A) \[{{H}_{2}}O\]
B) \[N{{H}_{3}}\]
C) \[C{{O}_{2}}\]
D) \[{{O}_{2}}\]
Correct Answer: B
Solution :
The gases for which critical temperature is high, have strong forces of attraction and thus, can be liquefied easily. Among the given gases, \[{{H}_{2}}O\] has the highest critical temperature, ie, 647 K but cooling starts from 500 K, so it is not considered. Critical temperature of \[N{{H}_{3}}\] ranks second, thus it will liquify first.You need to login to perform this action.
