Ozizi Kinetic nke Gas - Nsogbu na Ngwọta

1. M na-azụta gas n'ime akpa mechiri emechi na mbụ nwere olu V na nrụgide P. Ọ bụrụ na nrụgide ikpeazụ bụ 4P ma a na-anọgide na olu ahụ, kedu ka oke nke ike kinetic mbụ na ike kinetic ikpeazụ si dị?

A maara:

Nrụgide mbụ (P1 ₎ = P

Nrụgide ikpeazụ (P2 ₎ = 4P

Mpịakọta mbụ (V1 ₎ = V

Mpịakọta ikpeazụ (V2 ₎ = V

Achọrọ: Oke nke ike kinetic mbụ na ike kinetic ikpeazụ (K E ₁ : K E ₂ )

Ngwọta:

Mmekọrịta dị n'etiti nrụgide (P), olu (V) na ike kinetic (KE) nke gas kacha mma :

Oke nke ike kinetic mbụ na ike kinetic ikpeazụ:

2. Kedu ka ike ntụgharị nke molekul dị n'ime gas zuru oke na 57 ^o C?

A maara:

Okpomọkụ nke gas (T) = 57 ^o C + 273 = 330 Kelvin

Ọnụọgụ Boltzmann (k) = 1.38 x 10 ^-23 Joule/Kelvin

Achọrọ: Ike ntụgharị nkezi

Ngwọta:

Mmekọrịta dị n'etiti ike kinetic (KE) na okpomọkụ nke gas (T):

3. Gas dị na 27 oC n'ime akpa mechiri emechi. Ọ ^bụrụ na ike kinetic nke gas ahụ amụbaa ugboro abụọ ike kinetic mbụ, yabụ okpomọkụ ikpeazụ nke gas ahụ bụ…

A maara:

Okpomọkụ mbụ (T ₁ ) = 27 ^o C + 273 = 300 K

Ike kinetic mbụ = KE

Ike kinetic ikpeazụ = 4 K E

Achọrọ: Okpomọkụ ikpeazụ ( _T2 )

Ngwọta:

4. A na-etinye gas zuru oke n'ime akpa mechiri emechi, a na-ekpo ọkụ ka ọsọ ikpeazụ nke ihe ndị dị na gas na-abawanye site na ugboro atọ nke ọsọ mbụ. Ọ bụrụ na okpomọkụ gas mbụ bụ 27 ^o C, mgbe ahụ okpomọkụ ikpeazụ nke gas zuru oke bụ…

A maara:

Okpomọkụ mbụ = 27 ^o C + 273 = 300 Kelvin

Ọsọ mbụ = v

Ọsọ ikpeazụ = 2v

Achọrọ : Okpomọkụ ikpeazụ nke gas kacha mma

Ngwọta:

Ọsọ nkezi ikpeazụ = 2 x ọsọ nkezi mbụ

5. Mkpụrụ gas atọ dị n'ime oghere olu lita 36. Mkpụrụ gas ọ bụla nwere ike kinetic nke 5 x 10 ^-21 Joules. Igwe gas zuru ụwa ọnụ = 8.315 J/mole.K na Igwe Boltzmann nke na-agbanwe agbanwe = 1.38 x 10 ^-23 J/K. Kedu nrụgide gas dị na akpa ahụ?

A maara:

Ọnụọgụ nke ntụpọ (n) = ntụpọ atọ

Olu = lita 36 = 36 dm ³ = 36 x 10 ^-3 m ³

Ọnụọgụ Boltzmann (k) = 1.38 x 10 ^-23 J/K

Ike Kinetic (KE) = 5 x 10 ^–21 Joules

Igwe gas zuru ụwa ọnụ (R) = 8.315 J/mole.K

Achọtara : Nrụgide gas (P)

Ngwọta:

Gbakọọ okpomọkụ site na iji usoro nke ike kinetic nke gas.

Gbakọọ nrụgide gas site na iji usoro th nke iwu gas zuru oke (n'ọnụọgụ moles, n):

PV = n RT

P (36 x 10 ^-3 ) = (3)(8.315)(241.5)

P (36 x 10 ^-3 ) = 6024.22

Nrụgide gas bụ 1.67 x 10 ⁵ Pascal ma ọ bụ ikuku 1.67.
