Izibani zemoto ziyaguga

Izingxenye zesistimu kagesi wemoto zingaphansi kokuguga kancane kancane. Kwamanye amalambu okukhanya, izimpawu zokuguga eziqhubekayo zingabonakala ebusweni besibani sengilazi.

Ukuguga kancane kancane kwezibani kuwumphumela wezinqubo ze-thermochemical ezenzeka kuzo. Izintambo kuma-light bulb zenziwe nge-tungsten, insimbi enezinga eliphakeme kakhulu lokuncibilika elingaba ngu-3400 degrees Celsius. Kusibani sokukhanya esijwayelekile, ama-athomu ensimbi angawodwa ayagqashuka kuso lapho kubaswa umcu. Lesi simo sokuhwamuka kwama-athomu e-tungsten kubangela ukuthi umcu kancane ulahlekelwe ukushuba, wehlise isigaba sawo esiphambanayo esisebenzayo. Ngokulandelayo, ama-athomu e-tungsten ahlukanisiwe ku-filament ahlala endaweni engaphakathi yeflask yengilazi yeflask. Lapho benza imvula, ngenxa yokuthi isibani siba mnyama kancane kancane. Lokhu kuwuphawu lokuthi intambo isizosha. Kungcono ukuthi ungayilindeli, vele uyishintshe ufake entsha ngokushesha nje lapho uthola isibani esinjalo.

Izibani ze-halogen ziqinile kakhulu kunezivamile, kodwa azibonisi izimpawu zokugqoka. Ukuze kuncishiswe izinga lokuhwamuka kwama-athomu e-tungsten emculweni, agcwaliswa ngaphansi kwengcindezi ngegesi etholakala ku-bromine. Ngesikhathi sokukhanya kwe-filament, ingcindezi ngaphakathi kwe-flask iyanda izikhathi eziningana, okwenza kube nzima kakhulu ukukhishwa kwama-athomu e-tungsten. Lezo ezihwamukayo zisabela negesi ye-halogen. Ama-tungsten halides atholakalayo aphinde afakwe entanjeni. Ngenxa yalokho, amadiphozithi awakhi endaweni engaphakathi yeflask, okubonisa ukuthi intambo isizophela.
