Indaba yokubandakanyeka kweqhwa esakhiweni ngokujwayelekile naseduze kwezihlahla zezithelo ikakhulukazi kubangela impikiswano enkulu. Abanye bakholelwa ukuthi kuyadingeka ukunyathela iqhwa elizungeze izihlahla zezithelo, futhi kuthiwa kulusizo ngisho kubo; abanye bathi ukusebenza kweqhwa ezungeze izihlahla zezithelo kuzomane kubangele yonke inqwaba yezinkinga. Ngakho-ke sanquma ukubuza abalimi abanolwazi, sikhulume nabalimi abanezingadi zamahektha amaningana ukuze banikeze lonke ulwazi olutholile kuwe, bafundi bethu abathandekayo, futhi yilokhu okutholakale.

Kungani unyathela iqhwa elizungeze izihlahla?
Isizukulwane esidala, esedlule nanamuhla, sinyathela ungqimba lweqhwa elizungeze izihlahla zezithelo njalo ebusika. Leli siko lakhula emashumini amaningi eminyaka adlule, lapho abalimi beqala ukuhlanganyela hhayi engadini futhi bakhule ama-turnips, bese kuba namazambane, kodwa futhi baqala nokutshala izitshalo zezithelo ezahlukahlukene. Abalimi “baqala” izingane noma amanye amalungu omndeni bangene engadini noma baphume ngokwabo futhi bahambe bazungeze isihlahla ngasinye sezithelo, bechoboza iqhwa enhlabathini ngangokunokwenzeka.
Kunengqondo kulokhu - abalimi, futhi iningi labalimi banamuhla bayakholelwa ngenkani ukuthi iqhwa eliningi "libekwe", isistimu yezimpande ivikeleke kakhulu, ngaphezu kwalokho, iqhwa eliminyene alivumeli amagundane, ikakhulukazi amagundane, ukuthola amagxolo amnandi, ngoba ukuthi kufanele zivele endaweni evulekile, kepha bazokwemba amaqhwa eqhweni.
Ngaphezu kwalokho, ngokusebenza kweqhwa, inkinga yokuhlinzeka izitshalo ngomswakama entwasahlobo yaxazululeka, ngoba, njengoba wazi, iqhwa eliningi liyancipha, kuncipha kancane kancane. Ngakho-ke, inhlabathi engaphansi kwezihlahla zezithelo izoba nomswakama isikhathi eside, inhlabathi, njengokungathi kusuka ekuniseleni ngokudonsa, izothuliswa kancane kancane ngomswakama, bese kuthi uma iqhwa libukhali, iningi lomswakama livele lishintshe.
Kulokhu, mhlawumbe, wonke ama-plus avela ekuhlanganiseni kwengqimba yeqhwa elizungeze izihlahla zezithelo liphela. Manje sesithuthele ekamu lalabo balimi nabahlali basehlobo, kanye nabalimi abancane abenqabayo ukubumbanisa iqhwa ezingadini zabo ngokuphelele noma ngokwengxenye.
Ngabe kunjalo ngempela?
I-Physics ithi looser iqhwa (futhi hhayi elibi), okungcono ligcina ukushisa. Ngemuva kwalokho, iqhwa elixegayo liqoqo lezikhukhula zeqhwa, phakathi kwazo okuqongelela inani elikhulu lomoya, eligcina ukushisa emhlabathini.
Ngaphezu kwalokho, ubuningi beqhwa engadini, futhi kunoma yisiphi isivande, lihlala lilungile, le ngubo kanye nomcamelo ngasikhathi sinye. Isithwathwa asivumeli ungqimba lomhlabathi luvundle futhi lugcine ingxenye engezansi yesiqu, futhi kwesinye isikhathi amagatsha okuqala wamathambo kusuka ekuqandeni ebusika obunzima ikakhulukazi. Umgcini wegadi ngamunye uzokutshela ukuthi ungqimba lweqhwa likhulu, umhlabathi ungashoni.
Ungqimba olukhulu lweqhwa elixegayo, phakathi kokunye, lungakhuphula izinga lokushisa kwengqimba yenhlabathi futhi lusheshise nokuncibilikisa kwenhlabathi futhi lukufudumele entwasahlobo, okubalulekile emithini yezithelo.

