which of the following gases can be liquefied at -5 °c

a. compound A (critical point: 0 degrees C, 10 atm)

b. compound B (critical point: -2 degrees C, 12 atm)

c. compound D (critical point -15 degrees C,12 atm)

d. compound E (critical point -7 degrees C, 10 atm)

Solution

A gas can\'t be liquified above critical temparature whatever the range of pressure is applied so any gas can be liquified below it\'s critical temparature on applying pressure. Hence a temparature below to -5°C is -15° & -7°C. Hence options are \'c\' & \'d\'
