Cov tshuaj tiv thaiv huab cua tseem ceeb rau kev tshawb fawb forensic thiab tshwj xeeb rau kev tshawb nrhiav hluav taws thiab tawg. Thaum cov tshuaj tiv thaiv yuav tsum tau cua sov (tshwj tsis yog tsim nws) thiab ua rau kom txias nyob ib puag ncig, nws yog conversely hu ua endothermic. … Hluav taws kub yog ib qho tshuaj tiv thaiv exothermic uas tshwm sim sai dua.
Puas yog cov tshuaj tiv thaiv exothermic muaj txiaj ntsig?
Cov tshuaj tiv thaiv kab mob kub hnyiab tau muaj txiaj ntsig zoo vim lawv yog feem ntau yog siv los tsim hluav taws xob hluav taws xob, lossis siv hauv cov chaw lag luam kom ua tiav qee yam txheej txheem….
Vim li cas peb thiaj siv cov tshuaj tiv thaiv kab mob endothermic?
Endothermic reactions
Cov no yog cov tshuaj tiv thaiv uas noj lub zog los ntawm ib puag ncig (ie lub zog nkag mus rau cov tshuaj tiv thaiv, uas yuav pab koj nco txog lub npe endothermic). Lub zog feem ntau yog hloov pauv raws li lub zog cua sov, ua rau cov tshuaj tiv thaiv sib xyaw thiab nws ib puag ncig ua kom txias dua.
Ib qho piv txwv ntawm cov tshuaj tiv thaiv exothermic hauv lub neej txhua hnub yog dab tsi?
txhuam koj cov hniav, ntxuav koj cov plaub hau, thiab teeb koj lub qhov cub yog txhua yam piv txwv ntawm kev tawm tsam sab nraud. Nyeem ntawv kom paub txog kev sib txuas, nruab nrab, kev txhim kho corrosion, thiab dej-raws li exothermic tshua.
Yuav ua li cas yog 2 piv txwv ntawm exothermic tshua?
Ntawm no yog qee qhov piv txwv ntawm cov tshuaj tiv thaiv exothermic:
- Kev ua ib lub thawv dej khov. Ua cov dej khov nab kuab yog txheej txheem ntawm cov kua hloov nws lub xeev mus rau cov khoom. …
- daus tsim hauv huab. …
- Kub tswm ciab. …
- Xov tooj cua. …
- Kub qab zib. …
- Tsim cov ion khub. …
- Reaction ntawm Cov kua qaub thiab dej. …
- Dej thiab calcium chloride.
