Rewrite qhov sib npaug li n Rt =PV n R t = PV. Faib txhua lub sij hawm los ntawm n R thiab ua kom yooj yim. Faib txhua lub sij hawm hauv n Rt =PV n R t = P V by n R n R.
Ib sab ntawm qhov no, koj yuav ua li cas xam cov roj av zoo?
Ideal Gas Law Formula
- Ideal Gas Law Formula Cov lus nug:
- Teb: Qhov Volume yog V = 890.0mL thiab qhov kub yog T = 21 ° C thiab qhov siab yog P = 750mmHg.
- PV = nRT.
- Teb: Tus naj npawb ntawm moles yog n = 3.00moles, kub yog T = 24 ° C thiab siab yog P = 762.4 mmHg.
- PV = nRT.
Tom qab, lo lus nug yog, tus nqi ntawm R yog dab tsi? Cov tus nqi ntawm cov pa tsis tu ncua ' R ' nyob ntawm cov units siv rau siab, ntim thiab kub. R = 0.0821 litre·atm/mol·K. R = 8.3145 J/mol·K. R Luas = 8.2057 m3· atm/mol · K. R = 62.3637 L·Torr/mol·K or L·mmHg/mol·K.
Tom qab ntawd, ib tus tuaj yeem nug, ATM suav li cas?
1 atm kev = 760 torr = 760 mmHg. n = tus naj npawb ntawm moles, ntsuas hauv moles (recall 1 mole = 6.022x1023 molecules), abbreviated mol. T = kub, feem ntau ntsuas nyob rau hauv degrees Kelvin, abbreviated K. 273 K = 0oC, thiab qhov loj ntawm 1 degree K yog tib yam li qhov loj ntawm 1 degree C.
Ua li cas koj thiaj nrhiav tau lub siab?
Siab thiab quab yuam muaj feem cuam tshuam, thiab yog li koj tuaj yeem ua tau xam ib qho yog tias koj paub lwm tus los ntawm kev siv physics equation, P = F / A. Vim siab yog quab yuam muab faib los ntawm cheeb tsam, nws meter-kilogram-thib ob (MKS) units yog newtons ib square meter, los yog N / m2.

VIDEO Ib yam li ntawd, 4 kauj ruam los daws qhov sib npaug yog dab tsi? A 4-Step Guide to Solving Equations (Part 2) Kauj Ruam 1: Simplify txhua sab ntawm qhov sib npaug. Raws li peb tau kawm dhau los, thawj kauj ruam ntawm kev daws qhov sib npaug yog ua kom qhov sib npaug yooj yim li sai tau.
Koj yuav daws li cas rau centripetal acceleration?
Lub centripetal ('center-seeking') acceleration yog qhov kev txav mus rau sab hauv ntawm qhov chaw ntawm lub voj voog. Lub acceleration yog sib npaug rau lub square ntawm qhov tshaj tawm, muab faib los ntawm lub vojvoog ntawm txoj kev ncig
Yuav ua li cas koj nrhiav tau qhov kev daws teeb meem rau ib khub xaj?
Txhawm rau txheeb xyuas yog tias tus khub txiav txim yog qhov kev daws teeb meem rau qhov sib npaug, koj tuaj yeem ua qhov kev sim. Txheeb xyuas qhov x-tus nqi hauv tus khub xaj thiab ntsaws rau hauv qhov sib npaug. Thaum koj ua kom yooj yim, yog tias tus y-tus nqi koj tau txais yog tib yam li y-tus nqi hauv tus khub xaj, ces tus khub txiav txim yog qhov kev daws teeb meem rau qhov sib npaug
Yuav ua li cas koj daws rau ib tug tsis paub exponent?
Exponential equations uas tsis paub tshwm sim ib zaug Qhov tshwm sim yog tias tus exponential sawv ib leeg ntawm ib sab ntawm kab zauv, uas tam sim no muaj daim ntawv b f = a, qhov twg tus exponent f muaj cov tsis paub x. Yog hais tias lub hauv paus ntawm tus exponential yog e ces coj natural logarithms ntawm ob sab ntawm kab zauv
Koj yuav daws li cas rau ob daim duab peb sab?
Kev daws SSA Daim duab peb sab siv Txoj Cai ntawm Sines ua ntej los xam ib qho ntawm ob lub ces kaum; tom qab ntawd siv peb lub kaum sab xis ntxiv rau 180 ° kom pom lwm lub kaum sab xis; Thaum kawg siv Txoj Cai ntawm Sines dua kom pom qhov tsis paub
