Ithiyori ye-kinetic yamagesi - izinkinga nezixazululo

1. Ngiphatha amagesi esitsheni esivaliwe ekuqaleni nginomthamo u-V kanye nomfutho u -P . Uma umfutho wokugcina ungu-4P futhi umthamo ugcinwa ungaguquguquki, siyini isilinganiso samandla okuqala e-kinetic namandla okugcina e-kinetic.

Kwaziwa:

Ingcindezi yokuqala (P ₁ ) = P

Ukucindezela kokugcina (P ₂ ) = 4P

Umthamo wokuqala (V ₁ ) = V

Umqulu wokugcina (V ₂ ) = V

Okufunwayo: Isilinganiso samandla okuqala e-kinetic namandla okugcina e-kinetic (K E ₁ : K E ₂ )

Isixazululo:

Ubudlelwano phakathi kwengcindezi (P), ivolumu (V) kanye namandla e-kinetic (KE) yamagesi afanele :

2. Iyini isilinganiso samandla e-kinetic esijwayelekile sama-molecule kugesi efanelekile ku-57 ^o C.

Kwaziwa:

Izinga lokushisa legesi (T) = 57 ^o C + 273 = 330 Kelvin

I- Boltzmann 's constant (k) = 1.38 x 10 ^-23 Joule/Kelvin

Okufunwayo: Amandla ajwayelekile e-kinetic okuhumusha

Isixazululo:

Ubudlelwano phakathi kwamandla e-kinetic (KE) kanye nokushisa kwegesi (T):

Amandla ajwayelekile e-kinetic okuhumusha:

3. Igesi ku- 27 ^° C esitsheni esivaliwe . Uma amandla e-kinetic egesi enyuka ngokuphindwe kabili kunamandla okuqala e-kinetic, ngakho-ke izinga lokushisa lokugcina legesi li...

Kwaziwa:

Izinga lokushisa lokuqala (T ₁ ) = 27 ^o C + 273 = 300 K

Amandla okuqala e-kinetic = KE

Amandla okugcina e-kinetic = 4 K E

Okufunwayo: Izinga lokushisa lokugcina ( _T2 )

Isixazululo:

4. Igesi efanelekile isesitsheni esivaliwe, iyashiswa ukuze ijubane lokugcina elimaphakathi lezinhlayiya zegesi likhuphuke ngokuphindwe kathathu kunejubane lokuqala elimaphakathi. Uma izinga lokushisa lokuqala legesi lingu- 27 ^° C, khona-ke izinga lokushisa lokugcina legesi efanelekile lingu…

Kwaziwa:

Izinga lokushisa lokuqala = 27 ^o C + 273 = 300 Kelvin

Ijubane lokuqala = v

Ijubane lokugcina = 2v

Okufunwayo : Izinga lokushisa lokugcina legesi elifanele

Isixazululo:

Ijubane lokugcina elimaphakathi = 2 x ijubane lokuqala elimaphakathi

5. Ama-mole amathathu egesi asendaweni yomthamo wamalitha angu-36. I-molecule ngayinye yegesi inamandla e-kinetic angu-5 x 10 ^-21 Joules. I-Universal gas constant = 8.315 J/mole.K kanye ne-Boltzmann's constant = 1.38 x 10 ^-23 J/K. Iyini ingcindezi yegesi esitsheni.

Kwaziwa:

Inani lama-moles (n) = ama-moles angu-3

Umthamo = amalitha angu-36 = 36 dm ³ = 36 x 10 ^-3 m ³

I-Boltzmann's constant (k) = 1.38 x 10 ^-23 J/K

Amandla e-Kinetic (KE) = 5 x 10 ^–21 Joules

I-gesi engaguquki yonke (R) = 8.315 J/mole.K

Okufunwayo : Umfutho wegesi (P)

Isixazululo:

Bala izinga lokushisa usebenzisa i-equation yamandla e-kinetic egesi.

Bala ingcindezi yegesi usebenzisa i-th equation yomthetho wegesi ofanele (ngenani lama-moles, n):

I-PV = n RT

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

P (36 x 10 ^-3 ) = 6024.22

Umfutho wegesi ungu-1.67 x 10 ⁵ Pascal noma i-atmospheres engu-1.67.
