Classify each statement as an example of adhesion, cohesion, or surface tension. Drag each statement to the appropriate bin. A sewing needle floats when it is placed gently on top of water in a bucket. Water molecules ding to plant cell walls. A water strider runs across a pond without breaking the surface. A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface. Water molecules cling to the side of a beaker. Water molecules are attracted to each other.

A sewing needle floats when it is placed gently on top of water in a bucket - surface tension

Water molecules ding to plant cell walls - adhesion

A water strider runs across a pond without breaking the surface - surface tension

A drop of water spilled on a table forms a drop on the table, rather than spreading out over the surface - cohesion

Water molecules cling to the side of a beaker - adhesion

Water molecules are attracted to each other - cohesion

Explanation:

The surface tension refers to the tendency of the surface of a liquid to remain unbroken by an external force due to the cohesive property of the molecules of the liquid. Instead of being broken, the surface of the liquid stretches like an elastic membrane.

The adhesive property of a liquid, also known as the force of adhesion, refers to the property of the molecules of the liquid to stick to other molecules while cohesive property or cohesion refers to the property of molecules of liquids to stick to themselves.

Hence,

Surface tension

Cohesion

Adhesion

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.
