Gas yog ib yam khoom nrog tsis muaj meej ntim thiab tsis muaj meej puab . Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim. Gas, ntawm qhov tod tes, muaj ib lub ntim uas hloov pauv kom haum rau ntim ntawm nws lub thawv. Cov molecules nyob rau hauv ib tug roj yog sib nrug heev piv nrog cov molecules nyob rau hauv ib tug khoom los yog ib tug kua.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi tsis muaj qhov ruaj khov tab sis tsis muaj ntim ruaj khov?
Teb thiab piav qhia: Theem ntawm qhov teeb meem ntawd tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog ib gas. A gas tsis muaj qhov ruaj khov.
Ib yam li ntawd, vim li cas cov kua dej tsis muaj qhov ruaj khov? Cov kua dej , vim lawv ntws, tuaj yeem tuav txhua yam puab lawv thawv muaj , yog li lawv ua tsis muaj qhov ruaj khov . Vim cov particles hauv kua nyob sib ze heev (NW nyuam qhuav sib nrug tshaj hauv cov khib nyiab) kua ua tsis yog yooj yim compress, yog li lawv ntim yog tsau.
Hais txog qhov no, lub xeev ntawm qhov teeb meem twg tsis muaj qhov ntim ruaj khov lossis cov duab?
Roj
Vim li cas gases tsis muaj qhov ruaj khov thiab ntim?
Cov molecules hauv cov pa sib nrug heev. Yog li ntawd, cov pa tsis yog muaj qhov ntim ruaj khov tsis yog ib daim duab ruaj . Piv txwv li nyob rau hauv solids, nws muaj qhov ruaj khov thiab ib lub ntim ruaj vim molecules a cov khoom yog nyob ze thiab nruj nreem ntim ua ke. Nws yuav siv lub puab ntawm lub thawv nws muab tso rau hauv.

Vim li cas cov khoom muaj qhov ruaj khov thiab ntim?
1 Teb. Cov khoom muaj qhov ruaj khov thiab nyob hauv ib lub ntim ruaj khov. Vim hais tias cov khoom nyob rau hauv cov kua yog sib ze heev (Ntsuas ntxiv sib nrug tshaj nyob rau hauv cov khib nyiab) cov kua tsis yooj yim compress, yog li lawv ntim yog tsau. Gases kuj tuaj yeem ntws, yog li tuav cov duab ntawm lawv lub thawv tag nrho
Vim li cas roj tsis muaj qhov ruaj khov?
Cov molecules hauv cov pa roj yog sib nrug heev. Yog li ntawd, cov roj gases tsis muaj qhov ntim ruaj khov lossis cov duab ruaj khov. Piv txwv li nyob rau hauv cov khib nyiab, nws muaj qhov ruaj khov thiab lub ntim ruaj khov vim tias cov molecules hauv cov khoom yog sib ze thiab nruj nreem ntim ua ke. Nws yuav siv lub thawv uas nws muab tso rau hauv
Puas yog cov pa roj tsis muaj qhov ruaj khov thiab ntim?
Cov roj yog ib yam khoom uas tsis muaj qhov ntim thiab tsis muaj qhov tseeb. Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim. Ib qho roj, ntawm qhov tod tes, muaj qhov ntim uas hloov pauv kom haum rau qhov ntim ntawm nws lub thawv. Cov molecules nyob rau hauv ib tug roj yog sib nrug heev piv nrog rau cov molecules nyob rau hauv ib tug khoom los yog kua
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
