Question 5
1 / -0

Direction (Q. Nos. 5-9) This sectionis based on statement I and Statement II. Select the correct answer from the code given below.
Q.
Statement I : Gases do not liquefy above th e ir T_c (critical temperature), even on applying high pressure.
Statement Il : Above T_c , m olecular speed is high and interm olecular attractions cannot hold the molecules together, because they escape due to high speed.
