A gas can be liquefied at temperature T and pressure P provided `"_____________"`.

A

`T gt T_(c ) and P gt P_(c )`

B

`T lt T_(c ) and P gtP_(c )`

C

`T gt T_(c ) and P gt P_(c )`

D

`T gt T_(c ) and P lt P_(c )`

Text Solution

Verified by Experts

The correct Answer is:
B
Gases can be liquefied if temperature is lower than critical temperature `(TltT_(c ))` and pressure is greater than critical pressure `(p gt p_(c ))`

CO_(2) gas can be liquefied under pressure between

The essential conditions for liquefaction of gases were discovered by Andrews in 1869 as a result of his study of pressure-volume-temperature relationship for CO_(2) . If was found that above a certain temperature, it was impossible to liquefy a gas whatever the pressure was applied. The temperature below which the gas can be liquefied by the application of pressure alone is called critical temperature (T_(c)) . The pressure required to liquefy a gas at this temperature is called the critical pressure (P_(c)) . The volume occupied by one mole of the substance at the critical temperature and pressure is called critcal volume. Critical constants are related with van der Waals' constant as follows: V_(c) = 3b, P_(c) = (a)/(27b^(2)), T_(c) = (8a)/(27 Rb) Gas A and can be liquefied at room temperature by applying pressure but gas B cannot. This reflects:

Assertion : A gas can be liquified at any temperature by increase of pressure alone. Reason : On increasing pressure the temperature of gas decreases
