Amava Chemical - Mount ntshava phezu kwetafile

Indlela ukuba bachitha isifundo yokonwabisa chemistry ekhitshini kwaye sikhuselekile yaye kumnandi umntwana wakho? Sizama ukubamba amava yemichiza real - mlilo kwi plate itafile rhoqo. Kuba oku, kufuneka ezi zibonelelo zilandelayo neekhemikhali:

- intwana ngodongwe (kuzo siya kwenza le mlilo ngokwawo);

- ipleyiti;

- acetic acid;

- baking soda;

- lolwelo lwesicocisi sokuhlamba;

- idayi.

Awona macandelo ingentla ngokulula afumaneka kuyo yonke imizi okanye kwisebe kwezoqoqosho wevenkile ekufuphi. Ba uphephile, kodwa njengayo nayiphi amalinge chemistry, oku kuza kufuna nokuba ukuthotyelwa imithetho yokhuseleko.

nenkcazo yomsebenzi:

1. Lom- kwaye wenze isiseko cone mlilo kunye emngxunyeni. Ixhume kuwo ngohlangothi ngempama ngononophelo. Sifumana yokudlala mlilo ubeko ukuya kumathambeka. ubungakanani engaphakathi loyilo lwethu kufuneka sibe isangqa enobubanzi ezimalunga ne-100 - mm 200. Ngaphambi kokufaka ubeko epleyitini okanye itreyi khangela mlilo yethu evuzayo, siqokelela ngamanzi ubone ukuba udlula kuyo. Ukuba yonke into ilungile - ukuseta ukuma kwalo mlilo kwi nembasa.
2. Ngoku ugqithele inxalenye elandelayo - upheka mlilo. Silala kwi mlilo yethu bahleka ngodongwe enye icephe nesoda yokubhaka, lwesicocisi sokuhlamba ulwelo umthamo efanayo kunye idayi ukuba angcolise ubungangamsha mlilo elizayo, udaka kwi ehambelana umbala lokwenene. Ukuphumeza ukufana eliphezulu, ungasebenzisa umbala ukutya, ipeyinti abantwana ukupeyinta kwaye nkqu juice beetroot zesiqhelo. Le imichiza kukuba lokuphinda amava umntwana emehlweni ukujaduka kuthe mlilo yendalo.
3. Ukuqalisa ukujaduka kuyimfuneko ukuba bazalise umngxuma-sesine ikomityi iviniga. Ngexesha indlela imichiza yikhompawundi yesoda kunye acetic acid ikhokelela ukuyilwa neetyuwa ze asidi, leyo inxulumene khompawundi ezingazinzanga kwaoko abole kwamanzi kunye carbon dioxide. Yiyo le yinkqubo isiponji ukunika umbono wethu we-dubulo lo mlilo kunye udaka kumathambeka. Imichiza amava epheleleyo.

Umboniso mlilo esebenzayo esikolweni

Ukongeza uhlobo echazwe ngentla-of kukubonakalisa mlilo ekhuselekileyo, kusekho ezininzi iindlela ukufumana mlilo phezu kwetafile. Kodwa ezi experimenti kwenziwa ngcono kwizakhiwo elungiselelwe ngokukodwa - iilebhu chemistry yesikolo. Eyona kakuhle ngabo bonke Volcano esikolweni Boettger. Zokuziphatha efunekayo ammonium dichromate, eliphalala induli, kwi phezulu lokungahlangani yayo. Le ndawo ibekwe isiqwenga yomqhaphu zifakwe utywala, nto leyo ebangele. Ngexesha indlela nitrogen, amanzi kunye chromium oxide. Indlela abasabela wabe efana kakhulu yakhokelela kuqhambuko mlilo esebenzayo.

Ukuze ngentloko, ngokunjalo nophuhliso ngokwezifundo ebantwaneni oludityaniswe kakuhle eksperimenti imichiza ethile Xikombiso lexi tivekaka ngopfu i mlilo kwimbali lasisiseko senkcubeko yoluntu, umzekelo, kunye dubulo kwiNtaba iVesuvius eItali, ingakumbi ngenxa yalo enhle kwaye ukuze kuxhamle kolundi Makhe yakhiwe lukhulu ukupeyinta Karla Bryullova "iintsuku Last sePompeii" (1827-1833 biennium).

Ngaphandle wenzala abantwana uza kuba ibali umsebenzi mlilo kunokuba onge nobanelisayo. Ezi ngcali basoko belwakhele umkhanya sele extinct kunye mlilo namhlanje, benze iingqikelelo malunga nexesha kunokwenzeka kunye namandla kuqhume elizayo.
