Statement 1: When a magnet is dipped in liquid oxygen, some of it sticks to the magnet. Statemetn 2: Oxygen is paramgnetic in nature.

Liquid oxygen remains suspended between two pole faces of a magnet because it is

If liquid level falls in a capillary then radius of capillary will

The correct increasing order of the boiling points of liquid oxygen, liwid argon and liquid nitrogen present in liquid air is:
