Ke kānāwai o Gay-Lussac (ka leo mau) - nā pilikia a me nā hoʻonā

1. I ka wā mua, loaʻa i nā kinoea ke kaomi P a me ka mahana T. Ke hana nei ke kinoea i ke kaʻina hana isochoric i lilo ai ke kaomi hope loa i 4 manawa o ke kaomi mua. He aha ka mahana hope loa o ke kinoea?

ʻIke ʻia:

Kaomi mua (P ₁ ) = P

Kaomi hope loa (P ₂ ) = 4P

Ka mahana mua (T ₁ ) = T

Makemake ʻia: Mahana hope loa (T ₂ )

Lōlā:

ʻO ke ʻano o ke kānāwai o Gay-Lussac :

ʻEhā manawa ka mahana hope loa o ka mahana mua.

ʻAʻole maopopo

2. I loko o kahi pahu pani, ʻo ka mahana o nā kinoea kūpono i ka wā mua he 27 ^o C. Inā lilo ke kaomi hope loa i 2 manawa o ke kaomi mua, he aha ka mahana hope loa?

ʻIke ʻia:

Kaomi mua (P ₁ ) = P

Kaomi hope loa (P ₂ ) = 2P

Ka mahana mua (T ₁ ) = 27 ^o C + 273 = 300 K

Makemake ʻia: Mahana hope loa (T ₂ )

Lōlā:

ʻAʻole maopopo

3. Ua hoʻopiha ʻia kahi huila i kahi kaomi anakahi o 2 atm ma 27°C. Ma hope o ka hoʻokele ʻana, piʻi ka mahana i loko o ka huila i 47°C. He aha ke kaomi i loko o ka huila i kēia manawa?

ʻIke ʻia:

ʻO ke kaomi lewa = 1 atm = 1 x ¹⁰⁵ Pa

ʻO ke kaomi ana mua = 2 atm = 2 x 10 ⁵ Pa

ʻO ke kaomi paʻa mua (P ₁ ) = 1 atm + 2 atm = 3 atm = 3 x 10 ⁵ Pa

ʻO ka mahana mua (T ₁ ) = 27 ^o C + 273 = 300 K

ʻO ka mahana hope loa (T ₁ ) = 47 ^o C + 273 = 320 K

Makemake ʻia: ʻO ka mahana hope loa

Lōlā:

ʻO ke kaomi ana hope loa = kaomi hope loa - kaomi lewa

ʻO ke kaomi hope loa = 3.2 atm - 1 atm

ʻO ke kaomi hope loa = 2.2 atm
