Koyi game da canja wurin zafi:
Don fahimtar yadda ƙwanƙolin ƙura ke watsar da zafi, yana da mahimmanci a fahimci manufar canja wurin zafi.Ana ci gaba da canja wurin zafi daga wuraren da ke da zafi zuwa wuraren da ke da ƙananan zafin jiki don cimma daidaiton zafi.Akwai hanyoyi guda uku na canja wurin zafi: gudanarwa, convection da radiation.
Gudanarwa da haɓakawa a cikin thermos:
Thermoses sun dogara da farko akan hanyoyi guda biyu na canja wurin zafi: gudanarwa da convection.Wadannan hanyoyin suna faruwa ne tsakanin abubuwan da ke cikin flask din da bangon ciki da na waje na flask.

Gudanarwa yana nufin canja wurin zafi ta hanyar hulɗa kai tsaye tsakanin abubuwa biyu.A cikin thermos, Layer na ciki wanda ke riƙe da ruwa yawanci ana yin shi da gilashi ko bakin karfe.Duk waɗannan abubuwa biyu marasa ƙarfi ne masu sarrafa zafi, wanda ke nufin ba sa barin zafi ya gudana ta cikin su cikin sauƙi.Wannan yana iyakance canja wurin zafi daga abubuwan da ke cikin flask zuwa yanayin waje.
convection:
Convection ya ƙunshi canja wurin zafi ta hanyar motsi na ruwa ko gas.A cikin thermos, wannan yana faruwa tsakanin ruwa da bangon ciki na flask.Ciki na flask yawanci yana ƙunshe da bangon gilashi biyu, sarari tsakanin bangon gilashin ana fitar da wani yanki ko gaba ɗaya.Wannan yanki yana aiki azaman insulator, yana hana motsin ƙwayoyin iska da rage tsarin haɓakawa.Wannan yana rage asarar zafi sosai daga ruwa zuwa iskar da ke kewaye.
Radiation da insulating caps:
Ko da yake gudanarwa da convection sune farkon hanyoyin hasarar zafi a cikin thermos, radiation kuma yana taka ƙaramin rawa.Radiation yana nufin canja wurin zafi ta igiyoyin lantarki.Koyaya, kwalabe na thermos suna rage hasara mai hasara ta hanyar amfani da abin rufe fuska.Waɗannan suturar suna nuna zafi mai walƙiya a baya a cikin flask, suna hana shi tserewa.
