Laʻana o ke kānāwai o Charles (isobaric/constant pressure)

3 mau laʻana o ke kānāwai o Charles (isobaric/constant pressure)

1. I loko o kahi pahu pani, hoʻonui ke kinoea i hiki ke loli kona nui i 3 manawa o kona nui mua (V = ka nui mua, T = ka mahana mua). Hoʻololi ka mahana o ke kinoea i…

Pahana
Ua ʻike ʻia :
Ka nui mua (V₁) = V
Ka leo hope loa (V₂) = 3V
Mahana mua (T₁) = T
Ua nīnau ʻia : ka mahana hope loa (T₂)
Pane :
Ke kānāwai o Charles (kaʻina hana isobaric a i ʻole ke kaomi mau) :
Hoʻololi ka mahana o ke kinoea i 3 manawa o ka mahana mua.

2. I ka wā mua, he nui ka nui o ke kinoea kūpono (V) a he mahana T. Inā hele ke kinoea i kahi kaʻina hana isobaric i lilo ai kona mahana i pālua i ka mahana mua, e loli ka nui o ke kinoea i...

Pahana
Ua ʻike ʻia :
Ka nui mua (V₁) = V
Mahana mua (T₁) = T
Mahana hope loa (T₂) = 2T
Ua nīnau ʻia : ka leo hope loa (V₂)
Pane :
Hoʻololi ka nui o ke kinoea i 2 manawa o ka nui mua.

3. Aia i loko o kahi ipu pani ʻia kahi kinoea nona ka nui o 2 lita a me ka mahana o 27^oC. Inā lilo ka nui o ke kinoea i 3 lita, lilo ka mahana o ke kinoea i...
Pahana
Ua ʻike ʻia :
Ka nui mua (V₁) = 2 lita = 2 dm³ = 2x10^-3 m³
Ka leo hope loa (V₂) = 3 lita = 3 dm³ = 3x10^-3 m³
Mahana mua (T₁) = 27^oC + 273 = 300 K
Ua nīnau ʻia : ka mahana hope loa (T₂)
Pane :
Hoʻololi ka mahana o ke kinoea i 450 Kelvin a i ʻole 177^oC.
