A chemical khoom yog ib tug yam ntxwv uas tsuas yog ntsuas los ntawm kev hloov ib yam khoom tshuaj tus kheej. A chemical khoom tsis tuaj yeem tsim los ntawm kev kov lossis saib cov khoom. Yuav tsum muaj ib tshuaj hloov mus pom nws! Qee qhov piv txwv yog: flammability, pH , thiab reactivity nrog dej los yog acid.

Ntawm no, puas yog radioactivity yog tshuaj lom neeg lossis lub cev?

Piv txwv ntawm tshuaj muaj zog yog kub ntawm combustion, flammability, toxicity, thiab lwm yam A khoom ntiag tug , ntawm qhov tod tes, yog ib yam uas tuaj yeem ntsuas lossis ntsuas tau, yam tsis muaj kev hloov pauv ntawm qhov teeb meem. Thiab li no los ntawm kev txhais ntawm tshuaj thiab lub cev muaj zog , radioactivity yog a chemical khoom.

Tsis tas li, qhov ntom ntom puas yog cov khoom siv tshuaj lom neeg lossis lub cev? A khoom ntiag tug yog ib tug yam ntxwv ntawm ib yam khoom uas yuav raug soj ntsuam los yog ntsuas yam tsis tau hloov tus kheej ntawm cov khoom. Lub cev muaj zog suav nrog xim, ceev , hardness, thiab melting thiab boiling ntsiab lus. A chemical khoom piav txog lub peev xwm ntawm ib yam khoom mus rau ib qho tshwj xeeb tshuaj hloov.

Hauv qhov no, xim puas yog lub cev lossis tshuaj lom neeg?

Xim . Kev hloov ntawm xim ntawm ib yam khoom tsis tas yuav yog qhov taw qhia ntawm a tshuaj hloov. Piv txwv li, hloov cov xim ntawm ib tug hlau tsis hloov nws lub cev muaj zog . Txawm li cas los xij, hauv a tshuaj tshuaj tiv thaiv, a xim Kev hloov pauv feem ntau yog qhov qhia tau tias muaj qhov tshwm sim tshwm sim.

Dab tsi yog qhov txawv ntawm cov khoom siv tshuaj thiab lub cev?

Lub cev muaj zog tuaj yeem soj ntsuam lossis ntsuas yam tsis hloov qhov muaj pes tsawg leeg. Lub cev muaj zog yog siv los soj ntsuam thiab piav txog qhov teeb meem. Cov khoom siv tshuaj tsuas yog pom thaum lub sijhawm a tshuaj cov tshuaj tiv thaiv thiab yog li hloov cov tshuaj tshuaj muaj pes tsawg leeg.
