Mazano kuona sei sirivha kumba

Science uyu ano zera muzvigadzirwa mberi asingarambi mirai, nekuti zuva kuumba itsva uye nzira itsva vaswedere nokuda kwevanhu rose uye yakananga vanhu zvikurukuru, kusanganisira kwete zvikuru cleanly achirifananidza ukama mutemo uye hana - fraudsters vachitengesa sirivha, sirivha-kuifukidza uye akaita "munhu sirivha" zvishongo. Kuti varege kuva avo vakatambudzwa, zvakakodzera kushandisa kuminamato unyanzvi, kana kanenge kuziva sei kuziva sirivha kumba. Uye zvichava yakatsaurirwa nyaya yedu.

Chokutanga, unofanira kuziva ehupfumi kwemashoko iyo vakadzi uye dzevanhu zvishongo. Silver - vanokudzwa simbi kuva mukuru chafariz conductivity ehupfumi, zvakanaka vanobwembura uye magnets a. Kuziva izvi, tinogona kupa wandei nzira kuziva sei sirivha pamusha:

1. zvishongo chindori sirivha Forogo, Banga Nechipunu mano kushandisa maoko kudziya nyore, uye kana chimwe chikamu chigadzirwa ndokunyika mumvura inopisa nokukurumidza zvose zvinova sezvo inopisa sezvo mvura;
2. kana pachena kuti zvibereko chipo sirivha magineti, icharamba nhema panzvimbo yayo, nekuti zvinokosha nesimbi magnetization hakusi chaiyo;
3. nzira yechitatu inobatana zviyero yokunyanyisa mhando risina yokukurumidzira zviri nani kwete kushandisa - sezvo anodzivisa nyepera nendarira, zvinobikwa sirivha chaiye anogona hwakakungwa.

Uyezve, pane nzira dzakawanda kuti kuziva sei sirivha pamba, akadai:

1. varikwizire sirivha mumaoko avo - kana chigadzirwa hunosiya mavanga, ipapo rine zingi, iyo inoratidza kbps simbi;
2. vanga tsono - kana nemasiraidhi sirivha, baring nheyo imwe simbi, ipapo pamberi penyu nyepera;
3. kwiza choko - pashure kuonana kuti sirivha anotanga blacken choko (kusashanda nesirivha uye zvinhu);
4. kuzodza sulfuric mafuta kutengeswa chero chemishonga - zvino neVadzidzi sirivha pfumbu rima (sezvo muzvirevo nyaya, anogona kushanda kunyange apo nyaya kungoti sirivha). Ruvara ipfupi nyaya pashure kufashaira pasoda mhinduro ine chimedu aruminiyamu foil;
5. kuchadonha ayodhini - uchikurukura naye sirivha inotenderera dema, ari kumusoro mharidzo, maitiro kunoitika nokukurumidza. Chimwe chinhu ndechokuti dema haasi dzakwidzwa kushambidzwa kure;
6. bvunzo makemikari maitiro - kuchadonha nitric acid, uye ipapo kusiyira yakafanana munyu, zvichiguma donhwe vanofanira kuonekwa curdy precipitate zvesirivha chloride (kuonekwa pasi rinokudza girazi). Kana crystalline precipitate, ipapo isu kutungamirira chloride, uye nyaya Kunyepa.

Vamwe vanhu vanokwanisa kuziva munhuwi sirivha, asi ikozvino nzira iyi vanofanira kuvimba zvishoma uye zvishoma, nokuti yeshoko simbi anogona vasiyana chigadzirwa pakubika.

Takakurukura Zvisinei, zvokusarudza vanoverengeka kuziva sei sirivha kumba, mumwe nomumwe nzira idzi vanobvumira vamwe zvikanganiso, kunyanya kana vari kushandisa munhuwo zvake. Saka, kuti tizive unhu dzokuenzanisira nesirivha zano kuti zivisai kushandiswa zvishongo chitoro kana the pawn chitoro, apo kaduku muripo iwe uchapa mhinduro chaiwo kumubvunzo kana chigadzirwa iri sirivha, sirivha kuifukidza kana nyepera.
