Air molecules have negligible force of attraction,while wood molecules are closely packed.

Vedclass · Answer

(C) Air molecules are very far from each other due to the negligible force of attraction working between them. Therefore,our hand gets sufficient space to move through the air,and we can easily displace air molecules by applying a small force.In contrast,a solid block of wood has particles that are very closely packed with strong intermolecular forces of attraction. Because of this rigid structure,our hand cannot move through it without applying a massive amount of force in a precise direction,which is why a karate expert is required.

Give reasons: We can easily move our hand in air but to do the same through a solid block of wood,we need a karate expert.
