Mehlala e 3 ea molao oa Boyle (mocheso o sa fetoheng oa isothermal)
1. Karolo e itseng ea khase e loketseng qalong e na le khatello ea P le bophahamo ba V. Haeba khase e feta ts'ebetsong ea isothermal hoo khatello e bang makhetlo a mane ho feta khatello ea pele, bophahamo ba khase bo fetoha ho ...
Puisano
Hoa tsebahala :
Khatello ea pele (P)1) = P
Khatello ea ho qetela (P)2) = 4P
Molumo oa pele (V)1) = V
E botsitsoe : bophahamo ba ho qetela ba khase (V2)
Jawab :
Molao oa Boyle (mokhoa oa mocheso o sa fetoheng kapa o sa fetoheng) :
PV = e sa fetoheng
P1 V1 = P.2 V2
(P)(V) = (4P)(V)2)
V = 4 V2
V2 = V / 4 = ¼ V
Bophahamo ba khase bo fetoha ho ba ¼ ea bophahamo ba pele.
2. Ka setshelong se koetsoeng, khase e atoloha hoo bophahamo ba yona bo fetohang habeli ho feta bophahamo ba pele (V = bophahamo ba pele, P = kgatello ya pele). Kgatello ya khase e fetoha ho…

Hoa tsebahala :
Khatello ea pele (P)1) = P
Molumo oa pele (V)1) = V
Moqolo oa ho qetela (V)2) = 2V
E botsitsoe : kgatello ya ho qetela (P2)
Jawab :
P1 V1 = P.2 V2
PV = P2 (2V)
P=P2 (2)
P2 = P / 2 = ½ P
Khatello ea khase e fetoha ka makhetlo a halofo ho feta khatello ea pele.
3. Ka sejaneng se koetsoeng ho na le khase e nang le khatello ea 2 atm le bophahamo ba litara e le 1. Haeba khatello ea khase e fetoha 4 atm joale bophahamo ba khase bo tla ba...

Hoa tsebahala :
Khatello ea pele (P)1) = 2 atm = 2 x 105 Pascal
Khatello ea ho qetela (P)2) = 4 atm = 4 x 105 Pascal
Molumo oa pele (V)1) = lilithara tse 1 = 1 dm3 = 1x10-3 m3
E botsitsoe : Molumo oa ho qetela (V)2)
Jawab :
P1 V1 = P.2 V2
(2x105)(1 x 10-3) = (4 x 105) V2
(1)(1 x 10-3) = (2) V2
1: x 10-3 = (2) V2
V2 = ½ x 10-3
V2 = 0,5x10-3 m3 = 0,5 dm3 = 0,5 litara
