Yuav ua li cas tus nqi thiab cov pawg ntawm a neutron piv mus rau nqi thiab loj ntawm ib tug proton ? Lawv pawg yog ze li sib npaug, tab sis protons muaj qhov zoo nqi thiab neutrons muaj qhov nruab nrab nqi . Yog tias koj plam electron ces koj yog sab laug nrog ntau qhov zoo nqi tshaj qhov tsis zoo nqi.
Ua raws li qhov kev pom no, qhov loj ntawm proton thiab neutron piv li cas?
Cov pawg ntawm a neutron yog me ntsis ntau dua cov loj ntawm ib tug proton , uas yog 1 atomic pawg unit (muas). (Ib atomic pawg unit sib npaug li 1.67 × 10−27 kg.) A neutron kuj muaj txog tib txoj kab uas hla li a proton , los yog 1.7 × 10-15 meters.
Ib yam li ntawd, qhov loj ntawm electron thiab proton yog dab tsi? Nuclear Binding Zog thiab pawg tsis xws luag
| Particle | Qhov hnyav (kg) | Mass (Mev/c2) |
|---|---|---|
| 1 atomic mass unit | 1.660540 x 10-27 kg | 931.5 MeV/c2 |
| neutron | 1.674929 x 10-27 kg | 939.57 MeV/c2 |
| proton | 1.672623x10-27 kg | 938.28 MeV/c2 |
| hluav taws xob | 9.109390x 10-31 kg | 0.511 MeV/c2 |
Thiab cov lus nug yog, dab tsi yog tus nqi thiab qhov loj ntawm proton?
A proton yog ib tug subatomic particle nrog ib tug zoo hluav taws xob nqi . Protons muaj nyob rau hauv lub nucleus ntawm txhua lub atom tab sis kuj tuaj yeem pom nyob deb ntawm lub nucleus, feem ntau yog ionized hydrogen. A proton muaj ib nqi ntawm +1, lossis 1e, uas yog sib npaug rau 1.602 x 10^-19 coulombs, thiab a pawg 1.67 x 10^-27 kg.
Yog vim li cas tus nqi rau huab hwm coj piv ntawm ib tug proton txawv?
Yog vim li cas nqi ntawm loj ratio ntawm ib qho hluav taws xob tib yam tsis hais txog ntawm cov roj noj hauv lub raj thaum lub nqi ntawm loj ratio yog txawv rau protons ? Yog li ntawd rau txawv gases lawv cov nuclei sib thooj yuav muaj txawv tus naj npawb ntawm neutrons yog li ntawd piv hloov mus ua txawv.

Dab tsi yog qhov txawv ntawm ib puag ncig lapse tus nqi thiab adiabatic lapse tus nqi?
A. Ib puag ncig lapse tus nqi yog hais txog qhov kub thiab txias nrog nce qhov siab hauv troposphere; uas yog qhov kub ntawm ib puag ncig ntawm qhov chaw sib txawv. Nws implies tsis muaj huab cua txav. Adiabatic txias tsuas yog cuam tshuam nrog huab cua ascending, uas txias los ntawm kev nthuav dav
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Dab tsi yog qhov txawv ntawm qhov ratio ntawm qhov ratio thiab tus nqi?
Ib qho piv txwv piv qhov loj ntawm ob qhov ntau. Thaum qhov ntau muaj qhov sib txawv, ces qhov piv yog hu ua tus nqi. Ib qho piv txwv yog ib nqe lus hais txog kev sib npaug ntawm ob qho piv txwv
Txhais li cas los ntawm tus nqi ntws ntawm tus nqi hluav taws xob?
