kwv yees li 3.5 lab degrees Fahrenheit
Yog li ntawd, qhov hluav taws xob ntawm lub hnub kub npaum li cas?
5,778k
Tom qab ntawd, lo lus nug yog, qhov kub ntawm lub hnub hauv Kelvin yog dab tsi? Sab hauv tub ntxhais yog hais txog 6000 degrees Kelvin (10 000 degrees Fahrenheit) thiab qhov ntawd yog li kub raws li cov nto ntawm lub hnub ! Nyob rau hauv hnub Nws yog qhov kub ntau dua (~ 20 000 000 degrees Fahrenheit!), vim yog cov tshuaj tiv thaiv nuclear uas tso cua sov los ntawm qhov chaw ntawm hnub.
Nyob rau hauv no hais txog, pes tsawg degrees yog lub saum npoo ntawm lub hnub?
Qhov kub ntawm lub hnub yog li ntawm 10,000 Fahrenheit (5, 600 Celsius). Qhov kub nce ntawm lub hnub sab hauv mus rau qhov chaw kub heev ntawm lub hnub uas nws ncav cuag 27, 000, 000 Fahrenheit ( 15, 000, 000 Celsius).
Lub hnub hluav taws xob yog dab tsi?
Cov Lub hnub lub radiative cheeb tsam yog qhov seem ntawm lub hnub ci sab hauv nruab nrab ntawm cov tub ntxhais innermost thiab sab nrauv convective cheeb tsam . Hauv radiative cheeb tsam , lub zog tsim los ntawm nuclear fusion nyob rau hauv cov tub ntxhais txav tawm sab nraud li electromagnetic hluav taws xob . Hauv lwm lo lus, lub zog yog xa los ntawm photons.

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
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
