Puisano
Hoa tsebahala :
Khatello ea pele (P)1) = P
Khatello ea ho qetela (P)2) = 4P
Mocheso oa pele (T)1) = T
E botsitsoe : mocheso oa ho qetela (T2)
Jawab :
Hukum Gay-Lussac (ts'ebetso ea isochoric kapa ea molumo o sa fetoheng) :
Mocheso oa khase o fetoha ka makhetlo a mane ho feta mocheso oa pele.
2. Khase e ka har'a sejana se koetsoeng mochesong oa pele oa 27°C. Ho eketsa khatello habeli, mocheso oa kamore ke...
Puisano
Hoa tsebahala :
Khatello ea pele (P)1) = P
Khatello ea ho qetela (P)2) = 2P
Mocheso oa pele (T)1= 27oC + 273 = 300 K
E botsitsoe : mocheso oa ho qetela (T2)
Jawab :
Mocheso oa kamore ke 327oC.
3. Mabili a sethuthuthu a na le khatello ea ho lekanya ea 2 atm mochesong oa 27oC. Ka mora hore sethuthuthu se tsamaiswe, mocheso o ka hare ho thaere o fetoha ho 47oC. Haeba katoloso e hlokomolohuoa, kgatello ya moya e ka hara thaere e fetoha ho...

Fetolela kgatello ya tekanyo ho ba kgatello e feletseng. Kgatello e feletseng = kgatello ya tekanyo + kgatello ya sepakapaka
Hoa tsebahala :
Khatello ea sepakapaka = 1 atm = 1 x 105 Pascal
Khatello ea pele ea ho lekanya = 2 atm = 2 x 105 Pascal
Khatello e feletseng ea pele (P)1) = 1 atm + 2 atm = 3 atm = 3 x 105 Pascal
Mocheso oa pele (T)1= 27oC + 273 = 300 K
Mocheso oa ho qetela (T)1= 47oC + 273 = 320 K
E botsitsoe : Khatello ea ho qetela ea tekanyo
Jawab :
Kgatelelo ya ho qetela ya tekanyo = kgatelelo e feletseng ya ho qetela – kgatelelo ya sepakapaka
Khatello ea tekanyo ea ho qetela = 3,2 atm - 1 atm
Khatello ea tekanyo ea ho qetela = 2,2 atm
