Zitsanzo zitatu za lamulo la Gay-Lussac (voliyumu yosasinthasintha ya isochoric)
1. Mipweya yambiri poyamba imakhala ndi mphamvu ya P ndi kutentha kwa T. Ngati mpweyawo udutsa mu njira ya isochoric kotero kuti mphamvu yake imakhala yowirikiza kanayi kuposa mphamvu yoyambirira, ndiye kuti kutentha kwa mpweyawo kumasintha kukhala...

Ndizodziwika kuti :
Kupanikizika koyamba (P)1) = P
Kupanikizika komaliza (P)2) = 4P
Kutentha koyambirira (T)1) = T
Anafunsa kutentha komaliza (T)2)
Yankhani :
Hukum Gay-Lussac (njira ya isochoric kapena voliyumu yosalekeza) :
Kutentha kwa mpweya kumasintha kufika pa nthawi zinayi kuposa kutentha koyamba.
2. Gasi ali mu chotengera chotsekedwa kutentha koyambirira kwa 27°C. Kuti mpweya uwonjezere kupanikizika, kutentha kwa chipinda ndi...
Zokambirana
Ndizodziwika kuti :
Kupanikizika koyamba (P)1) = P
Kupanikizika komaliza (P)2) = 2P
Kutentha koyambirira (T)1= = 27oC + 273 = 300 K
Anafunsa kutentha komaliza (T)2)
Yankhani :
Kutentha kwa chipinda ndi madigiri 327oC.
3. Matayala a njinga yamoto ali ndi mphamvu yoyezera ya 2 atm pa kutentha kwa 27oC. Njinga yamoto ikakwera, kutentha mkati mwa tayala kumasintha kufika pa madigiri 47oC. Ngati kukulitsa sikunyalanyazidwa ndiye kuti kuthamanga kwa mpweya mu tayala kumasintha kukhala...

Sinthani kupanikizika koyezera kukhala kupanikizika kotheratu. Kupanikizika kotheratu = kupanikizika koyezera + kupsinjika kwa mlengalenga
Ndizodziwika kuti :
Kupanikizika kwa mpweya = 1 atm = 1 x 105 Pascal
Kupanikizika koyamba koyezera = 2 atm = 2 x 105 Pascal
Kupanikizika koyambirira (P)1) = 1 atm + 2 atm = 3 atm = 3 x 105 Pascal
Kutentha koyambirira (T)1= = 27oC + 273 = 300 K
Kutentha komaliza (T)1= = 47oC + 273 = 320 K
Anafunsa : Kupanikizika komaliza
Yankhani :
Kupanikizika komaliza = kupanikizika komaliza - kupsinjika kwa mlengalenga
Kupanikizika komaliza kwa gauge = 3,2 atm - 1 atm
Kupanikizika komaliza kwa gauge = 2,2 atm
