Solids have definite shapes.This is because

  • A.The forces of cohesion of the molecules within are very much less in them
  • B.The forces of cohesion are very large
  • C.The forces of adhesion are large
  • D.The forces of adhesion are less

Answer: B

Because the forces of cohesion between the molecules are very large.

In a solid the intermolecular forces hold each molecule near a fixed lattice site, so it can only vibrate about that point. In liquids these forces are weaker and molecules can slide past one another, so a liquid takes the shape of its container.
