Zitsanzo zitatu za lamulo la Boyle (kutentha kosasinthasintha kwa kutentha)
1. Mpweya wabwino kwambiri poyamba umakhala ndi mphamvu ya P ndi voliyumu ya V. Ngati mpweyawo udutsa mu njira ya isothermal kotero kuti mphamvuyo imakhala yowirikiza kanayi kuposa mphamvu yoyambirira, mphamvu ya mpweyayo imasintha kukhala...

Ndizodziwika kuti :
Kupanikizika koyamba (P)1) = P
Kupanikizika komaliza (P)2) = 4P
Voliyumu yoyamba (V)1) = V
Anafunsa : voliyumu yomaliza ya mpweya (V2)
Yankhani :
Lamulo la Boyle (njira yosinthira kutentha kapena kutentha kosalekeza) :
PV = yosasintha
P1 V1 =P2 V2
(P)(V) = (4P)(V)2)
V = 4 V2
V2 = V / 4 = ¼ V
Kuchuluka kwa mpweya kumasintha kufika pa ¼ ya kuchuluka koyambirira.
2. Mu chidebe chotsekedwa, mpweya umakula kotero kuti voliyumu yake imasintha kufika pa voliyumu yoyamba kawiri (V = voliyumu yoyamba, P = kupanikizika koyamba). Kupanikizika kwa mpweya kumasintha kufika pa…

Ndizodziwika kuti :
Kupanikizika koyamba (P)1) = P
Voliyumu yoyamba (V)1) = V
Voliyumu yomaliza (V)2) = 2V
Anafunsa : kupanikizika komaliza (P2)
Yankhani :
P1 V1 =P2 V2
PV = P2 (2V)
P=P2 (2)
P2 = P / 2 = ½ P
Kuthamanga kwa mpweya kumasintha kufika pa ½ kukakamiza koyamba.
3. Mu chotengera chotsekedwa muli mpweya womwe uli ndi mphamvu ya 2 atm ndi voliyumu ya lita imodzi. Ngati mphamvu ya mpweya ifika pa 4 atm ndiye kuti mphamvu ya mpweya idzakhala...
Zokambirana
Ndizodziwika kuti :
Kupanikizika koyamba (P)1) = 2 atm = 2 x 105 Pascal
Kupanikizika komaliza (P)2) = 4 atm = 4 x 105 Pascal
Voliyumu yoyamba (V)1) = malita 1 = 1 dm3 = 1x10 pa-3 m3
Anafunsa : Voliyumu yomaliza (V)2)
Yankhani :
P1 V1 =P2 V2
(2x105)(1 x 10-3) = (4 x 105) V2
(1)(1 x 10-3) = (2) V2
1 × 10-3 = (2) V2
V2 = ½ x 10-3
V2 = 0,5x10 pa-3 m3 = 0,5 dm3 = 0,5 lita
