Vim li cas dej molecules lo ua ke?

Vim li cas cov nthwv dej transverse tsim los ntawm av qeeg hu ua cov nthwv dej thib ob?

Secondary waves (S-waves) yog shear waves uas yog transverse nyob rau hauv cov xwm. Tom qab muaj xwm txheej av qeeg, S-nthwv dej tuaj txog ntawm cov chaw nres tsheb seismograph tom qab nrawm dua-tsav P-nthwv dej thiab hloov chaw hauv av perpendicular mus rau kev taw qhia ntawm kev nthuav tawm

Yuav ua li cas hydrogen bonding ntawm cov dej molecules pab piav qhia dej lub peev xwm nqus tau ntau lub zog ua ntej evaporation?

Cov hydrogen bonds hauv dej tso cai rau nws nqus thiab tso tawm lub zog cua sov qeeb dua li ntau lwm yam khoom. Qhov kub thiab txias yog ib qho kev ntsuas ntawm qhov kev txav (kinetic zog) ntawm cov molecules. Raws li cov lus tsa suab nce, lub zog yog siab dua thiab yog li kub siab dua

Puas yog dej molecules nyiam rau lwm cov polar molecules?

Raws li qhov tshwm sim ntawm dej polarity, txhua tus dej molecule attracts lwm cov dej molecules vim yog cov nqi sib txawv ntawm lawv, tsim hydrogen bonds. Dej kuj nyiam, lossis nyiam, lwm cov polar molecules thiab ions, suav nrog ntau cov biomolecules, xws li qab zib, nucleic acids, thiab qee cov amino acids

Yog vim li cas dej molecules attracted rau ib leeg?

Ntau precisely, qhov zoo thiab tsis zoo nqi ntawm hydrogen thiab oxygen atoms uas ua li dej molecules ua rau lawv attracted rau ib leeg. Cov sib nqus sib nqus sib nqus sib nqus nyiam ib leeg zoo ib yam li qhov zoo ntawm cov atoms nyiam qhov tsis zoo them atoms hauv dej molecules

Lub ntuj puas xiav vim dej hiav txwv los yog dej hiav txwv xiav vim lub ntuj?

'Lub hiav txwv zoo li xiav vim liab, txiv kab ntxwv thiab daj (ntev wavelength teeb) yog absorbed ntau zog los ntawm dej tshaj yog xiav (luv wavelength light). Yog li thaum lub teeb dawb ntawm lub hnub nkag mus rau hauv dej hiav txwv, nws feem ntau yog xiav uas tau rov qab los. Ib yam li ntawd, lub ntuj xiav.'
