Chemistry ua tau pab peb to taub, saib xyuas, tiv thaiv thiab txhim kho cov ib puag ncig ncig. Chemists tab tom tsim cov cuab yeej thiab cov txheej txheem rau ua paub meej tias peb tuaj yeem pom thiab ntsuas huab cua thiab dej paug. Lawv tau pab tsim cov pov thawj uas qhia tau hais tias peb cov huab cua hloov pauv li cas rau lub sijhawm.
Yog li ntawd, vim li cas peb thiaj tiv thaiv ib puag ncig?
Kev tiv thaiv ib puag ncig yog kev xyaum ntawm tiv thaiv lub ntuj ib puag ncig los ntawm cov tib neeg, cov koom haum thiab tsoomfwv. Nws lub hom phiaj yog rau cov kev pab cuam conservenatural thiab lub ntuj uas twb muaj lawm ib puag ncig thiab, yog tias ua tau, kho kev puas tsuaj thiab thim rov qab.
Qhov thib ob, cov kws kho mob pab cov kws kho mob kho cov neeg mob li cas? Chemistry muab cov tshuaj, khoom siv, thiab technology uas kws kho mob siv rau kho lawv cov neeg mob . Chemists pab txhawm rau txhim kho cov qoob loo ntau dua thiab muaj kev nyab xeeb dua, muaj txiaj ntsig zoo los tiv thaiv cov qoob loo. Tshuaj pab txhawm rau txheeb xyuas cov pa phem thiab tiv thaiv kev ua qias tuaj. Piav ob txoj kev ntawd kws tshuaj kawm lub qab ntuj khwb.
Tib neeg kuj nug, koj tuaj yeem pab txhawb kev tiv thaiv ib puag ncig li cas?

Dab tsi yog qhov tseem ceeb ntawm chemistry?
Chemistry yog tseem ceeb vim txhua yam koj ua yog chemistry ! Txawm koj lub cev yog tsim los ntawm cov tshuaj. Tshuaj Kev tshwm sim tshwm sim thaum koj ua pa, noj, lossis tsuas yog zaum nyeem ntawv. Tag nrho cov teeb meem yog tsim los ntawm cov tshuaj, yog li cov qhov tseem ceeb ntawm chemistry yog tias nws yog kev kawm ntawm txhua yam.
