The forces of attraction between the particles in a solid are the strongest, in liquids are less strong whereas in gases are the weakest. Now, out of water, sugar and oxygen :
(i) oxygen is a gas, so it has the weakest forces of attraction between its particles.
(ii) water is a liquid, so it has stronger forces of attraction between its particles (than oxygen).
(iii) sugar is a solid, so it has the strongest forces of attraction between its particles.
Thus, the increasing order of forces of attraction between the particles of water, sugar and oxygen will be :
oxygen `lt` water `lt` sugar
