlolo ea vacuum e senya mocheso joang, ho bohlokoa ho utloisisa mohopolo oa ho fetisa mocheso.Mocheso o tsoela pele ho fetisoa ho tloha libakeng tsa mocheso o phahameng ho ea libakeng tsa mocheso o tlaase e le ho finyella tekano ea mocheso.Ho na le mekhoa e meraro ea ho fetisa mocheso: conduction, convection le radiation.
Ho tsamaisa le ho tsamaisa ka har'a thermos:
Thermoses e itšetlehile haholo ka mekhoa e 'meli ea ho fetisa mocheso: conduction le convection.Mekhoa ena e etsahala pakeng tsa likahare tsa botlolo le mabota a ka hare le a ka ntle a botlolo.
conduction:
Ho tsamaisa ho bolela ho fetisa mocheso ka ho kopana ka ho toba pakeng tsa lisebelisoa tse peli.Ka thermos, karolo e ka hare-hare e tšoereng mokelikeli hangata e entsoe ka khalase kapa tšepe e sa hloekang.Lisebelisoa tsena ka bobeli ke li-conductors tse fokolang tsa mocheso, ho bolelang hore ha li lumelle mocheso ho phalla habonolo ho tsona.Sena se fokotsa phetisetso ea mocheso ho tloha ka har'a botlolo ho ea tikolohong e kantle.
convection:
Convection e kenyelletsa ho fetisa mocheso ka motsamao oa mokelikeli kapa khase.Ka thermos, sena se etsahala pakeng tsa mokelikeli le lebota le ka hare la botlolo.Ka hare ho botlolo hangata ho na le marako a mabeli a khalase, sebaka se pakeng tsa marako a khalase se tlosoa ka mokhoa o itseng kapa ka ho feletseng.Sebaka sena se sebetsa joalo ka insulator, se thibela motsamao oa limolek'hule tsa moea le ho fokotsa ts'ebetso ea convective.Sena se fokotsa ka katleho tahlehelo ea mocheso ho tloha mokelikeli ho ea moeeng o potolohileng.
Likotlolo tsa mahlaseli le li-insulating:
Le hoja conduction le convection e le mekhoa ea mantlha ea ho lahleheloa ke mocheso ka har'a thermos, mahlaseli a boetse a phetha karolo e nyenyane.Mahlaseli a bolela ho fetisa mocheso ka maqhubu a motlakase.Leha ho le joalo, libotlolo tsa thermos li fokotsa tahlehelo ea mocheso ka ho sebelisa litlolo tse khanyang.Mekhabiso ena e bonahatsa mocheso o khanyang hape ka har'a botlolo, ho e thibela ho tsoa.
Ntle le sekoaelo sa vacuum, thermos e boetse e na le sekwahelo se sirelelitsoeng.Sekoahelo se boetse se fokotsa tahlehelo ea mocheso ka ho fokotsa phapanyetsano ea mocheso pakeng tsa mokelikeli le moea o ka ntle ka ntle ho botlolo.E etsa tšitiso e eketsehileng, ho netefatsa hore seno sa hau se lula mochesong o lakatsehang nako e telele.
Ho tseba kamoo thermos e tlosang mocheso kateng ho re thusa ho ananela saense le boenjiniere tse amehang ho theheng mokhoa o moholo hakana oa ho pata.Ka ho sebelisa motsoako oa conduction, convection, radiation le lids tse insulated, li-flask tsena li ntle haholo ho boloka mocheso oo seno se o hlokang, ebang se chesa kapa se bata.Kahoo nakong e tlang ha u noa kopi e chesang ea kofi kapa u natefeloa ke seno se batang ka lihora tse 'maloa ka mor'a ho tlatsa thermos ea hau, hopola mahlale a ho boloka mocheso o nepahetseng.
