गैसों का द्रवण Liquefaction of gases | States of matter

States of matter

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.

79.3 bar
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

T_c

P_c

V_c

The Temp. above which a gas cannot be liquefy how so much pressure we apply

The pressure of gas at T_C is known as Pc

Pc= a/27b²

The volumes of 1 molar gas at Tc & Vc known as Vc

Vc =3b

Trick- c comes at 3 position alphabetically and

V=b

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
T_c	T_c	T_i
T_c	The Temp. at which a real gas behaves as an ideal gas is k/n as Boyle’s Temp. T_B	It is the double of Boyle’s Temp. T_i
=	=	= 2

I can say

(a) Above T_CAbove P_C

(b) Above T_CBelow P_C

(d) Below T_CAbove P_C

Trick – G l ACP को याद रखिये |
