Txoj Cai Kev Txiaj Ntsig ntawm Cov Teeb Meem tuaj yeem hloov pauv daim ntawv los ntawm kev hloov pauv ntawm lub cev thiab tshuaj lom neeg, tab sis dhau los ntawm ib qho ntawm cov kev hloov no, teeb meem tau khaws cia. Tib yam ntawm cov teeb meem tshwm sim ua ntej thiab tom qab qhov kev hloov pauv-tsis muaj qhov tsim lossis rhuav tshem.
Leej twg hais tias teeb meem Tsis tuaj yeem tsim lossis rhuav tshem?
Antoine LavoisierA portrait ntawm Antoine Lavoisier, tus kws tshawb fawb tau lees paub nrog kev tshawb pom ntawm txoj cai ntawm kev txuag ntawm huab hwm coj. Txoj cai lij choj no tau hais tias, txawm tias muaj tshuaj lom neeg lossis hloov pauv lub cev, huab hwm coj tau khaws cia - uas yog, nws tsis tuaj yeem tsim lossis rhuav tshem - hauv ib qho kev sib cais.
txhais li cas ntawm nqe lus teeb meem Tsis tuaj yeem tsim lossis rhuav tshem?
Yooj yim hais, txoj cai kev txuag ntawm pawg txhais tau tias teeb meem tsis tuaj yeem tsim lossis rhuav tshem, tab sis nws tuaj yeem hloov cov ntaub ntawv. Nyob rau hauv chemistry, txoj cai yog siv los sib npaug tshuaj sib npaug. Tus naj npawb thiab hom atoms yuav tsum yog tib yam rau ob qho tib si reactants thiab cov khoom.
Vim li cas lub zog tsis tuaj yeem tsim lossis rhuav tshem?
Thawj Txoj Cai ntawm Thermodynamics: Lub zog tuaj yeem hloov pauv ntawm ib daim ntawv mus rau lwm qhov, tab sis nws tsis tuaj yeem tsim lossis rhuav tshem. … Thawj txoj cai ntawm Thermodynamics (Kev txuag) hais tias lub zog ib txwm khaws cia, nws tsis tuaj yeem tsim lossis rhuav tshem. Hauv qhov tseeb, lub zog tuaj yeem hloov los ntawm ib daim ntawv mus rau lwm qhov.
Koj puas tsim teeb meem?
vim lub zogkev txuag txoj cai, kev tsim ntawm ib khub ntawm fermions (qhov teeb meem) tawm ntawm ib qho photon tsis tuaj yeem tshwm sim. Txawm li cas los xij, teeb meem kev tsim yog tso cailos ntawm cov cai no thaum muaj lwm cov khoom (lwm tus boson, lossis txawm tias ib qho fermion) uas tuaj yeem faib cov thawj photon lub zog.
