Utwaramuriro

Utwaramuriro (kuturikira pyrophoricity muChingezi) zvinoreva chinhu chinoyerekana chapfuta moto choga mumhepo pasi pe54^oC kana chinopfuta mukati memamineti mashanu (5mins) mushure mekunge chaiswa mumhepo. Mitombo ine utwaramuriro inosanganisira iron sulphide nesimbi dzinoti plutonium neUranium dzinopfuta dzega kana dziri paudha kana dzakavedzengwa kuita nhete.

Izwi rokuti pyrophoricity rine zvikamu zviviri zvinoti: pyro kureva moto uye phoric kureva kutakura. Saka kuChiShona tatora mazwi maviri anoti kutwara kureva kutakura uye muriro kureva moto.

Magwenya emoto anoshandisa simbi dzine utwaramuriro - ferrocerium muenzaniso wesimbi inoshanda nemutowo uyu.
