Ib piv txwv yog Niagra Falls hydroelectric zog cog. Ib txhia ntawm cov dej uas ib txwm mus hla lub ntog yog channeled los ntawm ib tug turbine. Cov dej tig lub turbine (waterwheel) uas tig lub tshuab hluav taws xob, thiab tawm los ntawm hluav taws xob. Kuj tseem muaj ntau qhov loj dua piv txwv Piv txwv li, lub pas dej Grand Coulee.
Kuj paub, qee qhov piv txwv ntawm hydropower yog dab tsi?
Hydroelectric zog Lub Hwj Chim Lub Zog Cia Cov dej ntws nrawm no tig lub turbines, thiab lub tshuab hluav taws xob hloov lub zog kinetic no rau hauv hluav taws xob. Ib piv txwv ntawm a hydroelectric zog fais fab dam, yog Kielder Water reservoir, nyob rau hauv Northumberland, ua los ntawm RWE Npower thiab yog qhov loj tshaj plaws nyob rau hauv England.
Qhov thib ob, hom hluav taws xob twg yog hydropower? Hydroelectric zog yog lub zog tauj dua tshiab uas siv lub zog txav dej los tsim hluav taws xob . Cov txheej txheem hydroelectric pib ntev ua ntej koj tig koj lub teeb rau hauv tsev lossis ua haujlwm. Cov dej num loj loj feem ntau yog cov dams.
Raws li txoj cai, peb siv hydroelectric zog li cas hauv lub neej txhua hnub?
Ib tug thawj siv ntawm hydropower zog yog los tsim hluav taws xob. Cov khoom xyaw tseem ceeb ntawm hydroelectric zog fais fab nroj tsuag yog dams, dej ntws thiab turbines. Nroj tsuag siv dams los tsim reservoirs qhov twg cov dej khaws cia. Cov dej no yog tom qab ntawd tso tawm los ntawm turbines thiab spun los qhib cov tshuab hluav taws xob thiab tsim hluav taws xob.
Cov chaw twg siv hluav taws xob hydroelectric?
Ntau tshaj 150 lub teb chaws tsim ib co hydroelectricity, txawm hais tias nyob ib ncig ntawm 50% ntawm tag nrho cov hydro-power yog tsim los ntawm tsuas yog plaub lub teb chaws: Tuam Tshoj, Brazil, Canada, thiab Tebchaws Meskas . Tuam Tshoj yog nyob deb ntawm qhov loj tshaj plaws hydro-power tsim nyob rau hauv lub ntiaj teb no, raws li qhia nyob rau hauv daim duab hauv qab no.

Dab tsi yog qhov muaj zog thiab qaug zog acid piav nrog piv txwv?
Cov kua qaub muaj zog sib cais (sib cais) tag nrho hauv dej). Piv txwv li, HCl, cov kua qaub muaj zog yuav tawg mus rau H + thiab Cl-ions. Cov acids tsis muaj zog dissociate ib nrab hauv dej. Piv txwv li, HF, cov kua qaub tsis muaj zog, tsuas yog yuav muaj qee yam ntawm HF cov molecules sib cais thaum twg los tau
Dab tsi yog qhov piv txwv piv txwv hauv kev txheeb cais?
Nyob rau hauv kev txheeb cais, sampling bias yog ib tug bias nyob rau hauv uas ib tug piv txwv yog sau nyob rau hauv xws li ib tug txoj kev uas ib co tswv cuab ntawm cov neeg npaj muaj ib tug tsawg sampling probability tshaj lwm tus
Dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov?
Dab tsi yog qhov kawg ntawm lub zog rau yuav luag txhua yam kab mob tshwj tsis yog cov neeg nyob sib sib zog nqus hauv dej hiav txwv ze ntawm lub qhov cua sov? Qhov kawg qhov chaw yuav yog lub hnub
Piv txwv li, muaj zog acid thiab qaug zog acid yog dab tsi?
Piv txwv ntawm cov acids muaj zog yog hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) thiab sulfuric acid (H2SO4). Cov kua qaub tsis muaj zog tsuas yog qee qhov sib cais, nrog rau ob qho tib si undissociated acid thiab nws cov khoom dissociation tam sim no, nyob rau hauv kev daws, nyob rau hauv equilibrium nrog ib leeg
Vim li cas cov duab ntawm titration nkhaus txawv rau titration ntawm muaj zog acid vs muaj zog puag thiab qaug zog acid vs muaj zog puag?
Cov duab dav dav ntawm titration nkhaus yog tib yam, tab sis pH ntawm qhov sib npaug sib txawv. Hauv qhov tsis muaj zog acid-muaj zog titration, pH yog ntau dua 7 ntawm qhov sib npaug. Hauv qhov muaj zog acid-tsis muaj zog titration, pH tsawg dua 7 ntawm qhov sib npaug
