Answer 1

Answer:

Surface tension is measured as the energy required to increase the surface area of a liquid by a unit of area. The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:

A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions.

A molecule at the surface of a liquid experiences only net inward cohesive forces.

A microscopic view of water illustrates the difference between molecules at the surface of a liquid and water molecules within a liquid

Answer 2

Answer:

The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules: A molecule in the bulk liquid experiences cohesive forces with other molecules in all directions. A molecule at the surface of a liquid experiences only net inward cohesive forces.
