Which one of the following statement is correct?

Options

  1. ASurface energy is potential energy per unit length
  2. BSurface tension is work done per unit area
  3. CSurface tension is work done per unit length
  4. DSurface energy is work done per unit force

Correct answer

B. Surface tension is work done per unit area

Step-by-step solution

Surface tension is the force applied per unit length or work done (or energy) per unit area of a liquid surface. While surface energy is the amount of work done per unit area by the force.
