Mechanical quab yuam uas thawb a foob pob ua ntxaij oraircraft los ntawm huab cua yog hu ua thrust. Hauv no kev sim , koj yuav ua ib balloon foob pob ua ntxaij uas yog propelled los ntawm siab. Lub escaping air exerts ib lub zog ntawm lub balloon nws tus kheej. Cov balloon thawb rov qab rau hauv ib qho kev piav qhia los ntawm Newton's Third Law of Motion.
Tsis tas li lo lus nug yog, dab tsi yog tag nrho cov quab yuam ua rau lub foob pob hluav taws balloon?
Muaj ob lub ntsiab zog acting ntawm balloon foob pob ua ntxaij tsheb: Kev sib txhuam thiab cua tsis kam. Kev sib txhuam zog yog qhov tsis kam ntawm ob yam khoom swb tawm tsam ib leeg.
Ib yam li ntawd, lub foob pob hluav taws ua haujlwm li cas? A balloon muab piv txwv yooj yim li cas a foob pob ua ntxaij cav ua haujlwm . Cov cua daig hauv lub balloon thawb tawm qhov qhib kawg, ua rau lub balloon mus tom ntej. Lub zog ntawm kev khiav tawm ntawm huab cua yog "kev nqis tes ua"; kev txav ntawm lub balloon pem hauv ntej yog qhov "reaction" kwv yees los ntawm Newton's Third Law of Motion.
Ntxiv mus, yuav ua li cas cua tawm ntawm lub zais pa?
Cov me me, tus kheej helium molecules tuaj yeem khiav tawm ntawm qhov me me hauv cov latex yooj yim dua li cov pa oxygen los yog nitrogen molecules tuaj yeem ua tau. Thaum kawg lawv yuav tag nrho tawm , tab sis lub helium muaj lub sij hawm yooj yim dua escaping. Qhov no yog vim li cas koj helium balloons deflate sai dua cov uas koj sau nrog huab cua.
Dab tsi ua rau foob pob hluav taws mus?
Feem ntau foob pob ua ntxaij cav tig cov roj rau hauv cov roj kub. Lub cav thawb cov roj tawm nws rov qab. Cov roj ua tus foob pob ua ntxaij txav mus tom ntej. A foob pob ua ntxaij cav ua haujlwm hauv qhov chaw, qhov twg tsis muaj cua.

Lub hom phiaj ntawm kev kho cua sov yog dab tsi tshwm sim thaum siv hluav taws xob ntau dhau?
Kev kho cua sov tua cov kab mob thiab ua rau lawv lo rau hauv iav kom lawv tsis tuaj yeem yaug tawm. Inheat-kho yuav ua li cas yog tias siv ntau dhau lawm? Nws yuav ua rau lub cev puas tsuaj
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer. Cov tshuaj tua hluav taws qhuav qhuav kuj tseem yuav siv tsis tau rau feem ntau
