Questions & Step-by-Step Solutions

What is the relationship between surface tension and the shape of a liquid droplet?
  • Step 1: Understand that surface tension is a force that acts on the surface of a liquid.
  • Step 2: Recognize that this force pulls the molecules at the surface of the liquid together.
  • Step 3: Know that liquids naturally try to minimize their surface area to reduce the effect of surface tension.
  • Step 4: Realize that the shape with the smallest surface area for a given volume is a sphere.
  • Step 5: Conclude that because of surface tension, liquid droplets form a spherical shape to minimize their surface area.
