Kev hloov pauv mus ib ntus thiab tas mus li

Zoo Siab

• Piv txwv ntawm kev hloov pauv ntawm sab cev nqaij daim tawv
• Piv txwv ntawm kev hloov pauv mus tas li

Matter yog txhua yam uas nyob hauv qhov chaw, muaj qhov hnyav thiab uas tuaj yeem pom los ntawm kev nkag siab. Matter tuaj yeem hloov pauv. Cov no tuaj yeem yog lub cev, thaum teeb meem hloov pauv lub xeev (khoom, kua lossis roj) tab sis tswj hwm nws tus yam ntxwv; lossis tshuaj lom neeg, thaum tshuaj lom tshuaj hloov pauv cov khoom ntawm qhov teeb meem.

Kev hloov pauv lub cev feem ntau ua rau muaj kev hloov pauv ib ntus ntawm qhov teeb meem, thaum kev hloov tshuaj lom neeg yuav luag tas mus li.

• Kev hloov pauv ib ntus. Lawv tshwm sim thaum qhov teeb meem raug hloov pauv tab sis tom qab ntawd rov zoo nws thawj qhov xwm txheej. Cov no yog kev hloov pauv lub cev, tom qab qhov teeb meem tsis poob nws lub peev xwm thiab rov qab mus rau nws lub xeev qub. Piv txwv li: thaum cov dej khov yaj, nws rov mus rau nws cov kua theem yam tsis tau poob nws cov khoom. Cov kev hloov pauv no tuaj yeem tshwm sim los ntawm kev txhob txwm ua rau lub cev tshwm sim yam tsis tau xav txog (qhov xwm txheej tshwm sim thiab hloov pauv qhov xwm txheej ntawm lub cev).
• Kev hloov pauv mus tas li Lawv tshwm sim thaum thawj qhov xwm txheej ntawm qhov teeb meem raug hloov pauv. Tom qab qhov kev hloov pauv no, teeb meem tsis rov qab mus rau nws lub xeev qub. Lawv yog cov kev hloov pauv tsim los ntawm kev hloov tshuaj lom neeg uas ua rau hloov pauv tsis tau. Piv txwv li: decomposition zaub mov, oxidation, combustion.

Ua raws li:

• Lub cev hloov pauv
• Kev hloov tshuaj lom neeg
