Question

Cohesive forces are the forces acting

a.Between molecules of different materials

b.Between molecules of same materials

c.Between water and glass capillary tube

d.Due to gravity

Answer 1

Cohesive forces are the forces acting between molecules of the same materials.

• The force acting between the molecules of the same materials in a system is called cohesive force and the force acting between the molecules of different materials is called adhesive force.
• For example, if we take a glass of water then the force of attraction between the water molecules is the cohesive force and the force of attraction between the wall of the glass and water is adhesive force.
