A) critical temperature
B) Boyle temperature
C) 300K
D) inversion temperature
Correct Answer: A
Solution :
The temperature of a gas above which it cannot be liquified whatever high pressure is applied, is known as its critical temperature. \[{{T}_{c}}=\frac{8a}{27Rb}\] \[{{T}_{c}}\] for \[C{{O}_{2}}\xrightarrow{{}}{{31.1}^{o}}C\] \[{{T}_{c}}\] for \[{{H}_{2}}\xrightarrow{{}}-{{240}^{o}}C\] \[{{T}_{c}}\] for \[{{O}_{2}}\xrightarrow{{}}-{{118}^{o}}C\] Helium has the least \[{{T}_{c}}\].
