Question

A gas cannot be liquefied above: (A) critical temperature (B) Boyle temperature (C) 300K (D) inversion temperature

Tardigrade Admin · Accepted Answer

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{8 a}{27 R b} T_{c}

for

C O_{2} \to 31. 1^{\circ} C T_{c}

for

H_{2} \to - 24 0^{\circ} C T_{c}

for

O_{2} \to - 11 8^{\circ} C

Helium has the least

T_{c}
