Lub ntsiab txhais ntawm zaus yog ib yam dab tsi tshwm sim ntau zaus. Ib piv txwv ntawm zaus yog ib tug neeg ntsais qhov muag 47 zaug hauv ib feeb. YourDictionary txhais thiab siv piv txwv.
Kuj nug tias, piv txwv ntawm zaus hauv kev tshawb fawb yog dab tsi?
Nyob rau hauv qhov kev nkag siab tshaj plaws, zaus yog txhais raws li tus naj npawb ntawm lub sij hawm ib qho kev tshwm sim tshwm sim ib unit ntawm lub sij hawm. Hauv physics thiab chemistry, lub sij hawm zaus feem ntau yog siv rau nthwv dej, suav nrog lub teeb, suab, thiab xov tooj cua. Ntau zaus yog tus naj npawb ntawm lub sij hawm ib tug taw tes ntawm ib tug nthwv dej dhau ib tug taag reference point nyob rau hauv ib tug thib ob.
Ib tug kuj yuav nug, lo lus zaus yog dab tsi? zaus . Nyob rau hauv physics, tus naj npawb ntawm crests ntawm ib tug nthwv dej uas txav dhau ib qho taw tes rau hauv ib chav tsev ntawm lub sij hawm. Qhov feem ntau unit ntawm zaus yog tus hertz (Hz), sib raug rau ib crest ib ob. Cov zaus ntawm ib nthwv dej tuaj yeem xam los ntawm kev faib qhov nrawm ntawm nthwv dej los ntawm lub wavelength.
Ua li no, dab tsi yog ib qho piv txwv ntawm zaus?
Ntau zaus cov ntaub ntawv yog cov uas sawv cev ntau npaum li cas ib yam dab tsi tau pom. Rau piv txwv , koj tuaj yeem suav pes tsawg tus neeg hauv chav kawm hnav lossis tsis hnav tsho. Tsis yog - zaus cov ntaub ntawv tsis sawv cev ntau npaum li cas qee yam tau pom. Rau piv txwv , koj tuaj yeem ntsuas qhov siab ntawm cov neeg hauv chav kawm.
Koj nrhiav tau qhov zaus li cas?
A zaus yog tus naj npawb ntawm lub sij hawm cov ntaub ntawv muaj nqis tshwm sim. Piv txwv li, yog tias kaum tus tub ntxhais kawm tau qhab nia 80 hauv kev txheeb cais, ces tus qhab nia ntawm 80 muaj a zaus ntawm 10. Ntau zaus feem ntau sawv cev los ntawm tsab ntawv f. A zaus daim ntawv qhia yog tsim los ntawm kev npaj cov ntaub ntawv muaj nuj nqis nyob rau hauv ascending order of magnitude nrog rau lawv zaus.

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
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
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
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
