Cov ntaub ntawv yooj yim ntawm kev tawg thiab sib tov raug suav hais tias yog lub cev kev hloov , mas sib tov tus cov khoom xyaw ntawm lub ncuav mog qab zib tsis yog ib qho yooj yim sib tov txheej txheem. A tshuaj hloov pib tshwm sim thaum lub cov khoom xyaw yog tov, tsim cov tshuaj tshiab.
Yog li ntawd, kev sib xyaw hmoov nplej thiab qe yog kev hloov tshuaj?
Thaum cov ntaub ntawv yog rhuab lawv undergo a tshuaj hloov . Cov tshuaj tiv thaiv yog tsis thim rov qab. Qab zib, hmoov thiab qe sib cais tsis tau lawm. Cov khoom ntawm cov ntaub ntawv hloov pauv yog li nws yog a tshuaj hloov.
Tsis tas li ntawd, kev sib xyaw butter thiab qab zib yog kev hloov tshuaj? Tshwj xeeb, muaj xya tshuaj tiv thaiv uas qab zib yog siv rau thaum lub sij hawm ci txheej txheem. Qab Zib thiab butter tuaj yeem ua ke nrog ib rab diav ntoo lossis tov khoom ua ncuav qab zib thiab ncuav qab zib teeb thiab fluffy. Kua nplaum rog yog ntom, thiab sib tov nws nrog qab zib muab aeration. Qab Zib yog hygroscopic.
Tsuas yog li ntawd, puas yog kev hloov tshuaj lom neeg?
Raws li koj ci ncuav mog qab zib, koj tab tom tsim ib qho endothermic tshuaj cov tshuaj tiv thaiv ntawd kev hloov ooey-gooey batter rau hauv fluffy, qab kho! Thaum tshav kub kub pab ci hmoov tsim cov npuas me me ntawm cov pa roj, uas ua rau lub ncuav mog qab zib ci thiab fluffy. Thaum tshav kub kub ua rau cov protein los ntawm lub qe mus rau hloov thiab ua kom lub ncuav mog qab zib khov.
Puas yog glow sticks hloov tshuaj los yog lub cev?
Glow sticks tsim teeb los ntawm a tshuaj tiv thaiv . Glow sticks muaj peb yam tshuaj sib txawv. Cov electrons tam sim ntawd poob rov qab, tso lub zog ntxiv raws li pom lub teeb. Cov tshuaj tiv thaiv ua qhov chaw hauv ib glow stick tsim lub teeb es tsis txhob kub, tab sis nws yog cuam tshuam los ntawm tshav kub.
