Teb thiab piav qhia: Flammability yog a chemical khoom , los yog ib qho uas tuaj yeem pom thaum cov khoom hloov pauv mus rau lwm yam. Rau piv txwv , ntawv yog nplaim taws.
Ua li no, puas yog flammable ib yam tshuaj los yog lub cev?
Flammability yog a chemical khoom vim combustion a tshuaj hloov . A tshuaj hloov yog ib tug txheej txheem uas ib los yog ntau yam tshuaj hloov dua siab tshiab rau hauv ib los yog ntau tshaj cov khoom tshiab nrog txawv khoom . Roj av yog heev nplaim taws . Flammability yog ib qho kev ntsuas uas yooj yim npaum li cas yuav hlawv.
Ib yam li ntawd, 5 cov khoom siv tshuaj lom neeg yog dab tsi? Nov yog qee qhov piv txwv ntawm cov khoom siv tshuaj lom neeg:
- Reactivity nrog lwm yam tshuaj.
- Toxicity.
- Coordination tooj.
- Flammability.
- Enthalpy ntawm kev tsim.
- Kub ntawm combustion.
- Oxidation xeev.
- Tshuaj stability.
Ib yam li ntawd, tej zaum koj yuav nug tias, piv txwv li cas ntawm lub cev khoom?
Piv txwv ntawm lub cev muaj zog yog: xim, tsis hnov tsw, khov point, boiling point, melting point, infrared spectrum, attraction (paramagnetic) los yog repulsion (diamagnetic) rau hlau nplaum, opacity, viscosity thiab ceev. Qhov ntau khoom peb tuaj yeem txheeb xyuas cov khoom, qhov zoo dua peb paub qhov xwm txheej ntawm cov khoom ntawd.
4 piv txwv ntawm cov khoom siv tshuaj lom neeg yog dab tsi?
Piv txwv ntawm tshuaj muaj zog suav nrog flammability, toxicity, tshuaj stability, thiab kub ntawm combustion. Cov khoom siv tshuaj yog siv los tsim tshuaj kev faib tawm, uas yog siv rau hauv daim ntawv lo ntawm cov thawv ntim khoom thiab chaw cia khoom.

Puas yog lub zog uas taug kev los ntawm hluav taws xob Ib qho piv txwv ntawm qhov no yog lub teeb?
2) Lub teeb yog cais raws li Electromabnerle RADIATION vim hluav taws xob thiab sib nqus teb vibrate nyob rau hauv lub teeb yoj. RADIANT ENERGY - yog lub zog uas taug kev los ntawm hluav taws xob. Ib qho piv txwv ntawm qhov no yog lub teeb. 4) Cov hluav taws xob cua sov, tseem hu ua _INFRARED WAVES w tsis tuaj yeem pom ntawm koj lub qhov muag tab sis tuaj yeem hnov ntawm koj cov tawv nqaij
Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
Thaum lub ntim ntawm ib qho piv txwv ntawm cov pa roj yog txo lub siab ntawm cov qauv ntawm cov pa roj?
Kev txo qis Cov pa roj sib xyaw txoj cai hais tias lub siab ntawm cov pa roj yog inversely cuam tshuam nrog lub ntim thiab ncaj qha ntsig txog qhov kub thiab txias. Yog tias qhov kub thiab txias yog nyob tas li, qhov sib npaug raug txo rau Boyle txoj cai. Yog li ntawd, yog tias koj txo qhov siab ntawm cov roj av tas li, nws qhov ntim yuav nce ntxiv
Dab tsi yog qhov tseeb ntawm lub cev lub cev lub cev kev xav xav?
Lub cev lub cev lub ntsiab lus kev xav (PSSH) yog ib txoj hauj lwm hauv lub tswv yim ntawm kev txawj ntse tsim los ntawm Allen Newell thiab Herbert A. 'Ib lub cim lub cev muaj qhov tsim nyog thiab txaus txhais tau tias rau kev ua haujlwm ntse.'
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
