Muaj pes tsawg lub balloons tau ib lub tog raj kheej ntawmheliumsau?
Piv txwv li, ib lub tog raj kheej ntawm 40Lheliumgas nrog lub siab ntawm 10MPa
Lub balloon yog hais txog 10L, lub siab yog 1 cua thiab lub siab yog 0.1Mpa
40 * 10 / (10 * 0.1) = 400 balloons
Qhov ntim ntawm lub zais pa nrog txoj kab uas hla ntawm 2.5 meters = 3.14 * (2.5 / 2) 2 = 4.90625 square metres = 4906.25 litres
Raws li cov qauv txheej txheem, 1mol ntawm cov pa roj yog 22.4 litres, yog li tag nrho ntawm 4906.25 / 22.4 = 219mol yog xav tau, yog li hais txog 219mol ntawmheliumyog xav tau, yog li 219mol * 4g / mol = 876g ntawmheliumyog xav tau
Yuav ntev npaum li cas aheliumballoon kawg?
Ntev npaum li cas aheliumBalloon tuaj yeem khaws cia yog ze rau qhov kub thiab txias.
Ntawm no yog ib qho piv txwv ntawm 10-ntiheliumballoon. Feem ntau, 10-ntiheliumballoon kav li 5 teev. Tau kawg, lub sijhawm tuav tsis paub meej. Yog tiasheliumBalloon khaws cia rau hauv qhov chaw sov, lub sijhawm tuav ntev dua, xws li chav cua txias, nyob rau hauv ib puag ncig zoo li no, feem ntau tuaj yeem khaws cia rau 7 teev. Qhov no nyob ntawm qhov kub thiab txias.
Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev siv sab nraum zoov: thov zam lub hnub ci ntau li ntau tau ua ntej pib ua haujlwm. Lub zais pa yuav tsis ci tom qab hnub ci, uas yog, "oxidation" cuam tshuam los ntawm qhov kub thiab txias, thiab lub neej ntevheliumballoon txo qis heev.
Yog tias koj tsis tuaj yeem zam lub hnub ncaj qha nrogheliumballoons, koj yuav tsum tau them tshwj xeeb mloog mus rau lubheliumballoons nyob rau hauv tshav ntuj. Feem ntau hais lus, lawv tuaj yeem kav ntev li 4 teev. Yog hais tias nws yog lub caij ntuj sov, lub teeb kuj muaj zog, thiab nws yog ib qho nyuaj rau khaws cia rau 4 teev. Yog li ntawd, koj yuav tsum tau them nyiaj rau lub sijhawm siv nyiaj thaum ua haujlwm.
