Question

Force of attraction between the molecules of different substances is called— (a) surface tension (b) cohesive force (c) adhesive force (d) none of above

Answer 1

(c) adhesive force
Because adhesive means to combine and combining force can b Gravitational force or magnetic force

Answer 2

Answer: (c) adhesive force

Explanation:

1. Surface tension is the net downward force acting on the surface of liquids due to the cohesive nature of liquids. The molecules present on the surface are strongly attracted by the molecules present below the surface and thus act as a stretched membrane.  

The surface acquires a minimum surface are and thus acquire a spherical shape.

2. Cohesive forces are the forces which are present between similar molecules such as hydrogen bonding in water.

3. Adhesive forces are the forces which are present between different molecules such as Hydrogen bonding between water and HCl.
