1. Ngikhipha amagesi esitsheni esivaliwe ekuqaleni nginomthamo u-V kanye nokushisa u-T. Izinga lokushisa lokugcina lingu-5/4T kanti ingcindezi yokugcina ingu-2P. Iyini ivolumu yokugcina yegesi?
Kwaziwa:
Umthamo wokuqala (V 1 ) = V
Izinga lokushisa lokuqala (T1 ) = T
Izinga lokushisa lokugcina (T2 ) = 5/4 T
Ingcindezi yokuqala (P 1 ) = P
Ukucindezela kokugcina (P 2 ) = 2P
Okufunwayo: Umqulu Wokugcina (V 2 )

2. Thola ivolumu yama-mol angu-2.00 wamagesi (igesi ekahle) ku-STP. I-STP = Izinga Lokushisa Elijwayelekile kanye Nokucindezela.
Kwaziwa:
Ama-moles egesi (n) = ama-moles amabili eqhwa
Izinga lokushisa elijwayelekile (T) = 0 o C = 0 + 273 = 273 Kelvin
Ukucindezela okujwayelekile (P) = 1 atm = 1.013 x 10 5 Pa
I-Universal gas constant (R) = 8.315 Joule/mol e .Kelvin
Okufunwayo : Umthamo wamagesi (V)
Isixazululo:
Isilinganiso somthetho wegesi ofanele (ngenani lama-moles, n)
Umthamo wama-moles amabili amagesi ungamalitha angu-44.8.
Umthamo we-mole eyi-1 yamagesi ungamalitha angu-45.4 / 2 = amalitha angu-22.4.
Umthamo we-mole eyi-1 yanoma iyiphi igesi ungamalitha angu-22.4.

3. Amalitha angu-4 egesi yomoya-mpilo anokushisa okungu-27°C kanye nokucindezela okungu-2 atm (1 atm = 10 5 Pa) esitsheni esivaliwe. I-Universal gas constant (R) = 8.314 J.mol e −1 .K −1 kanye nenombolo ka-Avogadro ( N A ) = 6.02 x 10 23 ama-molecule/mol e . Ayini ama-molecule egesi yomoya-mpilo esitsheni?
Kwaziwa:
Umthamo wamagesi (V) = 4 amalitha = 4 dm 3 = 4 x 10 -3 m 3
Izinga lokushisa lamagesi (T) = 27 o C = 27 + 273 = 300 Kelvin
Ukucindezela kwamagesi (P) = 2 atm = 2 x 10 5 Pa
I-Universal gas constant (R) = 8.314 J.mol e −1 .K −1
Inombolo ka-Avogadro (N A ) = 6.02 x 10 23
Okufunwayo : Yimaphi ama-molecule amagesi e-oxygen esitsheni (N)
Isixazululo:
Ku-molecule eyodwa yamagesi e-oxygen, kune-molecule ye-oxygen engu-1.93 x 10 23.

4. Isitsha esinegesi ye-neon (Ne, isisindo se-athomu = 20 u) ekushiseni okujwayelekile kanye nokucindezela (STP ) sinomthamo ongu-2 m 3. Thola isisindo segesi ye-neon!
Kwaziwa:
Isisindo se-athomu se-neon = 20 gram/mol e = 0,02 kg/mol e
Izinga lokushisa elijwayelekile (T) = 0 o C = 273 Kelvin
Ukucindezela okujwayelekile (P) = 1 atm = 1.013 x 10 5 Pascal
Umthamo (V) = 2 m 3
Okufunwayo : isisindo (m) segesi ye-neon
Isixazululo:
Kumazinga okushisa ajwayelekile kanye nengcindezi (STP), 1 mole kwanoma yimaphi amagesi, faka igesi ye-neon, inomthamo I-22.4 ilithas = 22.4 dm3 = 0.0448m3.
Ku-2 m3 , kune -44.6 moles yegesi ye-neon.
Isisindo se-athomu segesi ye-neon singamagremu angu-20 nge-mole.
Lokhu kusho ukuthi ku-mole eyodwa kukhona amagremu angu-20 noma u-0.02 kg wegesi ye-neon. Ngoba ku-mole eyodwa kukhona u-0.02 kg wegesi ye-neon bese kuthi ku-mole engu-44.6 kukhona ama-moles angu-44.6 x 0.02 kg/mole = 0.892 kg = 892 amagremu wegesi ye-neon.
