Lub entropy ntawm lub system, uas yog δQ / T, nce los ntawm δQ / 273K. Lub tshav kub δQ rau cov txheej txheem no yog lub zog yuav tsum tau hloov dej los ntawm cov khoom hauv lub xeev mus rau lub xeev ua kua, thiab hu ua enthalpy ntawm fusion, piv txwv li ΔH rau ice fusion.
Puas fusion nce entropy?
Entropy ib txwm nce. Fusion yog cov txheej txheem tsis thim rov qab thiab nce entropy los ntawm me ntsis.
Dab tsi yog qhov hloov pauv entropy hauv fusion?
4.6 Thermodynamic Kev Kho Mob ntawm Cov Kub Kub
qhov twg T m yog qhov kub ntawm qhov melting, ΔHm yog cov enthalpy ntawm fusion, thiab ΔSm yog qhov entropy ntawm fusion. Kev hloov pauv ntawm entropy ntawm melting yog ib qho kev ntsuas ntawm qhov kev hloov pauv ntawm qhov kev txiav txim hauv cov qauv thaum melting tshwm sim, yog li nyob ntawm cov qauv tshuaj.
Puas yog entropy ntawm fusion zoo lossis tsis zoo?
Lub entropy ntawm fusion yog qhov nce hauv entropy thaum melting ib yam khoom. Qhov no yog yuav luag ib txwm zoo txij li qib ntawm kev tsis sib haum xeeb nce hauv kev hloov pauv ntawm cov khoom siv crystalline mus rau cov qauv tsis sib xws ntawm cov kua; Tsuas paub qhov kev zam yog helium.
Thaum lub entropy ntawm qhov system txo qis?
Entropy yog qhov poob ntawm lub zog muaj los ua haujlwm. Lwm daim ntawv ntawm txoj cai thib ob ntawm thermodynamics hais tias tag nrho cov entropy ntawm lub kaw lus yuav nce los yog nyob twj ywm; nws yeej tsis txo qis.