Kusungulwe ngumbono wokuthi ubukhulu bekhephu ku-centimeter kwenyusa izinga lokushisa kwenhlabathi cishe ngesigamu sedigri. Noma, lapho ubukhulu bumbobo beqhwa bukhula, okukhulu kokusabela okuvikelayo kweqhwa kubanda, futhi izinga lokushisa kumhlabathi nalo lizoba ngaphezulu. Isibonelo, uma izinga lokushisa lomoya lingama-30 degrees ngaphansi kwe-zero futhi ubukhulu beqhwa bungamasentimitha angama-30, khona-ke kuzoba nokukhishwa okungathi sína, okungaba ngamadigri ayi-15 ngaphansi kwe-zero, ebusweni bomhlaba, kepha uma kuneqhwa eliningi, ngokwesibonelo, liphindwe kabili, lingabe seliphezulu kakhulu ngaphezulu kwenhlabathi. ukufudumala, okungukuthi, ngama-degrees of the frost angama-30 efanayo namasentimitha angama-60 eqhwa ebusweni benhlabathi kungaba nama-degrees ambalwa kuphela weqhwa.
Into ethokozisa kakhulu ukuthi uma iqhwa lifinyelela imitha, khona-ke inhlabathi engadini, ngokungafani nakho konke okulindelwe ngabasekeli bokuqanjwa kweqhwa elizungeze izihlahla, izoncibilika ngokuqondile ngenxa yokungafani kwezinga lokushisa endaweni yomhlabathi nangaphezulu, umphumela we "paning frying" udaliwe, indima edlalwa yinhlabathi. Iqhwa liyancibilika kulo, kunjalo, futhi ngaphansi kwethonya lokukhanya kwelanga, futhi, kodwa iqhwa elihlanganisiwe lihlala isikhathi eside kakhulu futhi inhlabathi ibibitheke ngaphansi kwayo - wonke umuntu angayihlola engadini yabo.
Ngaphezu kwalokho, amagundane - eqinisweni, ahamba buthule futhi ezindaweni ezivulekile, eqhutshwa yindlala, kwesinye isikhathi awanqobi ngisho namabanga anjalo. Labo abakholelwa ukuthi iqhwa lingahlanganiswa ngendlela yokuthi into efana nodonga oluvikelayo lwakhelwe amagundane ngephutha nangaphezulu - cabanga ngakho, amagundane ahlohla isihlahla, liyini iqhwa lakho elihlanganisiwe ngabo?
Ukufingqa
Ngakho-ke, uma ufuna ukugcina inhlabathi ifudumele futhi ivikele izitshalo, kufanele ungavumeli iqhwa, uma ufuna ukuvikela ingadi ngokususa “umgwaqo oneqhwa” wamagundane, kufanelekile. Uma ufuna ukugcina umswakama omkhulu esizeni, kepha ngasikhathi sinye ubambe ukufudumala kwenhlabathi izinsuku eziningana, noma ngisho isonto, khona-ke iqhwa elisendaweni kufanele lihlanganiswe, ikakhulukazi izihlahla ze-apula kunoma yisiphi isiphunzi, ngoba umuthi we-apula uvuka kamuva kunabanye ngokuhamba kwesikhathi, sacetshiswa umswakama, sibonga iqhwa elihlanganisiwe, futhi ekugcineni inhlabathi yashiswa yilanga.
Kepha isivuno sezithelo zamatshe esivula ukuqhakaza kuqala, kuyingozi ukucwebela iqhwa elizungeze lezi zihlahla: okokuqala, bayovuka elangeni ngaphambi kokuba inhlabathi igcwale ngaphansi kweqhwa elihlanganisiwe futhi ukuqalelwa kwe-banal kungaqala lapho isisindo esingaphezulu komhlaba sesiqala ukukhula nokukhula, futhi izimpande zisalokhu “zilala” emhlabathini obandayo, ngaphansi kweqhwa elinyathelwe phansi.
Isizathu sesibili sokungafuneki kwengqimba yeqhwa elizungeze izithelo zamatshe uzizwe e-cherry futhi ibhilikotsi, ngabo, umswakama obedlulele ozungeze intamo yezimpande, okuzokwenzeka ngempela (ngoba ngezinyawo zakho uzokwenza okuthile okunjengomgodi lapho kuzogeleza khona amanzi ancibilikayo), nakho kuyingozi futhi kungaholela ekuphanjukeni kwentamo yomsuka.
Ngokwami, umbono wami yilokhu - Ungavumela iqhwa engadini yezithelo ze-apula, enhlabathini enesihlabathi, ukuqoqa umswakama owengeziwe futhi uvikele nezitshalo ezitshalweni, kodwa kuphela uma uyisakhamuzi esifundeni esisenkabeni naseningizimu, lapho ubusika bungabandi kangako.
Bhala emazwini ukuthi ucabangani ngokunyathela iqhwa elizungeze izihlahla zezithelo?
