Piv txwv ntawm Charles txoj cai (isobaric / tas li siab)

3 Piv txwv ntawm Charles txoj cai (isobaric/constant pressure)

1. Hauv ib lub thawv kaw, cov pa roj nthuav dav kom nws qhov ntim hloov mus rau 3 npaug ntawm nws qhov ntim pib (V = ntim pib, T = kub pib). Qhov kub ntawm cov pa roj hloov mus rau…

Nws yog paub :
Qhov ntim pib (V₁) = V
Qhov ntim kawg (V₂) = 3V
Kub pib (T₁) = T
Nug : qhov kub kawg (T₂)
Jawb :
Txoj Cai Charles (isobaric lossis cov txheej txheem siab tas li) :
Qhov kub ntawm cov roj hloov mus rau 3 npaug ntawm qhov kub qub.

2. Muaj ntau cov pa roj zoo tagnrho thaum xub thawj muaj qhov ntim V thiab qhov kub T. Yog tias cov pa roj dhau los ntawm cov txheej txheem isobaric kom nws qhov kub dhau los ua ob npaug ntawm qhov kub qub ces qhov ntim ntawm cov pa roj hloov mus rau...

Nws yog paub :
Qhov ntim pib (V₁) = V
Kub pib (T₁) = T
Qhov kub kawg (T₂) = 2T
Nug : ntim kawg (V₂)
Jawb :
Qhov ntim ntawm cov roj hloov pauv mus txog 2 npaug ntawm qhov ntim thawj.

3. Hauv ib lub thawv kaw lawm muaj ib lub roj uas muaj qhov ntim ntawm 2 liv thiab qhov kub ntawm 27^oC. Yog tias qhov ntim ntawm cov roj dhau los ua 3 liv, qhov kub ntawm cov roj dhau los ua ...
Kev Sib Tham
Nws yog paub :
Qhov ntim pib (V₁) = 2 liv = 2 dm³ Luas = 2 x 10^-3 m³
Qhov ntim kawg (V₂) = 3 liv = 3 dm³ Luas = 3 x 10^-3 m³
Kub pib (T₁= 27 TZS^oC + 273 = 300 K
Nug : qhov kub kawg (T₂)
Jawb :
Qhov kub ntawm cov roj hloov mus rau 450 Kelvin lossis 177^oC.
