1. Mpweya wina wabwino poyamba umakhala ndi mphamvu ya P ndi voliyumu V. Ngati mpweyawo udutsa mu njira ya isothermal kotero kuti mphamvu yomaliza imakhala yowirikiza kanayi kuposa mphamvu yoyambirira, ndiye kuti mphamvu yomaliza ya mpweya ndi…
Zodziwika:
Kupanikizika koyambirira (P 1 ) = P
Kupanikizika komaliza (P2 ) = 4P
Voliyumu yoyambirira (V 1 ) = V
Kufunidwa: Voliyumu Yomaliza (V 2 )
Yankho:
Fomula ya lamulo la Boyle :
PV = yosasintha
P 1 V 1 = P 2 V 2
(P)(V) = (4P)(V 2 )
V = 4 V 2
V 2 = V / 4 = ¼ V
Kuchuluka komaliza kwa mpweya ndi ¼ kuchulukitsa kuchuluka koyambirira.

2. Mu chidebe chotsekedwa, mpweya umakula kotero kuti voliyumu yomaliza imakhala kawiri kuposa voliyumu yoyambirira (V = voliyumu yoyambirira, P = kupanikizika koyambirira). Kupanikizika komaliza kwa mpweya ndi…
Zodziwika:
Kupanikizika koyambirira (P 1 ) = P
Voliyumu yoyambirira (V 1 ) = V
Voliyumu yomaliza (V 2 ) = 2V
Kufunidwa : Kupanikizika komaliza (P 2 )
Yankho:
P 1 V 1 = P 2 V 2
PV = P 2 (2V)
P = P 2 (2)
P 2 = P / 2 = ½ P
Kuthamanga kwa mpweya kumakhala ndi theka la kukakamiza koyamba.

3. Mu chidebe chotsekedwa, mpweya wokhala ndi mphamvu ya 2 atm ndi voliyumu ya lita imodzi. Ngati mphamvu ya mpweya ifika pa 4 atm ndiye kuti mphamvu ya mpweya imakhala...
Zodziwika:
Kupanikizika koyambirira (P 1 ) = 2 atm = 2 x 10 5 Pa
Kupanikizika komaliza (P 2 ) = 4 atm = 4 x 10 5 Pa
Voliyumu yoyambirira (V 1 ) = lita imodzi = 1 dm 3 = 1 x 10 -3 m 3
Kufunidwa : Voliyumu yomaliza (V 2 )
Yankho:
P 1 V 1 = P 2 V 2
( 2 x 10 5 )(1 x 10 -3 ) = (4 x 10 5 ) V 2
( 1)(1 x 10 -3 ) = (2) V 2
1 x 10 -3 = (2) V 2
V 2 = ½ x 10 -3
V 2 = 0.5 x 10 -3 m 3 = 0.5 dm 3 = 0.5 lita s
