Mohlala oa ho sebelisa molao oa pele oa thermodynamics ts'ebetsong ea isochoric (molumo o sa fetoheng)

3 Mehlala ea lipotso mabapi le ts'ebeliso ea molao oa pele oa thermodynamics lits'ebetsong tsa isochoric (bophahamo bo sa fetoheng)

1. Kerafo ea khatello (P) khahlanong le bophahamo ba modumo (V) ba khase e fetang ts'ebetsong ea isochoric. Mosebetsi o etsoang ke khase ts'ebetsong ea AB ke…

Puisano
Ts'ebetso AB = ts'ebetso ea isochoric (bophahamo bo sa fetoheng). Ka bophahamo ba isochoric, bophahamo ba khase (le bophahamo ba sebaka) ha bo fetohe kahoo ha ho mosebetsi o etsoang ke khase.

2. Li-mole tse tharo tsa khase ea monatomic mochesong oa 47^oC le kgatello 2 x 10⁵ Pascal o feta ts'ebetsong ea isochoric ho fihlela khatello e eketseha ho fihlela ho 3 x 10⁵ Pascal. Phetoho ea matla a ka hare a khase ke… Khase e sa fetoheng ea bokahohle (R) = 8,315 J/mol.K
Puisano
Hoa tsebahala :
Mocheso oa pele (T)₁= 47^oC + 273 = 320 K
Khatello ea pele (P)₁) = 2 x 10⁵ Pa
Khatello ea ho qetela (P)₂) = 3 x 10⁵ Pa
Khase e sa fetoheng ea bokahohle (R) = 8,315 J/mol.K
Palo ea li-moles (n) = 3
E botsitsoe Liphetoho tsa matla khase
Jawab :
Mokhoeng oa isochoric, bophahamo ba modumo bo lula bo tsitsitse kahoo ha ho mosebetsi o etsoang ke khase (W = 0).
Molao oa Pele oa Thermodynamics :
Ho latela tlhahiso ea foromo ena, ho fihletsoe qeto ea hore ts'ebetsong ea isochoric, mocheso o eketsoang tsamaisong (Q) o etsa hore matla a ka hare a sistimi (U) a eketsehe. Ka lehlakoreng le leng, mocheso o lokolloang ke sistimi o etsa hore matla a ka hare a sistimi a fokotsehe. Phetoho ea matla a ka hare a khase ke bokae? Phetoho ea matla a ka hare a khase e baloa ho sebelisoa foromo ea matla a ka hare e ka tlase.
Matla ka khase :
E le ho bala phetoho ea matla a ka hare, mocheso oa ho qetela (T) o tlameha ho tsejoa.₂Bala T₂ ho sebelisoa mokhoa oa molao oa Gay-Lussac.
Molao oa Gay-Lussac (molumo oa isochoric/o sa fetoheng) :
Bala phetoho ea matla khase:
Phetoho ea matla a ka hare a khase ke 5986,8 Joules.

3. Kakaretso ea limolek'hule tse 0,2 tsa khase ea monatomic mochesong oa 27^oC e ka har'a sejana se koetsoeng. Mocheso o lokelang ho monngoa ho eketsa mocheso oa khase ho 400 K ke… Khase e sa fetoheng ea bokahohle (R) = 8,315 J/mol.K
Puisano
Hoa tsebahala :
Palo ea li-moles (n) = 0,2 mol
Mocheso oa pele (T)₁= 27^oC + 273 = 300 K
Mocheso oa ho qetela (T)₂) = 400 K
Khase e sa fetoheng ea bokahohle (R) = 8,315 J/mol.K
E botsitsoe : Mocheso o monyela (Q)
Jawab :
Mokhoeng oa isochoric, bophahamo ba modumo bo lula bo tsitsitse kahoo ha ho mosebetsi o etsoang ke khase (W = 0).
Molao oa Pele oa Thermodynamics :
Mocheso o monyelang (Q) = keketseho ea matla a ka hare a khase (U). Phetoho ea matla a ka hare a khase e baloa ho sebelisoa foromo ea matla a ka hare e ka tlase.
Matla ka khase :
Mocheso o monngoang ke khase = phetoho ea matla a ka hare = 249,45 Joules.
