20. 1. It is the action or property of
molecules adhering to one another
due to mutual attraction.
surface tension
cohesive force
adhesive force
viscosity
21. 2. It is the resistance of a fluid (liquid or
gas) to a change in shape, or
movement of neighbouring portions
relative to one another.
cohesive force
surface tension
adhesive force
viscosity
22. 3. This is described as a force of
attraction (attractive force) that
attracts all physical forms having
mass.
strong nuclear force
gravitation force
electromagnetic force
weak nuclear force
23. 4. This force is strong enough that it overcomes
the repulsive force between the two positively
charged protons, allowing protons and
neutrons to stick together in an unimaginably
small space.
strong nuclear force
gravitation force
electromagnetic force
weak nuclear force
24. 5. It is the movement of liquids within

between a liquid and the solid surfaces
that surround it.
intramolecular forces
intermolecular forces
surface tension
capillary action
