Lefatšeng leo ho lona boiketlo le katleho e leng tsa bohlokoa, libotlolo tsa thermos li fetohile ntho e hlokahalang letsatsi le letsatsi ho ba bangata.Lijana tsena tse ncha, tse tsejoang hape e le thermoses kapa li-mugs tsa maeto, li na le bokhoni bo makatsang ba ho boloka lino tseo re li ratang li chesa kapa li bata nako e telele.Empa thermos e sebetsa joang ka boselamose ba eona?A re ke re ikakhele ka setotsoana ka har'a mahlale a makatsang ao metsoalle ena ea bohlokoa e nang le bokhoni ba ho itšireletsa.
Tlhaloso ea molao-motheo
Ho utloisisa hantle tšebetso ea ka hare ea thermos, re tlameha ho utloisisa metheo ea ho fetisa mocheso.Ho fetisa mocheso ho etsahala ka litsela tse tharo: conduction, convection le radiation.Thermos e sebelisa mekhoa ena kaofela ho etsa bonnete ba ho kenya letsoho.
Ntlha ea pele, kamore e ka hare ea botlolo hangata e entsoe ka likhalase tse peli kapa tšepe e sa hloekang.Moqapi ona o fokotsa ho khanna, ho thibela mocheso ho tloha pakeng tsa mokelikeli le tikoloho ea ka ntle.Sebaka se pakeng tsa marako a mabeli sea ntšoa, 'me se etsa sekheo.Vacuum ena ke insulator ea bohlokoa khahlano le conduction le phetiso ea mocheso oa convection.
Ho phaella moo, bokaholimo ba setshelo bo koahetsoe ka lesela le tšesaane la lintho tse bonahalang, tse kang silevera kapa aluminium.Mocheso ona o benyang o fokotsa mocheso oa mahlaseli hobane o bonahatsa matla a mocheso a lekang ho tsoa.
