Molao oa Gay-Lussac (bophahamo bo sa fetoheng) - mathata le litharollo

1. Ke sebetsana le likhase qalong li na le khatello ea P le mocheso oa T. Khase e feta ts'ebetsong ea isochoric e le hore khatello ea ho qetela e be makhetlo a mane ho feta khatello ea pele. Mocheso oa ho qetela oa khase ke ofe?

Tse tsejoang:

Kgatelelo ya pele (P ₁ ) = P

Kgatelelo ya ho qetela (P ₂ ) = 4P

Mocheso oa pele (T ₁ ) = T

Ho batloa: Mocheso oa ho qetela (T ₂ )

Tharollo:

Mokhoa oa molao oa Gay-Lussac :

Mocheso oa ho qetela o ba makhetlo a mane ho feta mocheso oa pele.

2. Ka setshelong se koetsoeng, likhase tse loketseng qalong li na le mocheso oa 27 ^o C. Haeba khatello ea ho qetela e ba makhetlo a mabeli ho feta khatello ea pele, mocheso oa ho qetela ke ofe?

Tse tsejoang:

Kgatelelo ya pele (P ₁ ) = P

Kgatelelo ya ho qetela (P ₂ ) = 2P

Mocheso oa pele (T ₁ ) = 27 ^o C + 273 = 300 K

Ho batloa: Mocheso oa ho qetela (T ₂ )

3. Thaere e tlatswa ho fihlela kgatellong ya 2 atm ho 27°C. Kamora ho kganna, mocheso ka hare ho thaere o nyolohela ho 47°C. Kgatello ka hare ho thaere ke efe jwale?

Tse tsejoang:

Khatello ea sepakapaka = 1 atm = 1 x 10 ⁵ Pa

Kgatelelo ya pele ya tekanyo = 2 atm = 2 x 10 ⁵ Pa

Kgatelelo e feletseng ya pele (P ₁ ) = 1 atm + 2 atm = 3 atm = 3 x 10 ⁵ Pa

Mocheso oa pele (T ₁ ) = 27 ^o C + 273 = 300 K

Mocheso oa ho qetela (T ₁ ) = 47 ^o C + 273 = 320 K

Ho batloa: Thempereichara ea ho qetela ea tekanyo

Tharollo:

Kgatelelo ya ho qetela ya tekanyo = kgatelelo e feletseng ya ho qetela – kgatelelo ya sepakapaka

Khatello ea ho qetela ea tekanyo = 3.2 atm - 1 atm

Khatello ea ho qetela ea tekanyo = 2.2 atm
