1. Hauv ib lub thawv kaw, cov pa roj nthuav dav kom qhov ntim kawg dhau los ua 3 npaug ntawm qhov ntim pib (V = ntim pib, T = qhov kub pib ). Qhov kub kawg yog dab tsi?
Paub:
Qhov ntim pib (V 1 ) = V
Qhov ntim kawg (V 2 ) = 3V
Kub pib (T 1 ) = T
Xav tau: Qhov kub kawg (T 2 )
Tshuaj:
Cov qauv ntawm Charles txoj cai lij choj :
Qhov kub kawg ntawm cov pa roj dhau los ua 3 npaug ntawm qhov kub pib.

2. Kuv cov pa roj ua haujlwm thaum xub thawj muaj ntim V thiab kub T. Yog tias cov pa roj ua raws li cov txheej txheem isobaric kom qhov kub thiab txias dhau los ua 2 npaug ntawm qhov kub pib ces qhov ntim kawg ntawm cov pa roj yog ...
Paub:
Qhov ntim pib (V 1 ) = V
Kub pib (T 1 ) = T
Qhov kub kawg (T2 ) = 2T
Xav tau: phau kawg (V 2 )
Tshuaj:
Qhov ntim kawg ntawm cov pa roj dhau los ua 2 npaug ntawm qhov ntim pib.

3. Hauv ib lub thawv kaw, cov pa roj zoo tagnrho thaum xub thawj muaj qhov ntim ntawm 2 liv thiab qhov kub ntawm 27 o C. Yog tias qhov ntim kawg ntawm cov pa roj dhau los ua 3 liv ces qhov kub kawg yog ...
Paub:
Qhov ntim pib (V 1 ) = 2 liv = 2 dm 3 = 2 x 10 -3 m 3
Qhov ntim kawg (V 2 ) = 3 liv = 3 dm 3 = 3 x 10 -3 m 3
Kub pib (T1 ) = 27 o C + 273 = 300 K
Xav tau: Qhov kub kawg (T 2 )
Tshuaj:
Qhov kub kawg yog 177 o C lossis 177 + 273 = 450 Kelvin.
