- theoretical chemistry.
Tom qab ntawd, lo lus nug yog, cov ceg ntawm chemistry yog dab tsi?
Muaj ntau ceg ntawm chemistry lossis chemistry kev qhuab qhia. Tsib ceg tseem ceeb yog suav tias yog organic chemistry inorganic chemistry, analytical chemistry , lub cev chemistry , thiab biochemistry.
Puas yog pharmacology ib ceg ntawm chemistry?
Pharmacology – ceg ntawm cov tshuaj thiab biology cuam tshuam nrog kev kawm txog tshuaj yeeb yam nrog rau tshuaj teebmeem. Phytochemistry - kawm txog phytochemicals uas los ntawm cov nroj tsuag. Radiochemistry – chemistry ntawm cov khoom siv hluav taws xob.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Peb ceg loj hauv tsob ntoo ntawm txoj sia yog dab tsi?
Qhov no yuav pab peb txiav txim siab seb cov kab mob twg yuav tsum nyob ua ke ntawm tib 'txoj ceg' ntawm tsob ntoo ntawm txoj sia. Piv txwv li, tam sim no peb paub tias fungi muaj feem xyuam nrog cov tsiaj ntau dua li cov nroj tsuag. Siv cov cuab yeej no, tam sim no peb xav tias peb ceg tseem ceeb ntawm lub neej yog Archaea, Eubacteria, thiab Eukaryotes
Dab tsi yog 2 ceg tseem ceeb ntawm kev txheeb cais?
Ob ceg tseem ceeb ntawm kev txheeb cais yog piav qhia txheeb cais thiab inferential txheeb cais. Ob leeg ntawm no yog ua haujlwm nyob rau hauv kev tshawb fawb ntawm cov ntaub ntawv thiab ob qho tib si tseem ceeb rau cov tub ntxhais kawm ntawm kev txheeb cais
Sub ceg ntawm science yog dab tsi?
Peb ceg ntawm Science suav nrog Physical Science, Earth Science, thiab Life Science. Txhua ceg ntawm no muaj xws li ib tug xov tooj ntawm sub-branches. Physical Science suav nrog thaj chaw xws li Chemistry thiab Physics. Ntiaj teb Science suav nrog thaj chaw xws li Geology, Meteorology, thiab Astronomy
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
