txheeb ze ntom ntom, lossis lub ntiajteb txawj nqus, yog qhov sib piv ntawm qhov ntom ntom (qhov loj ntawm chav tsev ntim) ntawm cov khoom rau qhov ntom ntawm cov khoom siv siv. … Ib yam khoom uas muaj qhov sib txheeb ze dua 1 yuav tog. Kub thiab siab yuav tsum tau teev rau ob qho tib si tus qauv thiab kev siv
Puas kub tseem ceeb hauv qhov ntom ntom?
Density yog lub cev khoom ntawm cov khoom uas sib piv kev sib raug zoo ntawm ntim thiab loj. Qhov ntom raug cuam tshuam los ntawm qhov kub thiab txias vim tias qhov kub nce ntxiv yog li lub zog kinetic ntawm cov khoom ua haujlwm.
Vim li cas qhov kub ntawm qhov ntsuas qhov ntsuas tau teev tseg?
chav tsev twg SI yuav tsim nyog tshaj rau kev ntsuas qhov loj ntawm lub rooj? … Vim li cas qhov kub ntawm qhov ntsuas qhov ntsuas feem ntau tau teev tseg? ntom sib txawv nrog qhov kub thiab txias vim qhov ntim sib txawv nrog qhov kub thiab qhov ceev yog sib npaug rau qhov loj / ntimCov khoom dab tsi yuav ntab hauv dej?
Qhov kub hloov pauv li cas?
Density is ncaj proportional to pressure and indirect proportional to temperature. Thaum lub siab nce, nrog rau qhov kub thiab txias, qhov ceev nce. Hloov pauv thaum kub nce, nrog lub siab tas li, qhov ceev txo.
Puas yog qhov kub thiab txias?
Kub yog qhov ntsuas kub. Qhov ntom ntom yog qhov ntsuas ntawm qhov ze npaum li cas ib qho chaw muab ntim tau lossis nws yog qhov piv ntawm qhov loj ntawm qhov chaw rau nws ntim. Qhov kev sib raug zoo ntawm qhov ceev thiab qhov kub thiab txias yog inversely proportional. Kev hloov ntawm qhov ceev yuav tshwm sim hauv qhov kev hloov pauv ntawm qhov kub thiab qhov sib txawv.
