1. Ụfọdụ gas ndị dị mma na mbụ nwere nrụgide P na olu V. Ọ bụrụ na gas ahụ na-agafe usoro isothermal nke na nrụgide ikpeazụ ga-aghọ okpukpu anọ nke nrụgide mbụ, mgbe ahụ olu ikpeazụ nke gas ga-abụ…
A maara:
Nrụgide mbụ (P1 ) = P
Nrụgide ikpeazụ (P2 ) = 4P
Mpịakọta mbụ (V1 ) = V
Achọrọ: Mpịakọta Ikpeazụ (V 2 )
Ngwọta:
Usoro iwu Boyle :
PV = mgbe niile
P 1 V 1 = P 2 V 2
(P)(V) = (4P)( V2 )
V = 4 V 2
V 2 = V / 4 = ¼ V
Olu ikpeazụ nke gas bụ ¼ ugboro olu mbụ.

2. N'ime akpa mechiri emechi, gas ahụ na-agbasa nke na olu ikpeazụ ga-aghọ okpukpu abụọ nke olu mbụ (V = olu mbụ, P = nrụgide mbụ). Nrụgide ikpeazụ nke gas bụ…
A maara:
Nrụgide mbụ (P1 ) = P
Mpịakọta mbụ (V1 ) = V
Olu ikpeazụ (V2 ) = 2V
Achọtara : Nrụgide ikpeazụ ( P2 )
Ngwọta:
P 1 V 1 = P 2 V 2
PV = P2 ( 2V )
P = P 2 (2)
P 2 = P / 2 = ½ P
Nrụgide gas na-aghọ ½ ugboro nrụgide mbụ.

3. N'ime akpa mechiri emechi, gas nwere nrụgide nke 2 atm na olu nke 1 lita. Ọ bụrụ na nrụgide gas aghọọ 4 atm mgbe ahụ olu gas na-aghọ...
A maara:
Nrụgide mbụ (P1 ) = 2 atm = 2 x 10 5 Pa
Nrụgide ikpeazụ (P2 ) = 4 atm = 4 x 10 5 Pa
Mpịakọta mbụ (V 1 ) = lita 1 = 1 dm 3 = 1 x 10 -3 m 3
Achọrọ : Mpịakọta ikpeazụ (V 2 )
Ngwọta:
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
