A gas with a = 0 cannot be liquified.

Assertion: Ideal gas does not show Joule-Thomson effect as well as they cannot be liquefied. Reason: ((delE)/(delV))_(T) and ((delT)/(delP))_(H) for ideal gas is zero.

The isotherms of a gas are shown below : Among the following (i) At T_1 , the gas cannot be liquified (ii) At point B, liquid starts to appear at T_2 (iii) T_C is the highest temperature at which the gas can be liquified (iv) At point A , a small increase in pressure condense the whole system to a liquid. teh correct statements are :

Temperature above which gas cannot be liquefied is called .........

The gas above T_(c ) cannot be liquefied.

For every gas, there is a certain temperature above which it cannot be liquefied. It this statement correct ?

Statement-1. Less is the critical temperature of a gas, more easily it can be liquefied. Statement-2. Critical temperature is the temperature above which a gas cannot be liquiefied applying any amount of pressure.

The temperature above which the gas cannot be liquefied by any amount of pressure is called…………………...
