States of matter
गैसों का द्रवण ( Liquefaction of gases)
states of matter by rahul khandelwal
HP = high pressore
LT = Low Temp.
Means A gas can be liqufied both by increasing pressure & decreasing Temp. (अर्थात एक गैस को उच्च दाब एवं निम्न ताप पर द्रवित किया जा सकता है )
Co2 gas can not liqufied at 35°C How
Co2 (35°C) so much pressure we apply.
Co2 (31.1°C) Co2 (Liquid)
Means Co2 can be liquied at 31.1°C
Means In liquefaction of gases is more than significant
यहाँ से 3 parameters हमें पढ़ने है |
|Critical Temp.||Critical pressure||Critical volume|
|The Temp. above which a gas cannot be liquefy how so much pressure we apply
|The pressure of gas at TC is known as Pc
|The volumes of 1 molar gas at Tc & Vc known as Vc
Trick- c comes at 3 position alphabetically and
NOTE= a & b are wonder as cons
NOTE:- Tc, Pc & Vc are different for different gases for Ex.
Co2 – Tc Pc Vc
31.1°C 79.3 bar ……….
|Critical Temp.||Boyle’s Temp||Inversion Temp|
|The Temp. at which a real gas behaves as an ideal gas is k/n as Boyle’s Temp.
|It is the double of Boyle’s Temp.
I can say
- – A gas can be liquefy ?
(a) Above TC Above PC
(b) Above TC Below PC
(c) Above TC Below PC
(d) Below TC Above PC
Trick – G l ACP को याद रखिये |
