Uma uhlala esihlalweni sokhuni, ubuso besihlalo sokhuni buyafudumala. Ngokuphambene nalokho, uma uhlala esihlalweni esenziwe ngepulasitiki noma ngensimbi, ubuso besihlalo sensimbi noma sepulasitiki abuzizwa bufudumele ngemva kokuhlala kuso. Kungani ubuso besihlalo sokhuni bufudumala, kanti ubuso besihlalo sensimbi abufudumali? Kungani ukulala phansi okubandayo ngaphandle komatrasi kungabanga ubuhlungu? Wake wagqoka ijakethi ebandayo? Kungani amajakethi amaningi abandayo enziwe ngoboya? Kusenezinto eziningi okufanele uzicabange futhi uzibuze ngazo ezihlobene nesihloko sokudluliselwa kokushisa ngokuqhutshwa komoya.
Lungisa ikhandlela kanye nocezu lwentambo encane. Bamba uhlangothi olulodwa lwentambo bese uthinta olunye uhlangothi lwentambo elangeni lekhandlela. Linda imizuzwana embalwa kuze kube yilapho isandla sakho sizwa sishisa. Kungani isandla sakho sizwa sishisa? Lapho olunye uhlangothi lwentambo luthinta ilangabi lekhandlela, ukushisa kuhamba kusuka elangeni lekhandlela (izinga lokushisa eliphezulu) kuye komunye umkhawulo wentambo (izinga lokushisa eliphansi). Lokhu kudluliselwa kokushisa kubangela ukuthi izinga lokushisa lokuphela kwentambo ethinta ilangabi likhuphuke. Umehluko wokushisa phakathi kokuphela kwentambo ethinta ilangabi lekhandlela kanye nolunye umkhawulo wentambo kubangela ukuthi ukushisa kusuke ekugcineni kwentambo ethinta ilangabi kuye ekugcineni kwentambo ethintwe yisandla sakho. Ukuba khona ukudluliselwa kokushisa Lokhu kubangela ukuthi izinga lokushisa lohlangothi oluthintwe lwentambo likhuphuke. Ukushisa kuya esandleni sakho esipholile, okwenza isandla sakho sizizwe sishisa.
Uma ingxenye eyodwa yento ine shu ukuthintana nento ephansi lokushisa, ukushisa ukusuka entweni enokushisa okuphezulu kuya entweni enokushisa okuphansi. Amandla engeziwe abangela ukuthi ama-athomu nama-molecule akha into ahambe ngokushesha. Uma ehamba, ama-molecule anamandla e-kinetic (EK = ½ mv)2). Ama-molecule ahamba ngokushesha (anamandla amakhulu e-kinetic) ahlangana nama-molecule aseduze kwawo. Lawa ma-molecule abe esehlangana namanye ama-molecule aseduze kwawo. Njalo njalo. Ngakho ama-molecule ahlangana, edlulisela amandla. Ukudluliselwa kokushisa okwenzeka ngokushayisana phakathi kwama-molecule akha into kubizwa ngokuthi ukudluliselwa kokushisa ngokuqhutshwa komoya.
Ifomula yokudlulisa ukushisa ngokuqhutshwa komoya
Into engakwesobunxele inokushisa okuphezulu (T)1) kuyilapho into engakwesokudla inokushisa okuphansi (T2Ngenxa yomehluko ekushiseni (T)1 - T2), ukushisa kuhamba kusuka entweni enokushisa okuphezulu kuya entweni enokushisa okuphansi (isiqondiso sokugeleza kokushisa singakwesokudla). Into lapho ukushisa kudlula khona inendawo enqamulayo (A) kanye nobude (l).
Ngokusekelwe emiphumeleni yokuhlolwa, ukushisa okudluliselwe ngesikhathi esithile (Q/t) kuhambelana ngqo nomehluko wokushisa (T).1 - T2), indawo enqamula isigaba (A), izakhiwo zento (k = ukuhanjiswa kokushisa) futhi ilingana ngokuphambene nobude bento. Ifomula yesilinganiso sokudluliselwa kokushisa ngokuqhutshwa:
Incazelo: Q/t = izinga lokudlulisa ukushisa, k = ukuqhuba ukushisa, A = indawo enqamula isigaba, T1 = izinga lokushisa eliphezulu, T2 = izinga lokushisa eliphansi, l = ubude bento.
