Raws li ib txwm muaj, hlau hmoov tsis ignite tab sis undergoes oxidation nyob rau hauv cov huab cua. Txawm li cas los xij, muab cov xwm txheej zoo, nws yeej muaj peev xwm combust.
Noj, piv txwv, ib tug scenario qhov twg koj ignite ib tug beaker nrog 50% cawv. Yog hais tias koj qhia ib tug loj npaum li cas ntawm hlau hmoov, kub nws nyob rau hauv lub beaker, thiab tom qab ntawd faib nws raws lub beaker phab ntsa ntawm qhov deb ntawm ob mus rau kaum tsib centimeters, nws yuav taws. Qhov tseem ceeb, nanoscale hlau hmoov muaj peev xwm ntawm cov cua kub.
