Questions & Step-by-Step Solutions

If a drop of liquid is placed on a flat surface, what shape will it take due to surface tension?
  • Step 1: Understand that a drop of liquid is made up of many tiny molecules.
  • Step 2: Know that these molecules are attracted to each other, which creates a force called surface tension.
  • Step 3: Recognize that surface tension tries to minimize the surface area of the liquid drop.
  • Step 4: Realize that a sphere has the smallest surface area for a given volume compared to other shapes.
  • Step 5: Conclude that because of surface tension, the drop of liquid will form a spherical shape.
  • Surface Tension – The cohesive force between liquid molecules that causes the liquid to minimize its surface area.
  • Shape of Liquid Drops – A drop of liquid adopts a spherical shape due to surface tension, as a sphere has the least surface area for a given volume.
