Physics thiab chemistry yog kev kawm keeb kwm, kev qhia uas tsis xav txog yam tsis muaj duab siv, khoom siv hauv chaw kuaj thiab khoom siv ua qauv qhia. Tseeb tiag, txhawm rau kom cov tub ntxhais kawm ua tiav cov kev qhuab qhia no zoo, cov kws tsim nyog thiab cov kws paub dhau los yog qhov yuav tsum tau ua ua ntej. Txawm li cas los xij, nws yog ib qho tseem ceeb uas cov chav kawm txog physics thiab chemistry tau zoo nkauj thiab muaj cov khoom siv nrog txhua yam koj xav tau.
Yuav ua li cas npaj lub txee hluav taws xob
Thaum tsim cov chav kawm physics, ib tus yuav tsum ua raws li lub hauv paus ntsiab lus: "Muaj txhua yam koj xav tau thiab tsis muaj dab tsi ntxiv." Nws raug nquahu kom dai daim duab ntawm cov kws tshaj lij tshaj plaws ntawm cov ntsa, nrog cov lus qhia luv luv ntawm lawv qhov kev ua tau zoo tshaj plaws hauv kev tshawb fawb. Tsis tas li ntawm cov phab ntsa yuav tsum muab tso rau sawv ntsug nrog cov lus piav qhia txog qhov tshwm sim ntawm lub cev, cov kev cai yooj yim, cov ntawv tshaj tawm nrog cov qauv. Cov qauv ntawm ib qho khoom siv twg uas qhia pom kev txhim kho ntawm physics raws li kev tshawb fawb txij puag thaum ub los tsis cuam tshuam.
Piv txwv li, nws tuaj yeem ua qauv ntawm Archimedean ntsia hlau, lub tshuab muaj zog, Popov txais.
Nws yog qhov tseem ceeb heev uas nyob hauv chav tsev physics muaj chav kuaj teeb tsa ntawm cov khoom muaj feem rau txhua ntu ntawm physics - mechanics, thermodynamics, electrodynamics, optics, thiab lwm yam. Nws yog qhov tsim nyog uas tus kws qhia ntawv, thaum qhia txog qhov tshwm sim ntawm lub cev lossis txoj cai lij choj, tuaj yeem qhia nws cov lus tau meej. Nws tsis yog txhua qhov tsim nyog tias qhov no yog qhov khoom kim, tshwj xeeb yog vim tsis yog txhua lub tsev kawm ntawv tuaj yeem them taus. Qhov loj tshaj plaws yog tias nws yog qhov zoo, tso cai rau cov kev sim pom kom pom tseeb thiab ua tau raws li qhov xav tau ntawm kev nyab xeeb.
Kho kom zoo nkauj chav hauv tsev
Chemistry yog kev kawm uas lub luag haujlwm ntawm kev sim kom pom tshwj xeeb yog qhov tseem ceeb. Yog li, qhov tseem ceeb yuav tsum tau them nyiaj rau kom ntseeg tau tias chav sib tov muaj cov cuab yeej siv kuaj (ntsuas lub raj, raj dej, ntsuas iav, cawv teeb, pipettes, pam tuag, racks nrog tus tuav, thiab lwm yam). Reagents kuj tseem yuav tsum muaj: acids, alkalis, ntsev, qee cov hlau, halogens. Los ntawm cov khoom siv pom, cov rooj ntawv yog qhov tsim nyog tiag tiag: “Lub sij hawm muaj cov txheej txheem tshuaj lom neeg ntawm D. I. Mendeleev "(zoo dua rau qhov loj me nrog qhov ci zoo thiab pom qhov txawv ntawm cov tsiaj ntawv)," Ib tug xov tooj ntawm cov haujlwm hlau "," Solubility ntawm cov kua qaub, puag thiab ntsev nyob hauv dej."
Peb lub rooj no yog qhov xav tau yam tsawg kawg nkaus, uas yuav tsum tau nyob hauv chav qhia txog chemistry ntawm qhov chaw kawm txuj ci.
Cov rooj zaum uas qhia meej txog lub luag haujlwm ntawm kev coj khoom hauv lub neej niaj hnub no tau zoo rau cov neeg ua haujlwm no. Piv txwv li, koj tuaj yeem tso sawv ntsug uas yuav teev cov kev lag luam uas siv sulfuric acid - ib yam khoom uas muaj npe txaus siab rau lub npe tsis txaus siab ntawm "ntshav ntawm chemistry". Thaum tsim chav pleev tshuaj, yuav tsum tau them nyiaj tshwj xeeb rau cov cai kev nyab xeeb, piv txwv li, txhua qhov kua qaub yuav tsum tshem tawm ntawm cov menyuam yaus!
