Qhov sib txawv tseem ceeb ntawm latent cua sov ntawm fusion thiab vaporization yog tias latent cua sov ntawm fusion yog cov cua sov uas cov khoom siv yuav tsum tau hloov nws theem ntawm cov khoom theem mus rau cov kua theem ntawm qhov kub thiab txias qhov chaw latent cua sov ntawm vaporization. yog cov cua kub uas cov khoom ua kua yuav tsum hloov nws theem ntawm cov kua theem mus rau theem vapor ntawm qhov kub thiab txias.

Latent cua sov ntawm fusion thiab vaporization yog hais txog kev hloov pauv ntawm lub zog cua sov ntawm qhov kub thiab txias. Lub latent cua sov ntawm fusion piav qhia txog kev hloov pauv ntawm cov cua sov ntawm cov khoom siv melting point. Ntawm qhov tsis sib xws, latent cua sov ntawm vaporization piav qhia txog kev hloov pauv hauv tshav kub ntawm qhov kub ntawm cov khoom. Ib yam li ntawd, muaj qee qhov sib txawv ntawm ob lub tswv yim tshuaj.

Dab tsi yog Latent Kub ntawm Fusion?

Latent cua sov ntawm fusion yog cov cua sov uas cov khoom siv yuav tsum hloov nws theem ntawm cov theem khoom mus rau theem ua kua ntawm qhov kub thiab txias, txhais los ntawm H_f Hauv lwm lo lus, ib chav tsev loj ntawm ib yam khoom yuav tsum muaj lub zog cua sov uas sib npaug rau cov cua sov latent ntawm fusion (ntawm cov khoom tshwj xeeb) ntawm nws qhov melting point, thiaj li hloov mus rau hauv nws cov kua theem. Fusion yog melting (liquefying ib qho khoom los ntawm kev muab cua sov). Cov khoom sib txawv muaj cov ntsiab lus sib txawv; Yog li, qhov sib txawv rau H_f

Sib npaug ntawm Latent Kub ntawm Fusion

Qhov sib npaug rau H_{f yog raws li nram no:}

H_f=ΔQ_{f/ m}

Ntawm no, ΔQ_{fyog qhov hloov pauv ntawm lub zog ntawm cov khoom thiab m yog qhov loj ntawm cov khoom.}

Latent Kub ntawm Vaporization yog dab tsi?

Latent cua sov ntawm vaporization yog cov cua kub uas cov khoom ua kua yuav tsum tau hloov nws theem ntawm cov kua theem mus rau theem vapor ntawm qhov kub thiab txias, denoted los ntawm H_{v Hauv Lwm cov lus, ib chav tsev loj ntawm cov khoom yuav tsum muaj lub zog cua sov uas sib npaug rau cov cua sov latent ntawm vaporization (ntawm cov khoom tshwj xeeb) ntawm nws qhov kub kub, txhawm rau hloov mus rau hauv nws theem roj.}

Kev sib npaug ntawm Latent Kub ntawm Vaporization

Qhov sib npaug rau H_{v yog raws li nram no:}

H_v=ΔQ_{v/ m}

Ntawm no ΔQ_{v yog qhov hloov pauv ntawm lub zog ntawm cov khoom thiab m yog qhov loj ntawm cov khoom.}

Dab tsi yog qhov txawv ntawm qhov kub thiab txias ntawm fusion thiab vaporization?

Latent heat of fusion yog tus nqi ntawm cov cua sov uas cov khoom siv yuav tsum tau hloov nws cov theem los ntawm cov theem khoom mus rau theem ua kua ntawm qhov kub thiab txias tas li thaum Latent cua sov ntawm vaporization yog cov cua kub uas cov khoom ua kua yuav tsum hloov. nws theem ntawm cov kua theem mus rau theem vapor ntawm qhov kub thiab txias.

Latent heat of fusion is denoted by H_f while latent heat of vaporization is denoted by H_{yHais txog qhov kub thiab txias., latent cua sov ntawm fusion yog rau kev hloov ntawm tshav kub ntawm lub melting point ntawm ib yam khoom whereas lub latent cua sov ntawm vaporization yog hais txog qhov kev hloov ntawm tshav kub ntawm boiling point ntawm ib yam khoom.}

Summary – Latent Kub ntawm Fusion vs Vaporization

Cov cua sov tsis txaus yog hais txog qhov hloov pauv ntawm cov cua sov ntawm qhov kub thiab txias. Cov khoom sib txawv muaj qhov sib txawv latent heats ntawm lawv cov ntsiab lus melting thiab boiling point. Qhov sib txawv ntawm latent cua sov ntawm fusion thiab vaporization yog tias ib yam khoom hloov nws theem ntawm cov khoom mus rau cov kua thaum peb muab ib tug npaum li cas ntawm cov cua sov uas yog sib npaug zos rau latent tshav kub ntawm fusion whereas ib yam khoom hloov nws theem ntawm kua rau vapor thaum peb muab ib tug cov cua sov uas sib npaug rau latent cua sov ntawm vaporization.