Ukusetshenziswa kokudluliselwa kokushisa ngokuqhutshwa komoya
Kungani amathayili ezwakala epholile kunekhaphethi? Amathayili anomoya wokushisa omkhulu kunamakhaphethi. Ngakho-ke, amathayili ayizikhombisi ezinhle zokushisa, kanti amakhaphethi ayizikhombisi ezimbi zokushisa. Uma sinyathela ikhaphethi, ukushisa kugeleza kusuka ezinyaweni zethu kuya kukhaphethi. Lokhu kwenzeka ngoba izinga lokushisa lomzimba wethu liphakeme kunezinga lokushisa lekhaphethi. Amakhaphethi ayizikhombisi ezimbi zokushisa, ngakho-ke ukushisa okugeleza kusuka ezinyaweni zethu kuqongelela ebusweni bekhaphethi, okwenza ikhaphethi ifudumale. Uma sinyathela amathayili noma izinto zobumba, ukushisa kugeleza kusuka ezinyaweni zethu kuya kumathayili noma izinto zobumba. Ngenxa yokuthi amathayili ayizikhombisi ezinhle zokushisa, ukushisa akugcini ebusweni bamathayili. Ukushisa kugeleza kahle, okwenza izinyawo zethu zizwe zibanda. Uma indlu yakho isendaweni ebandayo, kufanele umboze phansi kwekamelo lakho lokulala ngekhaphethi ukuze umzimba wakho ungalahlekelwa ukushisa. Ngokuphambene nalokho, uma indlu yakho isendaweni eshisayo, akufanele umboze phansi kwekamelo lakho lokulala ngekhaphethi ngoba ngeke uzizwe upholile kodwa ushisa 😉
Ukulala phansi ngaphandle komatrasi kungabangela ukugula. Kungani? Lokhu kungenxa yokuthi ukushisa okukhulu kudluliselwa kusuka emzimbeni wakho kuya phansi. Ukushisa kungamandla asebenzayo. Uma umzimba wakho ulahlekelwa ukushisa okuningi, amazinga awo amandla ayancipha. Uma untula amandla, ungagula!
Uyini umsebenzi wamafasitela neminyango? Kungani iminyango namafasitela kufanele kwenziwe ngokhuni? Ebusuku, izinga lokushisa lomoya ngaphandle kwendlu liphansi kunezinga lokushisa lomoya ngaphakathi kwendlu. Lo mehluko ekushiseni komoya ubangela ukushisa ukuthi kusuke ngaphakathi endlini kuye ngaphandle. Ngakho-ke, ebusuku sivame ukuvala iminyango noma amafasitela. Ngaphandle kokuhlose ukuvimbela izigebengu, omunye wemisebenzi yamafasitela noma iminyango ukuvimbela ukushisa ukuthi kuphume endlini. Ngokuvamile iminyango noma amafasitela enziwe ngokhuni. Ukushisa kokhuni kuphansi ngokwanele ukuthi kungasebenza njengesivikelo sokushisa. Omunye umsebenzi wamafasitela noma iminyango ukubamba umoya. Umoya ovaleleke ngaphakathi kwefasitela noma umnyango usebenza njengesivikelo esihle (ukuvimba ukushisa ukuthi kuphume). Ukushisa komoya kuphansi kakhulu. Uma ukushisa kwento kuphansi, kuba nzima kakhulu ukuthi ukushisa kudluliswe ngokushayela ngaleyo nto.
Ngaphandle kokugcina isimo sethu njengabantu abaphucukile nabavamile 🙂, izingubo ziphinde zisebenzele ukugcina izinga lokushisa lomzimba lizinzile. Izingubo esizigqokayo zivame ukulungiswa ukuze zivumelane nezinga lokushisa lomoya. Uma izinga lokushisa lomoya liphansi impela, izingubo esizigqokayo zijiyile. Amablankethi noma izingubo ezijiyile (amajakethi, njll.) avimbela umoya ukuthi ungahambi kahle. Umoya uvaleleke phakathi kwesikhumba nejakethi noma ingubo. Ngenxa yokuthi kunomehluko wokushisa phakathi komzimba wethu nomoya ovalelekile, ukushisa kuhamba kusuka emzimbeni kuye emoyeni. Ukushisa okwengeziwe okuvela emzimbeni kubangela ukuthi izinga lokushisa lomoya ovalelekile likhuphuke (umoya uba shushu). Bheka ithebula lokuqhuba ukushisa elingenhla. Inani lokuqhuba ukushisa lomoya lincane kakhulu. Ngakho-ke, ukushisa akukwazi ukuphuma emzimbeni. Izinga lokushisa lomzimba wethu lihlala lizinzile. Uma singagqoki ijakethi lapho umoya ubanda kakhulu, ukushisa kuyaphuma emzimbeni wethu. Lapho ukushisa okuningi kuphuma emzimbeni, kulapho umzimba ulahlekelwa khona amandla amaningi.
