Thaum twg dej khov los yog lwm yam khoom yaj , nws muaj peev xwm zog nce . Los ntawm thermal kinetic zog , los yog kub, ua tsis yog nce thaum melting . Lub zog muaj peev xwm yog latent zog uas tuaj yeem tso los ntawm dej, thiab qhov no nce vim dej yuav tso cua sov zog yog tias nws khov dua.

Yog li ntawd, vim li cas lub zog muaj peev xwm nce thaum lub sij hawm hloov pauv?

Cov zog uas yog hloov thaum lub sij hawm hloov yog muaj peev xwm zog . Thaum lub sijhawm hloov pauv , cua sov ntxiv (PE nce ) los yog tso tawm (PE txo) yuav tso cai rau cov molecules txav sib nrug los yog tuaj ua ke. Thaum tshav kub kub absorbed ua rau cov molecules txav mus deb sib nrug los ntawm overcoming lub intermolecular rog ntawm attraction.

Tsis tas li ntawd, yuav ua li cas rau lub zog muaj zog thaum kub nce? Yog lawm, muaj peev xwm zog nce nrog nce kub rau yam tsawg kawg yog peb yam nram qab no: Thaum siab dua kub , ntau atoms / molecules nyob rau hauv cov hluav taws xob zoo siab. Cov xeev hluav taws xob siab dua sib raug rau ntau dua muaj peev xwm zog . Muaj Peev Xwm Zog yog -2 npaug Kinetic Zog.

Ntawm no, puas muaj peev xwm nce ntxiv thaum dej khov yaj?

Thaum twg dej khov los yog lwm yam khoom yaj , nws muaj peev xwm zog nce . Tseeb tiag, qhov no yog tib qho nce hauv zog , los ntawm thermal kinetic zog , los yog kub, ua tsis yog nce thaum yaj . Ntawm txhua theem hloov dej, seb dej khov mus ua kua dej los yog kua dej mus rau dej vapor, lub muaj peev xwm zog txo.

Vim li cas lub zog muaj peev xwm nce?

Qhov system muaj peev xwm zog yog nce los ntawm kev nce qhov siab. Tom qab ntawd, lub ntiajteb txawj nqus yuav dhau mus, ua rau feem ntau ntawm cov muaj peev xwm zog hloov mus rau kinetic zog . Ib qho ntawm cov khoom seem zog uas tsis tau hloov dua siab tshiab rau hauv kinetic zog los ntawm qhov kawg ntawm kev caij yog zog poob vim kev sib txhuam.
