Suab tau taug kev ntawm kwv yees li 6000 metresper thib ob hauv qee qhov cov khoom khib nyiab thiab ntawm ib feem peb ntawm qhov ceev no hauv dej. Qhov no yog vim lub molecules ntawm cov khoom khib nyiab tau ntim ntau dua ua ke dua li hauv cov kua thiab cov hauv cov kua yog ntim nruj dua li hauv cov pa roj.

Tsuas yog li ntawd, qhov ceev ntawm lub suab los ntawm cov khib nyiab yog dab tsi?

Cov ceev suab yog qhov nrug ntawd suab nthwv dej taug kev hauv ib lub sijhawm. Cov ceev suab Hauv huab cua qhuav ntawm 20 ° C yog 343 meters ib ob. Feem ntau, suab nthwv dej taug kev sai tshaj plaws dhau ntawm cov khoom , ua raws li cov kua, thiab tom qab ntawd los ntawm cov pa roj.

Ib sab saum toj no, lub suab nrawm npaum li cas los ntawm cov kua? Thaum khov (0ºC), suab taug kev huab cua ntawm 331 meters ib ob (kwv yees 740 mph). Tab sis, ntawm 20ºC, chav tsev kub, suab taug kev ntawm 343 meters persecond (767 mph). Cov kua dej : Suab mus nrawm dua inliquids tshaj hauv gases vim molecules yog nruj dua.

Tsis tas li ntawd, yuav ua li cas suab nthwv dej sai dua hauv cov khib nyiab?

Vim lawv yog ze ze, dua ua tau collide sai heev, piv txwv li nws yuav siv sij hawm tsawg dua rau lub molecule ntawm lub ruaj rau 'pob' rau hauv nws cov neeg zej zog. Cov khoom yog ntim ua ke nruj dua li cov kua thiab roj, li no soundtravels ceev tshaj plaws hauv cov khoom . Qhov deb ntawm cov kua yog luv dua nyob rau hauv gases, tab sis ntev tshaj nyob rau hauv cov khoom khib nyiab.

Dab tsi yog suab mus nrawm tshaj plaws?

Qhov ceev ntawm suab nyob ntawm qhov nruab nrab uas nws thauj. Suab mus nrawm tshaj plaws khoom, qeeb dhau dej thiab qeeb tshaj ntawm cov pa.
