Nyob rau hauv no hais txog, dab tsi yog 6 lub zog ntawm cov khib nyiab?
Cov duab meej, meej ntim , meej melting point, siab ceev, incompressibility, thiab tsawg diffusion.
5 yam khoom ua kua yog dab tsi? Tag nrho cov kua dej qhia cov yam ntxwv hauv qab no:
- Cov kua yuav luag incompressible. Hauv cov kua dej molecules zoo nkauj nyob ze rau ib leeg.
- Cov kua muaj qhov ntim ruaj khov tab sis tsis muaj qhov ruaj khov.
- Cov kua dej ntws los ntawm siab mus rau theem qis.
- Cov kua dej muaj lawv cov ntsiab lus kub kub saum chav tsev kub, nyob rau hauv ib txwm muaj.
Xav txog qhov no, cov khoom ntawm cov khoom yog dab tsi?
Cov khoom ntawm Solids. Khoom yog cov yam ntxwv ntawm cov qauv rigidity thiab tsis kam mus rau kev hloov ntawm cov duab los yog ntim. Tsis zoo li kua, a khov kho yam khoom tsis ntws mus rau hauv cov duab ntawm nws lub thawv, thiab tsis nthuav mus sau tag nrho cov ntim uas muaj rau nws zoo li roj.
Dab tsi yog 3 yam khoom ntawm cov khoom?
(i) Cov khoom muaj cov duab meej thiab cov ciam teb sib txawv. (ii) Cov khoom muaj qhov ntim ruaj khov. (iii) Lawv muaj qhov tsis txaus ntseeg. (iv) Lawv nruj (lawv cov duab tsis tuaj yeem hloov tau).
