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

  1. Ideal Gas Law Formula Cov lus nug:
  2. Teb: Qhov Volume yog V = 890.0mL thiab qhov kub yog T = 21 ° C thiab qhov siab yog P = 750mmHg.
  3. PV = nRT.
  4. Teb: Tus naj npawb ntawm moles yog n = 3.00moles, kub yog T = 24 ° C thiab siab yog P = 762.4 mmHg.
  5. 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.
