Question

Explain using kinetic theory what happens to the particles in oxygen as it is cooled down

Answer 1

As the temperature decreases, the molecules slow down. They become more attractive to each other  and at some point they slow to the point that they come so close that the liquid forms. with more temperature loss, the molecules even loose more energy and crystal lattice forms
