Qhov tshwm sim ntawm kev siv ntau dhau zog yog nce nqi rau koj . Qhov no tuaj yeem tuaj rau hauv daim ntawv ntawm cov roj thiab zog cov nqi; koj yuav tau them ntau dua yam tsis muaj txiaj ntsig rov qab los ntawm koj cov peev txheej. Koj kuj tseem yuav ua rau txo qis kev cia siab lub neej ntawm cov cuab yeej siv thiab lwm yam khoom siv hluav taws xob.
Khaws qhov no saib, vim li cas nws thiaj phem rau nkim lub zog?
nkim zog tsis zoo rau ib puag ncig thiab. Ntau ntawm cov zog qhov chaw peb nyob ntawm, xws li cov thee thiab cov nkev, tsis tuaj yeem hloov tau - ib zaug peb siv lawv, lawv ploj mus ib txhis. Lwm qhov teeb meem yog tias feem ntau ntawm cov ntawv zog tuaj yeem ua rau muaj kuab paug.
Qhov thib ob, dab tsi yog qee txoj hauv kev uas lub zog poob qis? 10 Lub Zog Loj Tshaj Plaws Nyob Hauv Tsev
- Tawm Lub Teeb Rau.
- Siv Cov Qub Incandescent.
- Tawm Hauv Hluav Taws Xob Hluav Taws Xob.
- Ua kom lub Freezer Chest Freezer.
- Tshawb nrhiav koj lub tub yees.
- Khiav lub tshuab ntxuav tais diav Half-Full.
- Ntxuav Khaub Ncaws Hauv Dej Kub.
- Teeb lub ntsuas sov siab dhau.
Ntawm no, hluav taws xob puas tuaj yeem nkim?
Nkim hluav taws xob yog ua tau hauv qhov kev nkag siab tias hwj chim raug tsim tawm tsis tau siv rau ib yam dab tsi muaj txiaj ntsig. Piv txwv li, koj lub teeb. Lub teeb pom kev yog ua kom ua ib yam, ua kom pom kev. Ib qho ntxiv hwj chim siv uas tsis tau hloov dua siab tshiab rau pom lub teeb yog khib.
Dab tsi nkim lub zog tshaj plaws?
Nov yog yam uas siv lub zog tshaj plaws hauv koj lub tsev:
- Cua txias thiab cua sov: 47% ntawm kev siv zog.
- Dej rhaub: 14% ntawm kev siv hluav taws xob.
- Tshuab ntxhua khaub ncaws thiab tshuab ziab khaub ncaws: 13% kev siv hluav taws xob.
- Teeb pom kev zoo: 12% ntawm kev siv hluav taws xob.
- Tub yees: 4% ntawm kev siv hluav taws xob.
- Fais qhov cub: 3-4% ntawm kev siv hluav taws xob.
- TV, DVD, lub thawv cable: 3% ntawm kev siv zog.
- Tshuab ntxuav tais diav: 2% ntawm kev siv hluav taws xob.

Koj yuav txiav txim siab li cas yog tias cov kua qaub muaj zog lossis tsis muaj zog?
Yog hais tias ib qho acid tsis tau teev tseg ntawm no, nws yog ib qho tsis muaj zog acid. Nws tuaj yeem yog 1% ionized lossis 99% ionized, tab sis nws tseem raug cais raws li cov kua qaub tsis muaj zog. Txhua cov kua qaub uas dissociates 100% rau hauv ions yog hu ua ib tug muaj zog acid. Yog hais tias nws tsis dissociate 100%, nws yog ib tug qaug zog acid
Txoj cai twg yog txhawm rau muab lub zog saib xyuas muaj zog ntxiv dag zog rau kev ua txhaum cai lij choj tiv thaiv kev ua phem thiab tiv thaiv kev lag luam nyiaj txiag?
COV PHOOJ YWG ACT TEEV NTUJ TEEB MEEM NTAWM TXOJ CAI TXOJ CAI TSHIAB
Yuav ua li cas tshwm sim thaum koj titrate ib tug muaj zog acid nrog ib tug muaj zog puag?
Lub hom phiaj ntawm lub zog acid-muaj zog hauv paus titration yog los txiav txim siab qhov concentration ntawm acidic tov los ntawm titrating nws nrog ib tug yooj yim tov ntawm paub concentration, los yog vice versa, kom txog thaum neutralization tshwm sim. Yog li ntawd, cov tshuaj tiv thaiv ntawm cov kua qaub thiab lub hauv paus muaj zog yuav ua rau dej thiab ntsev
Koj yuav ua li cas ntxiv dag zog rau hauv pem teb tsis muaj zog?
Txhim kho bouncy pem teb los ntawm kev ntxiv bridging, ntxiv ib txheej ntawm plywood los yog ntxiv ib phab ntsa los yog beam. Peb mam li qhia koj peb txoj kev stiffen li koj co nto pem teb los ntawm kev ntxiv Bridging, txhim kho plywood raws joists thiab ntxiv ib lub phab ntsa los yog nqaj nyob hauv pem teb. Ib qho ntawm peb tuaj yeem daws koj qhov teeb meem, nyob ntawm koj qhov xwm txheej
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
